This patent application claims priority from U.S. non-provisional application No.17/003,558, filed 8/26 in 2020, the entire contents of which are incorporated herein by reference.

Technical Field

The present disclosure relates to compositions and methods for treating hair, kits comprising the compositions, and methods of using the compositions.

Background

Consumers often use cosmetic care compositions to improve, treat or alter the appearance of keratin substrates such as hair, for example, by altering the color, style and/or shape of the hair, and/or by imparting various characteristics to the hair, such as shine and conditioning. Many known compositions and methods for improving the appearance of hair involve chemical treatment of the hair.

For example, one such chemical treatment of hair involves changing color. This may involve removing color and/or depositing artificial pigments onto the hair to provide a different shade or color, and/or boosting (lift) the color of the hair during lightening of deeper hair to a brighter shade. Methods of enhancing (also known as lightening) hair color generally require the use of compositions having at least one oxidizing agent. The change in tone (tone) height before and after application of the hair color changing composition was used to evaluate the lightening or boosting of hair color. The degree or level of highlighting or lifting corresponds to a change. The concept of "hue" is based on the classification of natural chromaticities, one hue separating each chromaticity from the immediately following or immediately preceding chromaticity, as is well known to hair styling professionals. The height or level of the tone ranges from 1 (black) to 10 (light gold), one unit corresponding to one tone. Thus, the larger the number, the brighter the chromaticity or the greater the degree of lifting.

Hair lightening or colour enhancing compositions and hair colouring compositions are typically alkaline, have a pH above 7, and typically have a pH above 9. It is generally desirable to present an alkalizing agent such as ammonia or an ammonia generating compound and/or an amine or ammonium based compound in an amount sufficient to render such compositions alkaline. The alkalizing agent swells the hair shaft, allowing small oxidative dye molecules to penetrate the cuticle and cortex of the hair before the oxidative condensation process is completed. The larger-sized colored complex produced by the oxidation reaction is then trapped within the hair fibers, permanently changing the color of the hair.

In addition, there are many techniques and compositions for styling or changing hair shapes. For example, hair care products known as "hair softeners" or "hair straighteners (hair straightener)" can soften or straighten curly (curl) or curved (king) hair, including wavy hair. Straightening or softening a very curly hair roll can increase the manageability and ease of styling of such hair. The long acting hair curling composition will impart curls or waves to the otherwise straight hair. To alter the shape of the hair and make it easier to treat, different types of compositions (e.g., alkaline and acidic compositions) may be applied to the hair. The hair softener, straightener, permanent wave (perm) and/or hair curler (wave) may be applied at the hair salon by a professional or at home by an individual consumer.

These chemical treatments can damage hair fibers and/or irritate the scalp during dyeing and/or lightening, softening, straightening, perming and/or curling. Thus, in order to reduce or avoid damaging the hair, as well as to improve the cosmetic properties of the compositions, it is continually sought to use new additional components and/or new combinations of ingredients.

Various compositions have been provided, and so far, selection of components or combinations of ingredients often poses difficulties because they are often unstable, detrimental to other properties of the cosmetic product, and/or present other problems. For example, many of the compositions used heretofore lack ease and uniformity of application and/or have poor rheology, viscosity, stability, color deposition, and/or target chromaticity formation. As a result, these compositions create more drawbacks and in many cases lead to increased damage to hair and/or appear unhealthy. It is therefore desirable to provide consumers with compositions and methods that can treat hair, such as to enhance the color of and/or deposit color onto hair in an efficient manner, while providing other cosmetic benefits to the hair, such as shine, conditioning, fiber strength, and/or a healthy appearance, but avoiding or minimizing damage to the hair.

Furthermore, typically natural and sensitized and/or chemically treated hair may contain several negatively charged moieties, such as carboxylate (resulting from hydrolysis of amino acid and thioester bonds) and/or sulfonate (resulting from oxidation of disulfide bonds). These negatively charged portions reduce the cosmetic properties of the hair. Furthermore, when the hair is chemically treated or damaged, disulfide bonds (disulfide bonds between two cysteine units) in the hair may be reduced or broken, resulting in the formation of thiol groups and/or cysteines.

Accordingly, there is a need in the art for new compositions that protect hair fibers during bleaching to reduce damage to hair or further damage. There is also a need in the art for compositions that impart cosmetic improvements to bleached hair and have improved feel, such as tough, enhanced softness, shine, conditioning and healthy appearance, during dyeing, lightening, straightening, softening and/or styling.

Disclosure of Invention

The present disclosure relates to compositions and methods for reducing damage to hair fibers during bleaching, while also providing treatment and cosmetic improvement of hair fibers compared to traditional post-bleaching feel (post-bleaching feel) of hair fibers. Uniquely, the subject compositions and methods provide stable compositions having inherent antioxidant and adhesive properties that significantly improve hair quality and durability during hair lightening. As a result of the use of the subject compositions, damage in chemical treatments (lightening/bleaching processes) is minimized and/or treated, it has been found that the compositions protect the keratin fibers of hair.

The subject compositions use one or more antioxidants (having aromatic rings with two alcohol functionalities, preferably baicalin) in combination with polycarboxylic acids and amino acids built into the hair lightening composition to provide built-in bleaching systems that reduce damage to hair. Surprisingly and unexpectedly, it has been found that an antioxidant having an aromatic ring with two alcohol groups in combination with a polycarboxylic acid and an amino acid is stable in powder form when mixed with a bleach powder/hair color changing agent/brightening agent, providing an in-situ one-step bleaching process. Furthermore, it has surprisingly and unexpectedly been found that one or more combinations of antioxidants having aromatic rings with two alcohol functionalities, polycarboxylic acids and amino acid combinations provide significant benefits to fiber integrity during hair bleaching, increasing tensile strength, elastic modulus and reducing citric acid formation compared to the same bleach without the desired combination. Furthermore, the subject compositions have been found to provide durable smoothness and manageability to hair after bleaching, which, based on information and confidence, is directly related to the synergistic effect of the two alcohol functional aromatic rings present in the antioxidant in combination with polycarboxylic acids and amino acids.

In various embodiments, the present invention provides compositions and kits that are prepared for various modes of delivery to keratin materials to have one or more of the following efficacy: protecting the keratin materials from oxidizing agents in a color change system; enhancing and protecting one or more organoleptic characteristics of keratin materials treated with an oxidizing agent in a color-changing system; protecting and maintaining the mechanical properties and natural amino acid structure of hair.

The present invention relates to a built-in bleach composition which is a combination of one or more selected antioxidants (having aromatic rings with two alcohol functions) with polycarboxylic acids and amino acids. Non-limiting benefits of the subject built-in bleaching systems include that the antioxidant, polycarboxylic acid and amino acid systems are stable in powder form when mixed with bleach powder, thereby providing a one-step bleaching process. The combination of antioxidants, polycarboxylic acids and amino acids has been found to provide benefits to fiber integrity during hair bleaching, resulting in increased tensile strength and elastic modulus, and reduced formation of citric acid, compared to bleaching compositions that do not contain the novel composition. Furthermore, the subject compositions have been found to provide durable smoothness and manageability to hair after bleaching, which, based on information and confidence, is directly related to the presence of aromatic rings bearing two alcohol functionalities in the antioxidant.

In one embodiment, the antioxidant comprises at least one antioxidant having an aromatic ring with two alcohol functional groups. Preferably, the antioxidant comprises at least one polyphenol selected from baicalin, ferulic acid (ferulic acid), pine bark extract, polydatin or ellagic acid (ellagic acid). Most preferably, the antioxidant may comprise at least one polyphenol having an aromatic ring with two alcohol functions selected from flavonoid glycosides (flavonoid glycoside), optionally comprising baicalin.

Detailed Description

The present disclosure relates to hair protection compositions useful for lightening and/or coloring hair. These compositions are unique in that they reduce damage to hair due to chemical treatment (bleaching). Hair treatment compositions relate to compositions that strengthen hair and/or reduce damage to hair caused by chemical treatments, including bleaching and/or dyeing of hair. The treated hair fibers (hair treated with the composition) have desirable cosmetic properties such as improved gloss, improved combability, and improved strength and elasticity. Successful treatment of hair can be determined, for example, by analysis of the vesicle acid (cystic acid).

The inventors have surprisingly and unexpectedly found that a composition (comprising a combination of one or more polycarboxylic acids, one or more amino acids and one or more antioxidants comprising an aromatic ring having two alcohol functions) is used in combination with a color-changing system (e.g. an oxidative lift or bleaching or dyeing composition) which, when applied to keratin materials such as hair with or without heating, provides protection to the keratin materials from the damaging effects of bleach and/or oxidants in the color-changing system; improving or protecting one or more organoleptic properties and maintaining the mechanical properties and natural amino acid structure of keratin materials treated with bleaching or oxidizing agents in a color-changing system. Thus, the treatment composition of the present invention provides protection to the keratin materials from the damaging effects of bleach and/or oxidizing agents to enhance and protect one or more organoleptic characteristics selected from combability, softness, elasticity, moisture retention and gloss. In some particular examples, the inventors have found that applying a polycarboxylic acid, amino acid and antioxidant (in particular an antioxidant and/or other polyphenol comprising an aromatic ring with two alcohol functions selected from flavonoid glycosides, preferably baicalin) to hair, either before or simultaneously with the application of at least one bleaching agent (oxidation precursor), results in a significant retention of the mechanical properties and organoleptic characteristics of the hair compared to treatment with a color changing system without antioxidant.

Without being bound by any theory, the inventors of the present disclosure believe that the polycarboxylic acid, amino acid and antioxidant compound in the treatment composition of the present invention act synergistically to trap the oxidized species (free radicals) generated in the oxidation reaction to prevent them from binding to the keratin fibres, thereby protecting the keratin materials from damage or minimizing damage to the hair. Thus, while other compositions using acids can effectively lower pH and slow oxidation rates, they lack the benefit of protecting the keratin fibers from damage caused by excess free radicals or minimizing such damage. The compositions of the present invention provide surprising and unexpected protective benefits that are not observed in comparative formulations comprising acids.

The compositions of the present invention are compositions comprising one or more polycarboxylic acids, one or more amino acids and one or more antioxidant compounds, and components of a bleach and/or hair color changing system, including optionally one or more dyes or colorants. The composition may include other suitable ingredients for hair treatment or hair restoration. For example, in addition to polycarboxylic acids, amino acids, and antioxidant compounds, known solvents and/or additives may be used to provide additional benefits to the composition.

The hair treatment compositions of the present disclosure generally comprise:

(a) One or more polycarboxylic acids and/or salts thereof;

(b) One or more amino acids and/or salts thereof; and

(c) One or more antioxidants comprising an aromatic ring with two alcohol functions.

The amounts of the above three components (a) - (c) of the treatment composition may vary and will depend on the other components (and the amounts of the other components), if any, in the hair treatment composition. In general, however, the ratio of the one or more polycarboxylic acids (a) to the one or more amino acids (b) is from about 2:1 to about 10:1, regardless of the other components in the hair treatment composition. Further, the ratio of the one or more polycarboxylic acids (a) to the one or more amino acids (b) may be from about 3:1 to about 9:1, from about 4:1 to about 8:1, or from about 5:1 to about 6:1.

Typically, the ratio of the one or more polycarboxylic acids (a) to the one or more antioxidants (c) is from about 1:1 to about 8:1. However, the ratio of the one or more polycarboxylic acids (a) to the one or more antioxidants (c) may be from about 2:1 to about 7:1, from about 2:1 to about 6:1, from about 2:1 to about 5:1, from about 3:1 to about 7:1, from about 3:1 to about 6:1, from about 3:1 to about 5:1, or from about 3:1 to about 4:1.

Typically, if one or more cationic conditioning agents are present, the ratio of the one or more polycarboxylic acids (a) to the one or more antioxidants (c) is from about 1:1 to about 8:1. However, the ratio of the one or more polycarboxylic acids (a) to the one or more cationic conditioning agents (c) may be from about 2:1 to about 7:1, from about 2:1 to about 6:1, from about 2:1 to about 5:1, from about 3:1 to about 7:1, from about 3:1 to about 6:1, from about 3:1 to about 5:1, or from about 3:1 to about 4:1.

Typically, the ratio of the one or more amino acids (b) to the one or more antioxidants (c) is from about 1:1 to about 1:10. Further, the ratio of the one or more amino acids (b) to the one or more antioxidants (c) may be from about 1:2 to about 1:9, from about 1:4 to about 1:8, or from about 1:5 to about 1:6.

Typically, the ratio of the one or more amino acids (b) to the one or more cationic conditioning agents (c) is from 0.1:1 to about 5:1, if present. However, the ratio of the one or more amino acids (b) to the one or more cationic conditioning agents (c) may be from about 0.1:1 to about 2:1, from about 0.1:1 to about 1:1, from about 0.2:1 to about 3:1, from about 0.2:1 to about 2:1, from about 0.2:1 to about 1:1, from about 0.5:1 to about 3:1, from about 0.5:1 to about 2:1, or from about 0.5:1 to about 1:1.

The present disclosure also relates to hair lightening compositions comprising the above hair treatment composition components. The treatment composition may be added directly to a hair lightening composition to obtain a ready-to-use hair lightening composition. For example, the hair treatment composition may be added to the hair lightening composition, mixed, and the mixture applied to the hair immediately (within 1 to 60 minutes). Alternatively, the hair lightening composition may already comprise the components of the hair treatment composition (without the need for separate packaging and mixing). Accordingly, the present disclosure relates to hair lightening compositions comprising:

(a) One or more polycarboxylic acids and/or salts thereof;

(b) One or more amino acids and/or salts thereof;

(c) One or more antioxidants; and

(d) One or more bleaching agents.

In some cases, the polycarboxylic acid may be selected from the group consisting of maleic acid, malonic acid, citric acid, salts thereof, or mixtures thereof.

The total amount of the one or more polycarboxylic acids and/or salts thereof may vary, but is typically from about 0.1 to about 10 weight percent, based on the total weight of the hair lightening composition. In some cases, the total amount of the one or more polycarboxylic acids and/or salts thereof is from about 0.1 to about 8 wt%, from about 0.1 to about 6 wt%, from about 0.1 to about 5 wt%, from about 0.5 to about 10 wt%, from 0.5 to about 8 wt%, from about 0.5 to about 6 wt%, from about 0.5 to about 5 wt%, from about 1 to about 10 wt%, from about 1 to about 8 wt%, from about 1 to about 6 wt%, or from about 1 to about 5 wt%.

A more detailed, but non-limiting list of components that can be used in the compositions of the present disclosure is shown below.

Antioxidant component

The antioxidant component of the present disclosure is variously included in the compositions of the present invention. The antioxidant component comprises at least one antioxidant compound. Some representative examples of antioxidant compounds include baicalin (baicalin root extract), pine bark extract (coastal pine bark/bud extract), ferulic acid (a hydroxy cinnamic acid), and ellagic acid. Other examples include dihydrochalcones, ascorbic acid, zinc PCA and polydatin. More generally, the antioxidant compound may be selected from among, inter alia, phenolic compounds (including polyphenols).

Phenolic compounds

Phenolic compounds are structural classes of natural, synthetic and semisynthetic organic compounds having one or more phenolic structures. Phenolic compounds containing multiple phenolic groups are known as polyphenols. Polyphenols are often present in plants and are very helpful in protecting plants and animals from common health disorders and aging. The polyphenol functionality acts as a potential radical scavenger by providing its alcohol hydrogen or one of the delocalized electrons. Two classes of polyphenols are flavonoids and non-flavonoids.

Flavonoids are a specific class of polyphenols, the most abundant polyphenolic compounds, accounting for about two-thirds of the total phenols in the feed consumed. Flavonoid compounds can be further classified into chalcones, flavones, flavanones, flavanols, flavonols, flavanols, isoflavones, neoflavones, catechins, anthocyanidins and tannins according to chemical structure. Over 4,000 flavonoids have been identified, many of which are found in fruits, vegetables and beverages (tea, coffee, beer, wine and juice beverages). Flavonoids have been reported to have antiviral, antiallergic, antiplatelet, anti-inflammatory, antitumor and antioxidant activities. Flavonoids protect lipids and important cellular components from oxidative stress (oxidative stress) by effectively scavenging free radicals.

Non-flavonoid polyphenols include lignans, aurones (aurones), stilbenes (stilbenoids), curcumin (curcuminoids) and other phenylpropanoids (phenylpropanoids). Many of these are also well known antioxidants, such as resveratrol (resveratrol), curcumin (curcumin) and pinoresinol (pinoresinol).

In addition to polyphenols, other phenolic compounds include alkylphenols, betaines, capsaicinoids, hydroxybenzoketones, methoxyphenols, naphthoquinones, and phenolic terpenes. Some common examples are ferulic acid, hydroxytyrosol (hydroxytyrosol), cinnamic acid, caffeic acid and p-coumaric acid.

SelectedAntioxidant compounds

According to some embodiments of the present disclosure, the antioxidant compounds include one or more of baicalin (baicalin root extract), pine bark extract (coastal pine bark/bud extract), ferulic acid (a hydroxycinnamic acid), and ellagic acid.

The radix Scutellariae extract comprises baicalin, which is also known as a component of the herb Scutellaria baicalensis, which is a kind of flavone, flavonoid. It is an effective antioxidant and has been shown to have an effective effect on oxidative stress diseases, inflammation, allergies, cancer, bacterial infections, etc.

Pine bark extract (coastal pine bark/bud extract) contains a variety of compounds, including oligomeric procyanidins, and generally has a variety of benefits of cholesterol control, cardiovascular, other circulatory system, and brain benefits.

Ferulic acid is a hydroxycinnamic acid that can be found extensively in seeds of fructus Anisi Stellati, coffee, fructus Mali Pumilae, artichoke, semen Arachidis Hypogaeae and fructus Citri sinensis, and seeds and cell walls of Commelinid plants (such as rice, wheat, oat, and pineapple). As with many natural phenols, it is a strong antioxidant, is very sensitive to free radicals, and reduces oxidative stress. Many studies indicate that ferulic acid may have anti-tumor activity.

Ellagic acid is a small phytochemical that naturally occurs in red fruits and berries and in some nuts, including pomegranates, strawberries, blackberries, raspberries, cranberries, walnuts and hickory nuts. Ellagic acid may also be produced by the decomposition of ellagitannins that are available from certain plants. Ellagic acid has been shown to have anticancer activity as well as other benefits.

An optional Hydrotrope (Hydrotrope)

If the solubility of any of the components in water is low, a hydrotrope or glycol may be used in some embodiments to increase the solubility of the components of the composition. The hydrotrope solution is prepared by completely dissolving one or more hydrotropes in water. The components are then added and mixed using a stirring bar or any other mixer. Dissolution of the components occurs within minutes and mixing continues until a clear stable solution is obtained, typically within one hour after mixing. The method is followed without heating to dissolve the phenolic compound. Everything was prepared at room temperature to maintain the stability of the phenolic compound. This is very useful for protecting the activity of certain compounds and also makes the process easier.

Hydrotropes (or hydrotropes) are a broad class of water-soluble compounds characterized by amphiphilic molecular structures and capable of significantly increasing the solubility of poorly soluble organic molecules in water. The at least one hydrotrope is present in the composition in an amount effective to increase the solubility of the phenolic compound in water. At least one hydrotrope refers to one or a combination of two or more hydrotropes. A combination of one or two or more hydrotropes may be used to increase the solubility of phenolic compounds in water. The amount of hydrotrope will vary depending on the type and amount of hydrotrope and phenolic compound. Increasing the water solubility of a phenolic compound refers to increasing the solubility of the phenolic compound in water compared to the solubility of the phenolic compound in water in the absence of one or more hydrotropes.

One advantage of using a hydrotrope is that once a stable solution is obtained, further dilution does not affect the stability of the solution. This is in contrast to organic solvents that are commonly used to increase the water solubility of phenolic compounds (e.g., polyphenols). In general, aqueous dilution of an organic solvent with a pre-dissolved phenolic compound (e.g., polyphenol) can result in crystallization or precipitation.

Most hydrotropes have aromatic structures with ionic moieties, and some of them are straight alkyl chains, as listed in the following table. Although hydrotropes are significantly similar to surfactants and have the ability to reduce surface tension, their small hydrophobic units and relatively short alkyl chains distinguish them as distinct amphiphiles. Thus, even with high concentrations, their hydrophobicity is insufficient to produce well organized self-assembled structures (self-associated structure), such as micelles.

Common hydrotropic molecules include: sodium 1, 3-benzenedisulfonate, sodium benzoate, sodium 4-pyridinecarboxylate, sodium salicylate, sodium benzenesulfonate, caffeine, sodium p-toluenesulfonate, sodium butyldiglycol sulfate, 4-aminobenzoic acid HCl, sodium cumene sulfonate, N-diethylnicotinamide, N-pyridylmethylamide (picolinimide), N-allylnicotinamide, 2-methacryloyloxyethyl phosphorylcholine, resorcinol, butylurea, pyrogallol, N-pyridylmethylacetamide 3.5, procaine HCl (procaine HCl), proline HCl, nicotinamide, pyridine, 3-pyridylmethylamine, ibuprofen sodium, sodium xylene sulfonate, ethyl carbamate, pyridoxal hydrochloride, sodium benzoate, 2-pyrrolidone, ethylurea, N-dimethylacetamide, N-methylacetamide, and isoniazid. Hydrotropes are found in Lee j et al, "Hydrotropic Solubilization of Paclitaxel: analysis of Chemical Structures for Hydrotropic Property", pharmaceutical Research, volume 20, phase 7 of 2003; and Lee S. et al, "Hydrotropic Polymers: synthesis and Characterization of Polymers Containing Picolylnicotinamide Moieties", macromolecules,36,2248-2255,2003.

Cosmetically acceptable hydrotropes refer to hydrotropes that can be used in cosmetic compositions. Although hydrotropes represent a class of molecules that are widely used in a variety of fields, cosmetic applications will be limited due to safety and tolerability limitations. Suitable hydrotropes for use in cosmetics include, but are not limited to, niacinamide (vitamin B3), caffeine, sodium PCA (sodium salt of pyrrolidone carbonic acid), sodium salicylate, urea, and hydroxyethyl urea. The suitability of a hydrotrope for use in a cosmetic composition may be determined using assays known in the art for determining the effect on skin and toxicity to the human body.

The hydrotrope may be present in the composition in an amount of 0.1% to about 20%; about 0.1% to about 10%; or about 1% to about 5% based on the total weight of the composition.

Water and its preparation method

The antioxidant-containing composition may comprise from about 1 to about 99.9 weight percent water, relative to the total weight of the composition. The amount of water in the composition may be from 1 to 99.5%; about 1 to 60%; or about 1 to 50% based on the total weight of the composition.

pH

The pH of the composition is not limited, but is typically 2 to 12, or 3 to 9. The pH can be adjusted to the desired value by adding a base (organic or inorganic), such as ammonia or a primary, secondary or tertiary (poly) amine, such as monoethanolamine, diethanolamine, triethanolamine, isopropanolamine or 1, 3-propanediamine, to the composition; or the pH is adjusted to the desired value by adding an inorganic or organic acid, advantageously a carboxylic acid, such as citric acid.

Details regarding the preparation of these polymers can be found in U.S. Pat. Nos. 3,288,770, 3,412,019 and 4,772,462, which are incorporated herein by reference. For example, cationic homopolymers and copolymers of polydiallyl dimethyl ammonium chloride are available from the company Calgon Corporation of Merck & co located in pittsburgh, pa under the trademark MERQUAT. A homopolymer named polyquaternium-6 (in CTFA Cosmetic Ingredient Dictionary, third edition, published by Cosmetic Toiletry and Fragrance Association, inc. in 1982 (hereinafter CTFA dictionary and CTFA name)) is sold under the trademark MERQUAT-100 and is described as having a weight average molecular weight of about 100,000. The copolymer reaction product of dimethyldiallylammonium chloride and acrylamide monomer is designated polyquaternium-7 (in the CTFA dictionary) and is described as having a weight average molecular weight of about 500,000 and sold under the trademark MERQUAT-550. Another copolymer reaction product of dimethyldiallylammonium chloride and acrylic acid having a weight average molecular weight of about 50,000 to about 10,000,000 is sold under the CTFA name polyquaternium-22 under the trademark MERQUAT-280. Polyquaternium 6 is particularly preferred.

Other polymeric conditioning agents include cationic copolymers of methyl vinyl imidazole chloride and vinyl pyrrolidone commercially available from BASF Aktiengesellschaft of Germany under the trade name LUVIQUAT in three comonomer ratios (i.e., methyl vinyl imidazole chloride to polyvinyl pyrrolidone ratios of 95/5, 50/50 and 30/70). All three comonomer ratios of these copolymers had CTFA designation polyquaternium 16. Polymeric conditioning agents also include cationic cellulose POLYMERs, such as those sold under the trademark POLYMER JR by Union Carbide Corporation, danbury, conn. At various viscosity grades and molecular sizes, which are obtained by reacting hydroxyethyl cellulose with epichlorohydrin and quaternizing with trimethylamine. These polymer families are designated as polyquaternium 10 in the CTFA dictionary. Also useful are quaternized copolymers of hydroxyethylcellulose and dimethyldimethylammonium chloride having the CTFA name polyquaternium-4 sold under the trademark CELQUAT by National Starch and Chemical Corporation, bridgewater, n.j at different molecular weights.

Smaller molecule cationic non-polymeric conditioning agents may also be used herein. Exemplary small molecule conditioning agents may include monofunctional or difunctional quaternary ammonium compounds such as stearyl dimethylbenzyl ammonium chloride, dimethyl bis- (hydrogenated tallow) ammonium chloride, and the like. Non-polymeric conditioning agents may also include quaternary ammonium salts of glucamide derivatives, such as gamma-glucamide propyldimethyl-2-hydroxyethyl-ammonium chloride and famoxamido propyldimethyl-2-hydroxyethyl-ammonium chloride (minukamidopropyl-2-hydroxyethylammonium chloride) as defined by CTFA names quaternary ammonium salt 22 and quaternary ammonium salt 26, respectively. Details of the preparation of these materials are found in U.S. patent nos. 3,766,267 and 4,012,398, respectively, and are sold under the trade name cepahtl by Van Dyk & co. Also useful are bisquaternary ammonium compounds which are DIMERs, such as 2-hydroxypropyl bis-1, 3- (dimethyl stearylammonium chloride, CTFA designation, hydroxypropyl bisstearyldiammonium chloride.

Exemplary non-quaternized polymers having tertiary amino nitrogen groups that are quaternized when protonated can include water-soluble protein quaternary ammonium compounds. For example, cocohydrolyzed animal protein is the CTFA name, a chemically modified quaternary ammonium derivative of hydrolyzed collagen having about 12 to about 18 carbon atoms in at least one aliphatic alkyl group, a weight average molecular weight of about 2500 to about 12,000, and a plasma point of about 9.5 to about 11.5. The materials and structurally related materials are sold under the trade names CROQUAT and CROTEIN by Croda, inc.

In some aspects, the subject compositions do not comprise a polymeric conditioning agent.

Bleaching agent

The bleaching agent may be selected from, for example, peroxides, persulfates, perborates, percarbonates, alkali metal bromates, ferricyanides, peroxo salts, or mixtures thereof. Bleaching agents that may also be used include at least one oxidoreductase, such as laccase, peroxidase and 2-electron oxidoreductase, such as uricase, where appropriate in the presence of their respective donors or cofactors. Oxygen in the air may also be used as the oxidizing agent.

In some cases, the bleaching agent is a persulfate and/or monopersulfate, such as potassium persulfate, sodium persulfate, ammonium persulfate, and mixtures thereof. In one embodiment, the oxidizing agent in the present disclosure is selected from hydrogen peroxide, potassium persulfate, sodium persulfate, or mixtures thereof.

Color developer

The hair lightening compositions of the present disclosure may be combined with a developer composition. The developer composition is typically an aqueous composition comprising one or more oxidizing agents, such as peroxides. Non-limiting examples of oxidizing agents include those that are water soluble, such as peroxy oxidizing agents. The oxidizing agent may be selected from water-soluble oxidizing agents, which are inorganic peroxide materials capable of generating hydrogen peroxide in aqueous solution.

The oxidizing agent may be provided in the form of an aqueous solution or in the form of a powder (which is dissolved prior to use). Water-soluble oxidizing agents include hydrogen peroxide, inorganic alkali metal peroxides (sodium peroxide ), and organic peroxides (e.g., urea peroxide, melamine peroxide), and inorganic perhydrate bleaching compounds (e.g., alkali metal salts of perborates, percarbonates, perphosphates, persilicates, persulphates, etc.). These inorganic perhydrate salts may be incorporated as monohydrate, tetrahydrate, and the like. Alkyl and aryl peroxides and/or peroxidases may also be used. Mixtures of two or more such oxidizing agents may also be used if desired. In some cases, hydrogen peroxide, percarbonate, persulfate, and combinations thereof are used in the developer composition.

The oxidizing agent may comprise from about 0.1 wt% to about 40 wt%, from about 1 wt% to about 30 wt%, or from about 2 wt% to about 30 wt% of the developer composition. Another potential oxidizing agent for use herein is a peroxymonocarbonate ion source. Preferably, such source is formed in situ from a hydrogen peroxide source and a bicarbonate ion source. The system is particularly effective in combination with ammonia or a source of ammonium ions. Thus, any source of these peroxymonocarbonate ions may be used. Sources suitable for use herein include sodium, potassium, guanidine, arginine, lithium, calcium, magnesium, barium, ammonium salts, or mixtures thereof of carbonate, carbamate, and bicarbonate ions, such as sodium carbonate, sodium bicarbonate, potassium carbonate, potassium bicarbonate, guanidine carbonate, guanidine bicarbonate, lithium carbonate, calcium carbonate, magnesium carbonate, barium carbonate, ammonium bicarbonate, or mixtures thereof. Percarbonate may also be used to provide both a source of carbonate ions and as an oxidizing agent.

Table 3:

color developer formulation

The inventive and comparative formulations (according to tables 1 and 2) were mixed with a bleach composition (bleach powder) and a bleach developer (30 or 40V) according to the weights provided in table 3.

The hair lightening compositions of examples A-D were mixed with a 40V developer composition (comprising hydrogen peroxide) at a mixing ratio of 1:2 (hair lightening composition: developer composition) and used to treat hair. The hair is then subjected to a cysteine analysis, which is a measure showing the extent of hair damage.

The bleaching mixtures of examples a-D were applied to conventional bleaching samples (Regular Bleach Swatche) obtained from International Hair Import Products for more than 50 minutes, based on achieving equivalent brightness enhancement effects compared to controls. The samples were rinsed and shampooed once before blow-drying.

Cysteine analysis measurements were performed showing the extent of damage to hair. Extensive studies of the effect of cysteine content on alpha-helical denaturation in keratin have shown that, for example, the melting temperature (transition temperature) of keratin increases linearly with cysteine content. The increased stability of the matrix region, attributable to the relatively high degree of crosslinking of the high proportion of disulfide bonds in the matrix, means that the transition of the helix embedded in the matrix becomes difficult, thus leading to an increase in the melting temperature. In contrast, a decrease in melting point, in particular a decrease in melting enthalpy (enthalpy of fusion), is generally observed in chemically treated hair.

The modulus of elasticity (Young's modulus) and stress at break were also measured to characterize hair and the extent of damage to hair. The modulus of elasticity represents a measure of the spring-like structure (elasticity) of the hair. A higher modulus of elasticity indicates that the hair is more elastic (less brittle). The breaking stress represents the force/area required to break the hair fibers. Higher breaking stress indicates stronger and stiffer hair fibers.

Differential scanning calorimetry (DCS) is a tool that can also be used to study the structural characteristics of hair fibers. Keratin undergoes a detectable transition at different temperatures. These transition temperature variations can be used to estimate how a particular hair treatment may affect hair fibers. In the present application, the denaturation temperature (T _d ). Denaturation temperature (T) _d ) Has been used as an indication of the thermal stability of hair fibres, which is at least partially affected by the cross-link density of the matrix (intermediate wire binding protein (intermediate filament associated proteins), IFAP). Thermal stability (T) _d ) And their relationship in determining the thermal stability of hair fibers has been established in the literature.

Results: the system was evaluated using a Mini Tensile Test (MTT) to measure the impact of bleaching on tensile strength and elastic modulus. Amino Acid Analysis (AAA) was performed on bleached hair fibers to measure the formation of citric acid, which indicates the amount of cysteine bond cleavage. The characteristics of cosmetic hair are evaluated by a professional stylist in a comparative head test. Stability assessment was performed based on standard procedures. The results of the cysteine test, modulus of elasticity, stress at break and DSC for hair treated with the hair lightening composition of examples a-C demonstrate significant improvements over the results of the cysteine test, modulus of elasticity, stress at break and DSC for hair treated with the hair lightening composition of example D. The baicalin/citric acid/glycine combination provides beneficial benefits to fiber integrity during hair bleaching, resulting in improved tensile strength and elastic modulus, and reduced formation of citric acid, compared to the same bleach without the active. Furthermore, the samples of examples a-C were found to provide durable smoothness and manageability to hair after bleaching. Examples a-C were found to be stable in a chamber at 45℃ and found to have no caking when mixed or built into the bleach. Examples a-C were evaluated by MTT, AAA and hairlane tests. Examples a-C were found to have higher tensile strength, higher modulus of elasticity and lower cysteine content than example D. In the hairlane test, the formulations of examples a-C were found to provide smooth and manageable properties to the volunteers being evaluated.
