Description

HAIR TREATMENT COMPOSITIONS AND PROCESSES

The disclosure relates to hair treatment compositions and processes, in particular to impart cosmetic benefits such as revitalization and shine to the hair.

CONTEXT

It is well known that consumers desire cosmetic and care products that enhance the appearance of keratinous substrates such as hair, for example, by changing hair color, style, and/or shape, and/or by imparting various properties to the hair, such as shine and revitalization. Many of the products and processes known to improve the appearance of hair involve chemical treatment. The process of changing hair color, for example, may involve artificially coloring the hair, resulting in a different shade or color, and/or enhancing hair color, such as lightening dark hair to lighter shades.

Generally, hair lightening or hair dye formulations are prepared by mixing a base formula with an oxidizing agent, also known as a developer, just before use. Hydrogen peroxide is the most commonly used oxidizing agent in permanent hair coloring and lightening processes. However, once the developer and base formula are mixed, the oxidation reaction begins almost immediately. Therefore, the mixing step should not take place until the hair to be colored or lightened is ready for application. Furthermore, any remaining mixture after application cannot be stored for later use and must be discarded.

Although hair dyes and lightening products can effectively change hair color, these chemical processes also damage the hair fibers. Chemical hair styling processes, such as straightening or perming, also damage the hair fibers. This damage can manifest as split ends, breakage, unruly hair, and other issues, leaving hair feeling rough and looking dull and unhealthy. Therefore, consumers desire treatment products that offer cosmetic benefits, such as minimizing split ends and adding shine and/or softness.

It has now been surprisingly discovered that hydrogen peroxide can be used to impart beneficial cosmetic properties to hair. It has also been found that a synergistic combination of components provides unexpected stability to hair treatment compositions containing hydrogen peroxide. This disclosure therefore relates to hair treatment compositions and processes designed to provide cosmetic benefits such as shine, revitalization, fiber strength, and/or a healthy appearance, while avoiding or minimizing hair damage, particularly that associated with chemical processes used to improve hair appearance.

I. Compositions

Hair treatment compositions include hydrogen peroxide. In various embodiments, it may be useful to select a hydrogen peroxide-generating agent that can generate hydrogen peroxide in situ. For example, useful hydrogen peroxide-generating agents may be selected from urea peroxide; polymeric complexes that can release hydrogen peroxide, such as _{polyvinylpyrrolidone} / _H₂O₂ and other polymeric complexes described in US patents 5,008,093, 3,376,110, and 5,183,901; and/or oxidases that produce hydrogen peroxide, such as glucose oxidase or uricase. In all cases here, the term "hydrogen peroxide" is intended to include hydrogen peroxide-generating agents unless expressly stated otherwise. In some embodiments, however, only hydrogen peroxide is used and the compositions do not contain any other hydrogen peroxide-generating agents.

Hair treatment compositions may include up to about 10% hydrogen peroxide, such as about 1% to about 8%, about 1.5% to about 6%, about 4%, or about 2.5% to about 3.5% by weight, relative to the total weight of the composition. For example, hair treatment compositions may contain hydrogen peroxide in amounts ranging from approximately 0.1% to approximately 10%, from approximately 0.1% to approximately 9%, from approximately 0.1% to approximately 8%, from approximately 0.1% to approximately 7%, from approximately 0.1% to approximately 6%, from approximately 0.1% to approximately 5%, from approximately 0.1% to approximately 4%, from approximately 0.1% to approximately 3%, from approximately 0.1% to approximately 2%, from approximately 0.1% to approximately 1%, from approximately 0.5% to approximately 10%, from approximately 0.5% to approximately 9%, from approximately 0.5% to approximately 8%, from approximately 0.5% to approximately 7%, from approximately 0.5% to approximately 6%, from approximately 0.5% to approximately 5%, from approximately 0.5% to approximately 4%, from approximately 0.5% to approximately 3%, from approximately 0.5% to approximately 2%, from approximately 0.5% to approximately 1%, from approximately 1% to approximately 10%, from approximately 1% to approximately 9%, from approximately 1% to approximately 8%, from approximately 1% to approximately 7%, from approximately 1% to approximately 6%, from approximately 1% to approximately 5%, from approximately 1% to approximately 4%, from approximately 1% to approximately 3%, from approximately 1% to approximately 2%, from approximately 1.5% to approximately 10%, from approximately 1.5% to approximately 9%, from approximately 1.5% to approximately 8%, from approximately 1.5% to approximately 7%, from approximately 1.5% to approximately 6%, from approximately 1.5% to approximately 5%, from approximately 1.5% to approximately 4%, from approximately 1.5% to approximately 3%, from approximately 1.5% to approximately 2%, from approximately 2% to approximately 10%, from approximately 2% to approximately 9%, from approximately 2% to approximately 8%, from approximately 2% to approximately 7%, from approximately 2% to approximately 6%, from approximately 2% to approximately 5%, from approximately 2% to approximately 4%, from approximately 2% to approximately 3%, from approximately 2.5% to approximately 10%, from approximately 2.5% to approximately 9%, from approximately 2.5% to approximately 8%, from approximately 2.5% to approximately 7%, from approximately 2.5% to approximately 6%, from approximately 2.5% to approximately 5%, from approximately 2.5% to approximately 4%, from approximately 2.5% to approximately 3%, from approximately 3% to approximately 10%, from approximately 3% to approximately 9%, from approximately 3% to approximately 8%, from approximately 3% to approximately 7%, from approximately 3% to approximately 6%, from approximately 3% to approximately 5%, from approximately 3% to approximately 4%, from approximately 3.5% to approximately 10%, from approximately 3.5% to approximately 9%, from approximately 3.5% to approximately 8%, from approximately 3.5% to approximately 7%, from approximately 3.5% to approximately 6%, from approximately 3.5% to approximately 5%, from approximately 3.5% to approximately 4%, from approximately 4% to approximately 10%, from approximately 4% to approximately 9%, from approximately 4% to approximately 8%, from approximately 4% to approximately 7%, from approximately 4% to approximately 6%, from approximately 4% to approximately 5%, from approximately 4.5% to approximately 10%, from approximately 4.5% to approximately 9%, from approximately 4.5% to approximately 8%, from approximately 4.5% to approximately 7%, from about 4.5% to about 6%, from about 4.5% to about 5%, from about 5% to about 10%, from about 5% to about 9%, from about 5% to about 8%, from about 5% to about 7%, from about 5% to about 6%, from about 5.5% to about 10%, from about 5.5% to about 9%, from about 5.5% to about 8%, from about 5.5% to about 7%, from about 5.5% to about 6%, from about 6% to about 10%, from about 6% to about 9%, from about 6% to about 8%, or about 6% to about 7% by weight, relative to the total weight of the composition. In various embodiments, the compositions may include approximately 0.5%, approximately 0.75%, approximately 1%, approximately 1.25%, approximately 1.5%, approximately 1.75%, approximately 2%, approximately 2.25%, approximately 2.5%, approximately 2.75%, approximately 3%, approximately 3.25%, approximately 3.5%, approximately 3.75%, approximately 4%, approximately 4.25%, approximately 4.5%, approximately 4.75%, approximately 5%, approximately 5.25%, approximately 5.5%, approximately 5.75%, approximately 6%, approximately 6.25%, approximately 6.5%, approximately 6.75%, approximately 7%, approximately 7.25%, approximately 7.5%, approximately 7.75%, approximately 8% of hydrogen peroxide by weight, relative to the total weight of the composition, including all ranges and subranges using any of the preceding values as a lower or upper limit.

In other embodiments, it may be particularly advantageous for the compositions to contain not more than about 8%, such as not more than about 7%, not more than about 6%, or not more than about 5% hydrogen peroxide by weight, relative to the total weight of the composition.

Although not required, it may be useful in some embodiments to include at least one hydrogen peroxide stabilizer, for example, at least one phosphate compound such as tetrasodium etidronate or tetrasodium pyrophosphate, and/or sodium salicylate. If present, hydrogen peroxide stabilizers are typically present in amounts less than about 1%; they may, for example, be included in amounts ranging from about 0.01% to about 0.75% by weight, relative to the total weight of the composition.

In addition to hydrogen peroxide, hair treatment compositions may include additional components such as surfactants, silicones, fatty compounds other than silicones and/or polymers, which have been shown to confer stability to the compositions and/or offer cosmetic benefits to the treated hair.

Hair treatment compositions according to the disclosure may include one or more surfactants, although in at least some embodiments, the compositions may be free of or substantially free of surfactants. Useful surfactants include cationic, anionic, nonionic, and amphoteric surfactants. Without intending to be limited by theory, surfactants, particularly anionic and/or nonionic surfactants, surprisingly impart stability to the compositions in the presence of hydrogen peroxide. In some preferred embodiments, the hair treatment compositions include at least one surfactant selected from anionic and/or nonionic surfactants. In other preferred embodiments, the hair treatment compositions include at least one anionic surfactant and at least one nonionic surfactant.

In various embodiments, the total amount of surfactants may be up to about 15%, such as from about 0.01% to about 15%, from about 0.1% to about 12%, from about 0.5% to about 10%, or from about 1% to about 8% by weight, relative to the total weight of the composition.

These components may include, but are not limited to, dyes/pigments for coloring the composition, film-forming agents, humectants, fillers, structuring agents, propellants, hydrogen peroxide stabilizers, antioxidants or reducing agents, penetrants, sequestrants, perfumes, buffers, dispersants, ceramides, vitamins (e.g., tocopherol), preservatives, opacifiers, sunscreens, and antistatic agents, although it is understood that the composition may be free from, or substantially free from, any of the foregoing.

In various embodiments, the additional components may each be present in the hair treatment compositions in an amount ranging from about 0.001% to about 10%, such as from about 0.01% to about 5%, from about 0.01% to about 4%, from about 0.01% to about 3%, from about 0.01% to about 2%, from about 0.01% to about 1%, from about 0.01% to about 0.75%, from about 0.01% to about 0.5%, from about 0.01% to about 0.4%, from about 0.01% to about 0.3%, from about 0.01% to about 0.2%, from about 0.01% to about 0.1% by weight, relative to the total weight of the hair treatment composition. For example, in some embodiments, the compositions may include at least one hydrogen peroxide stabilizer, wherein the total amount of hydrogen peroxide stabilizers ranges from about 0.001% to about 10%, preferably from about 0.01% to about 5%, more preferably from about 0.01% to about 3%, more preferably still from about 0.01% to about 1.5%, most preferably from about 0.01% to about 1% by weight, relative to the total weight of the composition. As a further example, compositions may include at least one antioxidant, in which the total amount of antioxidants ranges from about 0.001% to about 10%, preferably from about 0.01% to about 5%, more preferably from about 0.01% to about 3%, more preferably still from about 0.01% to about 1.5%, most preferably from about 0.01% to about 1% by weight, relative to the total weight of the composition.

Hair treatment compositions according to the disclosure may be in any form, but are advantageously in the form of a cream, gel, cream-gel, emulsion, or lotion. In various embodiments, the compositions may have a viscosity ranging from approximately 1000 mPa·s to approximately 5000 mPa·s, such as from approximately 2000 mPa·s to approximately 4000 mPa·s, from approximately 2500 mPa·s to approximately 3750 mPa·s, from approximately 2750 mPa·s to approximately 3500 mPa·s, or from approximately 3000 mPa·s to approximately 3250 mPa·s, when measured at 25 °C, 200 rpm for 30 seconds using an M3 spindle (Rheomat 180).

In preferred embodiments, hair treatment compositions are compositions for imparting shine (and optionally non-permanent color) to hair. For example, hair treatment compositions may be compositions for imparting shine (and optionally non-permanent color) to hair that has been previously dyed or bleached. Furthermore, hair treatment compositions are in "ready-to-use" or "all-in-one" form, meaning they do not need to be mixed with a separate composition before use. Ready-to-use compositions are remarkably stable over time, even though they contain hydrogen peroxide, in that they exhibit no change or minimal change in viscosity and/or degradation of hydrogen peroxide for at least one day (24 hours), at least two days (48 hours), at least three days (72 hours), at least one week, at least two weeks, at least four weeks, at least eight weeks, or even at least six months when stored at 4°C, 25°C, 37°C, or 45°C. For example, a hair treatment composition may exhibit less than 10%, such as less than 8%, less than 5%, or even less than 3% change in hydrogen peroxide content and/or viscosity (measured at 25°C, 200 rpm for 30 seconds using an M3 spindle (Rheomat 180)) when stored at a particular temperature for a particular period of time.

II. Processes

The disclosure also concerns methods of using the compositions described herein to treat hair by applying the compositions to the hair. Hair treated with the compositions demonstrates remarkable shine, revitalization, smooth texture, strength, improved detangling and combability, less frizz, and/or appears and is healthier than hair not treated with the compositions.

Hair treatment compositions can be applied to wet, damp, or dry hair. In some embodiments, it is preferable to apply the composition to dry or substantially dry hair, and in other embodiments, it is preferable to apply the composition to wet or damp hair. For example, it may be particularly beneficial to apply hair treatment compositions to hair that has recently been chemically reshaped (e.g., by straightening or perming), lightened, highlighted, and/or dyed. For example, a salon service where hair is chemically reshaped, lightened, highlighted, and/or dyed may include a subsequent step of applying a hair treatment composition to the hair during the same visit. For example, hair may be treated with a hair treatment composition as disclosed within approximately 6 hours or less, such as approximately 4 hours or less, approximately 2 hours or less, approximately 1 hour or less, or approximately 30 minutes or less, after a chemical remodeling, lightening, and/or dyeing service.

In some embodiments, the hair may be treated with a composition that imparts alkalinity to the hair immediately or substantially immediately before being treated with a composition according to the disclosure. Thus, in some embodiments, the hair to which a hair treatment composition is applied is alkaline. Such treatment can be advantageous both for lowering the pH of the hair and for imparting shine (and optionally non-permanent color). By way of non-limiting example, the hair may have undergone a chemical treatment such as a bleaching, oxidative dyeing, perming, straightening, and/or smoothing process, and optionally rinsed, immediately or substantially immediately before the application of a composition according to the disclosure to the hair. In such embodiments, the prior chemical treatment process would be understood as leaving the hair in an alkaline state, even after the chemical treatment composition has been rinsed from the hair. However, since hair treatment compositions according to the disclosure are generally acidic, an alkaline hair treatment with such hair treatment compositions has the benefit of lowering the pH of the hair, while simultaneously imparting shine (and optionally non-permanent color) to the hair.

Without intending to limit ourselves to theory, it is believed that such a hair treatment process can also be beneficial when certain direct dyes are included in the hair treatment composition, for example, those that impart different colors at different pH values (e.g., dyes that are considered acid-base indicators), in order to achieve a desired hair color. As a non-limiting example, tetrabromophenol blue is known to impart a yellow color below a pH of approximately 4.5–4.6, and a blue color above this value. Therefore, if a blue hair color is desired, a hair treatment composition as disclosed, containing tetrabromophenol blue, can be applied to alkaline hair.

As another example, a treatment with a disclosed composition can be a separate, standalone treatment that a consumer may seek to "refresh" the appearance of their hair between chemical reshaping, lightening, and/or coloring services. For example, hair may be treated with a disclosed hair treatment composition more than approximately 24 hours, such as more than approximately 48 hours, more than approximately 72 hours, more than approximately one week, more than approximately two weeks, or more than approximately one month after such a chemical reshaping, lightening, and/or oxidative coloring service. Such treatments can give hair a shiny and healthy look and/or feel, even though it has undergone one or more harsh chemical treatments.

In some embodiments, the hair treatment composition can be applied to wet hair, for example, hair that has just been washed and/or rinsed. However, it should be understood that the hair treatment compositions disclosed herein are not cleansing compositions; that is, the compositions are not shampoos, and the processes are not hair cleansing processes.

The compositions listed in the disclosure are generally considered rinse-out compositions; however, it should be understood that any method of removing the composition from the treated hair is considered. Thus, the composition can be removed from the treated hair after a desired processing time; for example, the hair can be rinsed with water.

A particularly striking aspect of the disclosure is that the processing time required to impart the described benefits to treated hair is generally less than that required for other conditioning, shine-enhancing, and other such compositions. For example, while the processing time required for similar compositions is typically 15 or 20 minutes, the compositions disclosed impart the same or even better properties to hair in approximately 10 minutes or less, such as approximately 5 minutes or less. Therefore, the processes disclosed may include processing times of less than 20 minutes, such as at least approximately 15 seconds, such as at least approximately 30 seconds or at least approximately 1 minute, to less than approximately 15 minutes, such as less than approximately 12 minutes, less than approximately 10 minutes, less than approximately 8 minutes, less than approximately 6 minutes, such as no more than approximately 5 minutes. In preferred embodiments, the exposure time is less than about 15 minutes, for example it may range from about 1 minute to about 15 minutes, from about 2 minutes to about 12 minutes, from about 5 minutes to about 10 minutes, from about 1 minute to about 10 minutes, from about 1 minute to about 8 minutes, from about 1 minute to about 5 minutes, from about 2 minutes to about 10 minutes, from about 2 minutes to about 8 minutes, from about 2 minutes to about 5 minutes, from about 3 minutes to about 10 minutes, from about 3 minutes to about 8 minutes, or from about 3 minutes to about 5 minutes.

In various embodiments, the disclosure relates to hair treatment processes, processes for adding shine to hair, processes for improving the appearance and/or feel of hair, processes for improving the ease of detangling and/or combing hair, processes for reducing the occurrence of split ends, and/or processes for non-permanently altering hair color, comprising applying an effective amount of a composition according to the disclosure to the hair and leaving the composition on the hair for a processing time ranging from at least about 15 seconds such as at least about 30 seconds or at least about 1 minute to about 15 minutes, from at least about 15 seconds such as at least about 30 seconds or at least about 1 minute to about 12 minutes, from at least about 15 seconds such as at least about 30 seconds or at least about 1 minute to about 10 minutes, from at least about 15 seconds such as at least about 30 seconds or at least about 1 minute to about 8 minutes, of at least about 15 seconds such as at least about 30 seconds or at least about 1 minute to about 5 minutes, of about 2 minutes to about 15 minutes, of about 2 minutes to about 12 minutes, of about 2 minutes to about 10 minutes, of about 2 minutes to about 8 minutes, or of about 2 minutes to about 5 minutes, or for about 30 seconds, for about 1 minute, for about 2 minutes, for about 3 minutes, for about 4 minutes, for about 5 minutes, for about 6 minutes, for about 7 minutes, for about 8 minutes, for about 9 minutes, or for about 10 minutes, and then the removal of the hair composition, for example by rinsing the hair.

Such a reduced processing time is considered particularly advantageous because it can reduce or minimize hair damage caused by the treatment process, as well as minimize any unintentional lightening of hair color resulting from the process. Thus, in certain embodiments as disclosed, the processes described are those that do not visibly lighten or enhance hair color.

III. Necessary

The disclosure also relates to necessities. Necessities according to the disclosure include at least one, such as at least two, compartments or containers, and optionally also include instructions.

In various embodiments, a first compartment or container comprises hydrogen peroxide or a hydrogen peroxide-generating agent, preferably in a solvent such as water, and a second compartment or container comprises a composition as described herein other than hydrogen peroxide or the hydrogen peroxide-generating agent. For example, a second compartment or container may comprise a composition including at least one surfactant selected from anionic and/or nonionic surfactants, at least one silicone compound, at least one non-silicone fatty compound, optionally at least one polymer, optionally at least one hydrogen peroxide-stabilizing compound, optionally at least one antioxidant, optionally at least one amino acid and/or aminosulfonic acid, and at least one solvent.

In other embodiments, a first compartment or container comprises a hair care or treatment composition such as a shampoo or conditioner composition, and a second compartment or container comprises a composition as described herein.

Kits can take any form and include any type of compartment or container. For example, a useful kit might be a dual-chamber device configured to dispense different quantities of composition from each chamber upon activation. Other useful kits might include light bulbs. It's important to understand that the types of kits are not limited.

After describing in detail the numerous embodiments of the present invention, it will become apparent that modifications and variations are possible without departing from the scope of the disclosure defined in the appended claims. Furthermore, it should be noted that all the examples in this disclosure, while illustrating numerous embodiments of the disclosure, are provided as non-limiting examples and should therefore not be considered as limiting the various aspects thus illustrated. It should be understood that all definitions herein are provided only for this disclosure.

In this application, the use of the singular includes the plural, unless specifically stated otherwise. The singular forms "a," "an," "the," "the," and "at least one" are understood to encompass both the plural and the singular, unless the context clearly indicates otherwise. The expression "one or more" means "at least one" and therefore includes individual components as well as mixtures/combinations. Similarly, the expression "one of their salts" also refers to "their salts." Thus, when the disclosure refers to "an element chosen from the group consisting of A, B, C, D, E, F, one of their salts or mixtures thereof", it indicates that one or more elements from A, B, C, D and F may be included, that one or more salts from a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included, or that a mixture of any two elements from A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included.

The expression "and/or" should be understood as including both the conjunctive and the disjunctive. For example, "amino acids and/or their salts" means "amino acids and their salts" as well as "amino acids or their salts," and expressly covers either one.

As used here, the term “salts” throughout this disclosure may include salts having a counterion such as an alkali metal, an alkaline earth metal, or an ammonium counterion. This list of counterions, however, is not exhaustive. Salts also include a dissociated form of a compound, for example, in an aqueous solution.

As used herein, the expressions "and mixtures thereof," "and mixtures of two or more of these," "and one of their mixtures," "and their combinations," "and one of their combinations," "or their mixtures," "or one of their mixtures," "or their combinations," and similar expressions are used interchangeably to indicate that the list of components immediately preceding the expression, such as "A, B, C, D, or their mixtures," means that the component(s) can be chosen from A, B, C, D, from A + B, from A + B + C, from A + D, from A + C + D, etc., without limitation on their variations. Thus, the components can be used individually or in any of their combinations.

For the purposes of this disclosure, it should be noted that, for the sake of brevity, some of the quantitative expressions given here are not qualified with the term "approximately." It is understood that, whether the term "approximately" is used explicitly or implicitly, each quantity given here is intended to refer to the actual value given, and also to refer to the approximation of that value that would be reasonably deduced based on ordinary technical skills, including approximations due to experimental and/or measurement conditions for that value, unless otherwise stated.

All ranges and quantities stated herein are assumed to include subranges and quantities using any disclosed point as a boundary, and all boundaries are assumed to be included unless expressly stated otherwise. Thus, a range of "1% to 10%, such as 2% to 8%, such as 3% to 5%" is assumed to encompass ranges of "1% to 8%", "1% to 5%", "2% to 10%", and so on. All numbers, quantities, ranges, etc., are assumed to be modified by the term "approximately", whether or not it is expressly stated, unless expressly stated otherwise. Similarly, a given range of "approximately 1% to 10%" is assumed to have its boundaries of both 1% and 10% modified by the term "approximately". The term "approximately" is used here to indicate a difference of up to +/- 10% from the stated number, such as +/- 9%, +/- 8%, +/- 7%, +/- 6%, +/- 5%, +/- 4%, +/- 3%, +/- 2%, or +/- 1%. Similarly, all range boundaries are understood to be disclosed individually, such that, for example, a range of 1:2 to 2:1 is understood to disclose both a 1:2 and a 2:1 ratio.

As used here, if a component is described as being present "in an amount less than or equal to" a certain amount, it is expected that this component is actually present in the composition, i.e., present in an amount greater than 0%.

All quantities indicated here are relative to the quantity of active ingredient, unless otherwise stated.

All percentages, parts and ratios herein are based on the total weight of the compositions in this disclosure, unless otherwise stated.

As used here, the phrase "applying a composition to the hair," and its variations, is intended to refer to bringing the hair into contact with at least one of the compositions in the disclosure, in any manner whatsoever. It may also refer to bringing the hair into contact with an effective quantity.

“Revitalization,” as used here, means imparting to one or more hair fibers at least one property selected from among combability, moisture retention, luster, shine, and/or softness. The state of revitalization may be assessed by any means known in the art, such as, for example, measuring and comparing the combability of treated and untreated hair in terms of combing work (gm-in) and/or by consumer perception.

A "non-permanent" hair coloring composition or process as described here is meant to refer to a composition or process that does not employ oxidative hair dyes to change hair color.

The term "treat" (and its grammatical variations) as used herein refers to the application of the compositions of this disclosure to the surface of the hair. The term "treat" (and its grammatical variations) as used herein also refers to bringing the hair into contact with the compositions of this disclosure.

A "rinse-out" product refers to a composition, such as a hair treatment, that is removed from the hair after a processing time, for example, by rinsing and/or washing with water. At least a portion, and usually most, of the composition is removed from the hair.

The term "stable" as used here means that the composition does not exhibit more than 10% change in hydrogen peroxide content and/or viscosity (measured at 25°C, 200 rpm for 30 seconds using an M3 spindle (Rheomat 180)) when stored at 25°C for a specified period of time.

“Volatile”, as used here, means having a flash point below about 100 °C.

“Non-volatile”, as used here, means having a flash point above approximately 100°C.

As used here, all provided ranges are intended to include each specific range within the given ranges, as well as a combination of intermediate sub-ranges. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as sub-ranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc.

Unless otherwise defined for any specific embodiment, the expression "substantially free" or "essentially free" as used herein means that there is less than approximately 5% by weight of a specific material added to a composition, relative to the total weight of the composition. For example, compositions may include less than approximately 4%, less than approximately 3%, less than approximately 2%, less than approximately 1.5%, less than approximately 1%, less than approximately 0.5%, less than approximately 0.1%, less than approximately 0.01%, less than approximately 0.001%, or less than approximately 0.0001% of the specified material. As such, it is envisaged that any component described herein for use in hair treatment compositions may be present in the compositions in amounts less than approximately 5%, less than approximately 4%, less than approximately 3%, less than approximately 2%, less than approximately 1%, less than approximately 0.5%, less than approximately 0.1%, less than approximately 0.01%, less than approximately 0.001%, or less than approximately 0.0001%, and the composition will be considered "substantially free" of such material. A composition "free" of a component is understood to contain none of the specified components. However, it is understood that the terms "free" and "substantially free" refer to the amount of a component added to the composition, without including an amount of the component present in the composition as a minor component in a raw material. For example, a "wax-free" composition may not have wax included as an intended component, but may nevertheless contain a pigment that is coated with a wax, since such a wax would be considered a minor component of the pigment material and should not provide benefits to the composition that would be expected from including a wax itself as an intended component.

Unless expressly stated otherwise, no process described herein is intended to be interpreted as requiring its steps to be performed in a specific order. Consequently, where a process claim does not expressly specify an order for its steps, or where the claims or descriptions do not specifically state that the steps must be limited to a specific order, no particular order is to be inferred.

The following examples are intended to illustrate embodiments of this disclosure but are not exhaustive. It will be obvious to those skilled in the art that various modifications and variations can be made to the compositions and processes of the invention without departing from the spirit or scope of the invention. Therefore, this disclosure is intended to cover modifications and variations that fall within the scope of the attached claims and their equivalents.

EXAMPLES

The following examples are intended to be non-explanatory and non-limiting. In the Examples, unless otherwise stated, quantities are expressed as a percentage by weight (% by weight) of active ingredients, relative to the total weight of the composition.

TABLE 1-3

Example 2 – Evaluation of shine and revitalization performance

The following half-head studies were conducted by a panel of experts using volunteers with previously bleached and/or colored hair.

Example 2A – Comparative studies Shine and cosmetic benefits

Three comparative studies were conducted comparing a commercially available shine treatment with hair treatment compositions as disclosed. First, the hair of all volunteers was shampooed, rinsed, and towel-dried. Then, composition C1, a commercially available hair shine product, was mixed with an aqueous 6.7V hydrogen peroxide developer to provide a mixture ( _mixture C1) containing 1% hydrogen peroxide and having a pH of approximately 6.5.

Study protocols

Study 1: On three volunteers, half of their hair was treated with composition 1A and the other half with _mixture C1. Equal amounts of each composition were applied to each half of the hair, massaged into the hair to coat it, and left to act. The hair treated with composition 1A was rinsed after 5 minutes, while the hair treated with _mixture C1 was rinsed after 20 minutes, according to the product instructions. The hair was then dried with a hairdryer.

Study 2: On three additional volunteers, half of their hair was treated with composition 1A and the other half with _mixture C1. Equal amounts of each composition were applied to each half of the hair, massaged in to coat the hair, and left to act. Each volunteer's hair was rinsed after 5 minutes and then dried with a hairdryer.

Study 3: On two additional volunteers, one half of the hair was treated with composition 1E and the other half with _mixture C1. Equal amounts of the respective compositions were applied to each half of the hair, massaged into the hair to coat it, and left to act on the hair. The hair treated with composition 1E was rinsed after 5 minutes, while the hair treated with _mixture C1 was rinsed after 20 minutes. The hair was then dried with a hairdryer.

Results

Experts evaluated the properties and feel of the hair while wet, during the drying process, and once dry. They concluded that hair treated with formulations 1A and 1E was ranked at the same level as, or better than, hair treated with formulation C1 for its wet detangling/ _combing properties, wet elasticity, dry combability, dry smoothness, dry shine, dry frizz control, and hydrated feel with reduced appearance of split ends on dry hair. This was observed both when _formulation C1 was rinsed out after 20 minutes, as indicated on the packaging (Study 1), and after 5 minutes (Study 2). It was noted, for example, that in study 2, hair treated with composition 1A exhibited significantly better combability and manageability with a shinier and smoother appearance than hair treated for the same duration with composition C1 _mixture .

Furthermore, experts observed that hair treated with compositions 1A and 1E was rated at the same level or better than hair treated with composition C1 _mixture for shine. This was also observed both when composition C1 _mixture was rinsed after 20 minutes, as indicated on the packaging (Study 1), and after 5 minutes (Study 2). For example, in Study 2, hair treated with composition 1A had significantly more shine (a score of 5 out of 6) than hair treated for the same duration with composition C1 _mixture (a score of 2.5 out of 6).

Example 2B – Additional Gloss Study

A further study was conducted to evaluate the effectiveness of hair treatment compositions containing hydrogen peroxide in imparting shine to hair. The compositions tested were identical except for the amount of hydrogen peroxide they contained.

On two volunteers, one half of the hair was treated with composition 1I (1% hydrogen peroxide) or 1J (3% hydrogen peroxide), and the other half with composition C2 (no hydrogen peroxide). Equal amounts of the respective compositions were applied to each half of the hair, massaged into the hair to coat it, and left on for 5 minutes before rinsing thoroughly. The hair was then dried with a hairdryer.

Once the hair was dry, the experts assessed it in terms of shine. They concluded that hair treated with formula 1J had the greatest shine, followed by hair treated with formula 1I, while hair treated with formula C2 showed no appreciable shine compared to hair before treatment.

The results of these studies demonstrate that hydrogen peroxide surprisingly provides noticeable cosmetic benefits and shine to hair when treated with the compositions and processes disclosed. Surprisingly, hair color was not lightened in these studies, even with higher concentrations of hydrogen peroxide.

Example 3 – Stability studies

To assess the stability of the compositions as disclosed, the following studies were conducted. Compositions 3A and 3B were prepared as indicated in Table 3-1 and evaluated in terms of viscosity and hydrogen peroxide content.

TABLE 3-3 – Hydrogen peroxide content (%)

The stability studies in Tables 3-2 and 3-3 show that the hair treatment compositions disclosed are remarkably stable over extended periods, as demonstrated by what is considered minimal variation in viscosity and hydrogen peroxide content. The observed variations are considered to be within acceptable tolerances.

The results of the stability studies therefore demonstrate that hair treatment compositions containing silicone compounds, non-silicone fatty compounds and a combination of anionic and non-ionic surfactants offer surprisingly stable compositions despite the presence of hydrogen peroxide, even in the absence of hydrogen peroxide stabilizers.

TABLE 4-2

Compositions 4F and 4G should also provide beneficial effects such as shine, softness, ease of combing/detangling, smooth texture, frizz reduction, etc., to the hair, while simultaneously providing non-permanent hair color.

In addition, compositions 4E, 4F and 4G can be applied to hair that is alkaline in order to impart a blue or purple color to the hair.

The data above demonstrates that the disclosed compositions provide unexpected and beneficial cosmetic effects on hair, such as shine, softness, manageability/detangling, frizz reduction, etc., and require surprisingly less processing time to achieve these benefits. Furthermore, the hair treatment compositions are remarkably stable despite the presence of hydrogen peroxide.
