Description

Hair care composition containing polyalkylene glycol(n) alkyl organic acid

technical field

The present invention relates to hair care compositions comprising polyalkylene glycol (n) alkylamines and organic acids.

Background technique

Human hair can become soiled due to contact with the surrounding environment and due to the sebum production of the scalp. Dirty hair gives it a dirty or greasy feel and is not aesthetically pleasing. Dirty hair needs regular shampooing.

Shampoo cleanses the hair by removing excess dirt and sebum. But shampooing leaves hair in a damp, tangled, and generally unmanageable state. After shampooing, hair is often left in a dry, tangled, dull, or frizzy state due to the removal of the hair's natural oils and other natural conditioning and moisturizing ingredients. On drying, the hair's static level may further increase, which may interfere with combing and result in the hair being in a condition commonly referred to as "flyaway hair". Some consumers find such flyaway hair and the corresponding increase in overall hair volume to be undesirable. Accordingly, it would be desirable to provide smooth, soft, silky feel, and healthy looking hair while reducing flyaway hair volume and overall hair volume. Additionally, there is often a need to increase the biodegradability of hair care compositions.

Various methods have been developed to solve these problems. Such methods are generally achieved by incorporating hair conditioning compounds, typically cationic compounds such as cationic surfactants, into hair care compositions in an attempt to enhance smoothness, softness and shine. Such hair conditioning compounds also reduce static. It is theorized that these cationic compounds, including quaternary ammonium compounds, serve to neutralize the static charge on the hair and thereby reduce flyaway hair volume to some extent. However, these hair conditioning compounds do not sufficiently reduce overall hair volume and may roughen the hair, skin, or scalp.

Therefore, there is a need for hair care compositions that effectively deposit on the hair to significantly reduce total hair volume by reducing bulk hair volume and flyaway hair volume. There is also a need for hair care compositions that are stable when oily compositions are added. There is also a need for hair care compositions that provide improved mildness to the hair, skin and scalp and have improved biodegradability.

polyalkylene glycol(n) alkylamines,

Polyalkylene Glycol(n) Alkyl Ammonium Salt

The hair care compositions of the present invention contain polyalkylene glycol (n) alkyl amines or polyalkylene glycol (n) alkyl ammonium salts which are substantially liquid at room temperature and generally have a melting point of less than about 45 °C, more preferably less than about 30 °C.

Without being bound by theory, it is believed that in the presence of an organic acid having at least three acidic groups, the polyalkylene glycol(n) alkylamine or polyalkylene glycol(n) alkylammonium salt and the cationic surface Active agents and solid fatty compounds can provide an improved gel matrix, i.e. a high level of gel matrix, thereby providing significant consumer desired benefits such as improved hair look and feel, reduced bulk hair volume, reduced less flyaway hair volume and reduced total hair volume. Without being bound by theory, it is believed that the improved gel network is due to each acidic group in the organic acid and the polyalkylene glycol(n) alkylamine or polyalkylene glycol(n) alkyl ammonium A bond is formed between the salts.

Without wishing to be bound by theory, it is believed that the gel matrix significantly improves the deposition of polyalkylene glycol(n)alkylamines and polyalkyleneglycol(n)alkylammonium salts on the hair. In highly preferred embodiments, the gel base is a lamellar gel base, such gel bases providing improved deposition, wet hair feel, softness, and other substantial benefits. In the presence of certain components, the gel matrix can become unstable or at worst destroyed. Such components include high levels of anionic surfactants and film-forming polymers with anionic moieties. Highly preferred compositions are substantially free of such components.

Without being bound by theory, it is believed that the polyalkylene glycol (n) alkylamines and polyalkylene glycol (n) alkyl ammonium salts used in the present invention provide the benefit of reducing bulk hair volume through the following mechanism: The amino and hydrophobic alkyl moieties help anchor the compound to the hair fiber, even under rinsing conditions, while the hydrophilic alkoxy groups attract water molecules and act as moisture buffers that slow down changes in the water content of the hair fiber. buffer). This helps keep the hair fiber bouncy, supple and plastic. This in turn keeps the hair fibers in a well-aligned configuration (relative to other hair fibers) and recovers easily from the deformed state. This further increases the likelihood that the hair fibers will remain parallel and/or hang straight down. This significantly reduces the space between individual hair fibers, thus reducing bulk hair volume and flyaway hair volume.

Without being bound by theory, it is believed that polyalkylene glycol(n) alkylamines and polyalkylene glycol(n) alkyl ammonium salts also reduce flyaway hair volume. It is believed that the amine moiety in the polyalkylene glycol (n) alkylamine is positively charged by the organic acid of the present invention, or the amine moiety of the polyalkylene glycol (n) alkyl ammonium salt is positively charged Yes, the amine moieties are attracted and deposited well on the hair surface. Therefore, in addition to the effect of moisturizing hair fibers, polyalkylene glycol (n) alkylamines and polyalkylene glycol (n) alkyl ammonium salts can also reduce the static charge and flexibility of hair fibers ( crookedness). This reduces electrostatic repulsion and spaces between hair fibers, resulting in a reduction in flyaway hair volume.

Those skilled in the art can understand that the compounds disclosed in this section of the specification can belong to more than one category in some cases, for example, certain fatty alcohol derivatives can also be classified as fatty acid derivatives. However, a given class is not intended to limit that particular compound, but rather for ease of classification and nomenclature. Furthermore, those skilled in the art will appreciate that some compounds with certain desired carbon atoms may have melting points below 25°C, depending on the number and location of double bonds, and the length and location of branches. Such low melting point compounds are not included in this section. Non-limiting examples of high melting point compounds can be found in International Cosmetic Ingredient Dictionary, Fifth Edition, 1993, and CTFA Cosmetic Ingredient Handbook, Second Edition, 1992.

Solid fatty compounds are present in the compositions of the present invention at a level of from about 0.1% to about 20% by weight, preferably from about 1% to about 15% by weight, preferably from about 2% to about 10% by weight. In the composition of the present invention, the content of solid fatty compound depends on the weight ratio of solid fatty compound to cationic surfactant, said weight ratio is preferably from about 0.5:1 to about 30:1, more preferably about 1:1 1 to about 20:1, more preferably about 2:1 to about 10:1.

Solid fatty compounds of high purity single compound are preferred. A single compound of pure fatty alcohols selected from pure cetyl alcohol, stearyl alcohol and behenyl alcohol is highly preferred.

"Pure" herein means that the compound is at least about 90% pure, preferably at least about 95% pure. These single compounds of high purity provide good wash-off properties from the hair when the consumer washes off the compositions of the present invention.

Commercially available solid fatty compounds that can be used in the present invention include: cetyl alcohol, stearyl alcohol and NAA series available from Shin-nihon Rika (Osaka, Japan) under the trade name KONOL series and NOF (Tokyo, Japan) under the trade name NAA series.

water

The compositions of the present invention comprise water. Deionized water is preferably used. Water from natural sources including inorganic cations may also be used, depending on the desired properties of the product. The compositions of the present invention generally comprise at least about 60%, preferably at least about 70%, more preferably at least about 75% to 95% water. Deionized water is preferably used. Water from natural sources including inorganic cations may also be used, depending on the desired properties of the product.

The pH of the compositions of the present invention is preferably about 2-9, more preferably about 2.5-6, still more preferably about 3-4.5. Buffers and pH adjusting agents may be included to achieve the desired pH.

polypropylene glycol

The hair care compositions of the present invention preferably contain polypropylene glycol having a weight average molecular weight of from about 200 g/mol to about 100,000 g/mol, preferably from about 1,000 g/mol to about 60,000 g/mol. Without wishing to be bound by theory, it is believed that the polyethylene glycols herein deposit on or absorb into the hair to act as moisturizer buffers, and/or provide one or more other desirable hair conditioning benefits. The term "polypropylene glycol" as used herein includes single-polypropylene glycol-chain segment polymers and multi-polypropylene glycol-chain segment polymers. Branched polymers of the present invention such as multi-polypropylene glycol-chain segment polymers are described, for example, in "Principles of Polymerization", pp. 17-19, G Odian, (John Wiley & Sons, Inc., 3rd Edition, 1991) middle.

The polypropylene glycols of the present invention are generally polydisperse polymers. The polypropylene glycols useful herein have a polydispersity of from about 1 to about 2.5, preferably from about 1 to about 2, more preferably from about 1 to about 1.5. As used herein, the term "polydispersity" refers to the degree of molecular weight distribution of a polymer sample. Specifically, polydispersity is a ratio greater than 1 equal to weight average molecular weight divided by number average molecular weight. For further discussion of polydispersity see "Principles of Polymerization", pp. 20-24, G Odian, (John Wiley & Sons, Inc., 3 ^rd ed., 1991).

Depending on the degree of polymerization and whether other groups are attached, the polypropylene glycols useful in the present invention can be water soluble, water insoluble, or have limited solubility in water. The desired solubility of polypropylene glycol in water depends largely on the type of hair care composition (eg leave-on or rinse-off). The solubility of the polypropylene glycol used in the present invention in water can be selected by those skilled in the art based on various factors. Accordingly, for leave-on hair care compositions it is preferred that the polypropylene glycol is a water-soluble polypropylene glycol. Solubility information is readily available from suppliers of polypropylene glycols such as Sanyo Kasei (Osaka, Japan). However, the present invention may also be in the form of a rinse-off hair care composition. While not wishing to be bound by theory, it is believed that in such compositions the water soluble polypropylene glycol may be very easily washed off before it is effectively deposited on the hair and provides the desired benefit. Therefore for such compositions polypropylene glycols with low water solubility, or even water insolubility, are preferred. Therefore, for rinse-off hair care compositions, the solubility of polypropylene glycol in water at 25°C is preferably less than about 1 g/100 g water, more preferably less than about 0.5 g/100 g water, even more preferably less than about 0.1 g/100g water.

Polypropylene glycol is generally present at levels of from about 0.5% to about 10%, preferably from about 2% to about 6%, by weight of the hair care compositions.

Preferably, the polypropylene glycol is selected from mono-polypropylene glycol-chain segment polymers, multi-polypropylene glycol-chain segment polymers, and mixtures thereof; more preferably, selected from mono-polypropylene glycols of formula I below -chain segment polymers, many-polypropylene glycol-chain segment polymers of general formula II, and mixtures thereof

polysiloxane compound

Silicone compounds useful herein include volatile soluble or insoluble, or nonvolatile soluble or insoluble silicone conditioning agents. Soluble means that the silicone compound is miscible with the carrier of the composition to form part of the same phase. Insoluble means that the polysiloxane forms a separate, discontinuous phase from the carrier, for example in the form of an emulsion or suspension of polysiloxane droplets. The polysiloxane compounds of the present invention may be prepared by any suitable method known in the art, including emulsion polymerization. The silicone compound may be incorporated into the compositions of the present invention in the form of an emulsion, with or without the aid of anionic surfactants, nonionic surfactants, cationic surfactants and their Mixtures of surfactants are formed by mechanical mixing, or by emulsion polymerization at the synthesis stage.

References disclosing suitable non-volatile dispersed silicone compounds include U.S. Patent 2,826,551 to Geen; U.S. Patent 3,964,500 to Drakoff, published June 22, 1976; Pader's, published December 21, 1982; U.S. Patent 4,364,837; and Woolston's British Patent 849,433. "Silicon Compounds", issued by Petrarch Systems, Inc., 1984, provides an extensive, but not exclusive, list of suitable polysiloxane compounds.

Another non-volatile dispersed silicone that is especially suitable is silicone gum. The term "silicone gum" refers to a polyorganosiloxane having a viscosity at 25°C of greater than or equal to 1,000,000 centistokes. It should be recognized that the silicone gums described herein may also have some overlap with the silicone compounds disclosed above. This overlap is not a limitation to any of these substances. Silicone gums are described by Petrarch and others, including U.S. Patent 4,152,416 to Spitzer et al., published May 1, 1979, and Noll, Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968. General Electric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76 also describe silicone gums. "Silicone gums" generally have a weight average molecular weight in excess of about 200,000, usually from about 200,000 to about 1,000,000. Specific examples include polydimethylsiloxane, poly(dimethylsiloxane methylvinylsiloxane) copolymer, poly(dimethylsiloxane diphenylsiloxane methylvinylsiloxane) alkane) copolymers and their mixtures.

It is also possible to use silicone resins which are highly crosslinked silicone systems. The crosslinking is introduced by incorporation of trifunctional and tetrafunctional silanes together with monofunctional or difunctional silanes or both during the production of the polysiloxane resin. As is well known in the art, the degree of crosslinking required to produce a silicone resin will vary depending on the particular siloxane units incorporated into the silicone resin. In general, polysiloxane materials having sufficient levels of trifunctional and tetrafunctional siloxane monomer units, and therefore crosslinking, such that they form hard or strong films when dry, can Considered a polysiloxane resin. The ratio of oxygen atoms to silicon atoms in a particular polysiloxane material is an indicator of the level of crosslinking. Silicone materials having an oxygen atom to silicon atom ratio of at least about 1.1 are typically the silicone resins described herein. Preferably, the ratio of oxygen atoms to silicon atoms is at least about 1.2:1.0. Silanes that can be used to prepare polysiloxane resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl-, and methylvinyl methyl substituted silanes, and tetrachlorosilanes, of which methyl substituted silanes are the most commonly used. Preferred resins are available from General Electric as GESS4230 and SS4267. Commercially available silicone resins are generally supplied in dissolved form in low viscosity volatile or nonvolatile silicone fluids. It will be apparent to those skilled in the art that the silicone resins useful in the present invention should be provided in such dissolved form and incorporated into the compositions of the present invention. Without being bound by theory, it is believed that the silicone resins enhance the deposition of other silicone compounds on the hair and enhance the shine of hair having high refractive index volume.

Other silicone resins that can be used are silicone resin powders such as the material with the CTFA name polymethylsilsequioxane available from Toshiba Silicones as Tospearl™.

Methods for preparing these polysiloxane compounds can be found in Encyclopedia of Polymer Science and Engineering, Volume 15, Second Edition, pp. 204-308, John Wiley & Sons, Inc., 1989.

Silicone materials and silicone resins are particularly conveniently denoted by an abbreviated nomenclature system known to those skilled in the art as the "MDTQ" nomenclature. Under this nomenclature, polysiloxanes are described in terms of the presence of the various siloxane monomer units that make up the polysiloxane. Briefly, the symbol M refers to the monofunctional unit (CH ₃ ) ₃ SiO _0.5 ; D refers to the difunctional unit (CH ₃ ) ₂ SiO; T refers to the trifunctional unit (CH ₃ ) SiO _1.5 ; and Q refers to the tetrafunctional unit. Functional unit SiO2. Those unit symbols such as M', D', T' and Q' appended with "prime" refer to substituents other than methyl and must be specifically defined at each occurrence. Typical alternative substituents include groups such as vinyl, phenyl, amino, hydroxy, and the like. Under the MDTQ system, polysiloxanes are completed in terms of symbolic subscripts denoting the total number of the various units in the polysiloxane, or in terms of their average value, or as specifically indicated ratios combined with molar ratios of the different units of weight-average molecular weight. A description of the alkane material. A higher relative molar amount of T, Q, T' and/or Q' relative to D, D', M and/or M' in a polysiloxane resin means a higher level of crosslinking. However, as noted above, the overall level of crosslinking can also be expressed by the ratio of oxygen to silicon.

Preferred polysiloxane resins useful herein are MQ, MT, MTQ, MQ and MDTQ resins. Accordingly, the preferred polysiloxane substituent is methyl. Especially preferred are MQ resins wherein the M:Q ratio is from about 0.5:1.0 to about 1.5:1.0 and the resin has a weight average molecular weight from about 1000 to about 10,000.

Examples of other preferred additional ingredients that may be formulated into the compositions of the present invention include: other conditioning agents such as hydrolyzed collagen available from Hormel under the tradename Peptein 2000, panthenol available from Roche, panthenol ethyl ether available from Roche , hydrolyzed keratin, protein, herbal extracts such as Polygonatum multiflori extract and nutrients; vitamins and/or amino acids such as vitamin E available from Eisai under the trade name Emix-d, tyrosine methyl ether, group Amino acid and lysine hydrochloride; Surfactants such as cationic surfactants, nonionic surfactants, amphoteric surfactants and mixtures thereof; Preservatives such as benzyl alcohol, methyl p-hydroxybenzoate, p-hydroxy Propyl benzoate and imidazolidinyl urea; pH adjusters such as citric acid, sodium citrate, succinic acid, phosphoric acid, sodium hydroxide, sodium carbonate; salts such as potassium acetate and sodium chloride; colorants such as FD&C or D&C dyes hair oxidizing (bleaching) agents such as hydrogen peroxide, perborates, and persulfates; hair reducing agents such as thioglycolates; fragrances; chelating agents such as disodium edetate; Masking and absorbing agents such as optical brighteners and octyl salicylate; and anti-dandruff agents such as zinc pyrithione, piroctone olamine, 3,4,4'-trichloro Carboanilide (trichlosan), triclocarban, and salicylic acid.

Preparation

The hair care compositions of the present invention are conveniently and inexpensively prepared by any method known in the art. To form the highly preferred gel matrix, the water is generally heated to at least about 70°C, preferably to about 80°C to about 90°C. The cationic surfactant and solid fatty compound are combined with water to form a mixture. In order to provide the composition with improved stability, it is preferred to add polyalkylene glycol (n) alkylamines and/or polyalkylene glycol (n) alkyl ammonium salts in this step. The temperature of the mixture is preferably maintained above the melting temperature of the cationic surfactant and the melting temperature of the solid fatty compound and the entire mixture is homogenized. After mixing until no solids are observed, the mixture is gradually cooled (eg, at a rate of about 2°C/minute) to a temperature below 60°C, preferably below 55°C. During this gradual cooling, a significant increase in viscosity was observed from about 55°C to about 75°C. This indicates the formation of a highly preferred gel matrix. Any other additional components may also be added at this stage and allowed to cool to room temperature.

The hair care composition prepared by the above method has good stability and excellent performance.

Instructions

The hair care compositions of the present invention preferably have a viscosity of about 5,000-40,000 cps as measured by a Brookfield Viscometer at 25°C at a shear rate of 1.0 rpm.

The hair care compositions according to the invention are suitable for use as, for example, hair cosmetic compositions, hair styling compositions, leave-on and/or rinse-off hair conditioning compositions, especially suitable for use as rinse-off hair conditioning compositions. These hair care compositions are used in conventional manner to provide conditioning, cleansing, styling and/or other benefits of the present invention. Such use depends on the type of composition used, but generally involves applying an effective amount of the product to the hair, after which the hair care composition can be washed from the hair (for a conditioner) or left on ( for gels, lotions and creams). By "effective amount" is meant an amount sufficient to provide the desired bulk reducing hair benefit. Typically from about 1 g to about 50 g is applied to the hair and/or scalp. The composition can be distributed throughout the hair, typically by rubbing or rubbing the hair and scalp, or the composition can be selectively applied to certain sections of the hair. Preferably, the compositions are applied to wet or damp hair and rinsed with plenty of water before drying the hair. After applying such hair care compositions to the hair, the hair is dried and styled according to the preference of the user. Alternatively, as in the case of hair styling compositions, they can be applied to dry hair, which is then combed or styled according to the user's preference.

Image Analysis Solution

The Image Analysis Protocol is a system and method designed to digitally determine and analyze the components of bulk hair area and flyaway hair area that form the total hair area. This protocol provides a quantifiable, repeatable method of accurately identifying, measuring, and comparing total hair area, flyaway hair area, and bulk hair area before and after treatment with a hair care composition. The total hair area, flyaway hair area, and bulk hair area are directly related to the total hair volume, flyaway hair volume, and bulk hair volume, respectively. The hair care compositions of the present invention provide a significant, noticeable reduction in bulk hair area, preferably at least about 10%, as measured by the method described hereinafter. The hair care compositions of the present invention provide a significant, noticeable reduction in the area of the three types of hair as determined by the method described below, i.e. a reduction of at least about 10%, more preferably a reduction of at least about 15%, and More preferably, the reduction is about 20%, the flyaway hair area is reduced by at least about 20%, more preferably by at least about 30%, and the total hair area is reduced by at least about 12.5%, more preferably by at least about 20%, and still more A reduction of at least about 75% is preferred.

It has been found that a reduction in bulk hair area is associated with one or more significant consumer desired benefits such as improved manageability and/or improved combability. For example, it is believed that reduced bulk hair area is associated with wet hair, which is softer, more malleable, smoother and more supple than dry hair. When the hair is wet, the bulk hair area is reduced because the hairs are better aligned with each other and there is less space between individual hairs. Moisturized hair is also easier to comb and control.

Referring to the accompanying drawings, accompanying drawing 1 is a top view of a preferred embodiment of the image analysis system used by the present invention. The image analysis system 10 is composed of a white screen 12 , an illumination device 14 , a sample holder 16 , a high-resolution digital camera 18 and a personal computer 20 . A sample holder 16 is placed between a white screen 12 and a high resolution digital camera 18 . The sample holder 16 is typically a clip or clamp capable of stably suspending a hair sample 22 about 40 cm in front of the white screen 12 . The sample holder 16 is typically about 80 cm from the high resolution digital camera 18 and is positioned above the field of view of the high resolution digital camera so as not to be visible in the captured image.

The white screen 12 is a matte (eg, non-glare) white screen that, when illuminated, provides a constant and repeatable background of the hair sample 22 being measured. Since the difference between bulk hair area and flyaway hair area is judged based on the brightness of the image (see below), it is important to photograph the hair sample in front of a background with constant brightness. As shown in Figure 1, the preferred lighting setup 14 consists of a pair of photographic lights positioned on each side of the sample and directed toward a white screen. Each photographic light is preferably a pair of fluorescent tube lights housed within a lighting fixture, and is generally about 20 cm to about 60 cm from the side of the sample holder 16. This places it far enough away from the hair sample 22 that it will not be captured by the high resolution digital camera 18 . This ensures that the captured image only includes the image of the hair sample 22 and does not include, for example, the back side of the lighting device 14 . Therefore, the lighting device 14 should not interfere with or block the photograph being taken. Also, in such a configuration, the hair sample 22 is not directly illuminated by the lighting device 14 . Instead, the light first reflects off the white screen 12 and then passes through the hair sample 22 to reach the high resolution digital camera 18 . The high resolution camera 18 focuses on the hair sample 22 instead of the white screen 12 . For ease of use, a high resolution digital camera 18 is connected to a personal computer 20 and automatically transfers the captured images to the computer's imaging software. Such an arrangement provides an accurate picture of the outline of the hair sample 22 and avoids any glare and/or shadows that might interfere with the measurement and analysis of the hair sample 22 .

Preferably, the image analysis system should be located away from drafts or other factors that may disturb the hair sample, and in a controlled temperature and humidity environment to ensure reproducible results. A high-resolution digital camera (eg, Model HC-25003-CCD available from Fujifilm Co. of Tokyo, Japan) has a resolution of at least 1280 horizontal pixels and 1000 vertical pixels. The high resolution digital camera was calibrated to a linear gain such that the incremental differences between all luminance values (8-bit, 0-255 luminance value scale) were equal. Such calibration can be accomplished, for example, by using a standard grayscale calibration bath and/or an internal look-up table (LUT) of a high-resolution digital camera. For calibration, a white screen (when illuminated with a lighting device) should have a luminance value greater than about 245, preferably about 250 to about 255.

A typical hair sample consists of 15cm (5g) Asian black straight hair switches (hair switches) (purchased from Kawamuraya Co. of Osaka, Japan) or Caucasian brown straight hair switches (purchased from International Hair Importers & products Inc. of Bellerose, New York, USA). Straight black hair tufts for Asians are preferred because their contrast against a white screen is easier to see. Measurements using this image analysis scheme are significantly easier and more reproducible to perform when using black hair switches. However, the hair area reduction benefits, and corresponding hair volume reduction benefits of the present invention apply to all hair types. Furthermore, it has been shown that the results obtained with hair switches do not differ much from those obtained during actual use on humans.

Hair samples were prepared as follows:

1) Wet the hair swatch with warm water (38°C) for 30 seconds.

2) Apply 1 ml of the ammonium lauryl sulfate solution on the hair swatch and lather for 30 seconds.

3) Rinse the hair swatch for 60 seconds.

4) Soak the hair sample in warm water for 24 hours.

5) Apply 1 ml of the ammonium lauryl sulfate solution on the hair swatch and lather for 30 seconds.

6) Rinse the hair swatch for 30 seconds.

7) Apply 1 ml of the ammonium lauryl sulfate solution to the hair swatch and lather for 30 seconds.

8) Rinse the hair swatch for 60 seconds.

9) For treated hair swatches: Apply 1 ml of the hair care composition to be tested to the hair swatch.

10) For treated hair swatches: Rinse the hair swatches for 10 seconds.

11) Comb the hair swatch 5 times starting from the front.

12) Comb the hair swatch 5 times starting from the back.

13) Squeeze out excess water from the hair sample and round the cross-section.

14) Place the hair swatches in a 21°C/65% relative humidity room and dry for 24 hours.

15) The hair sample is then ready to be measured by the image analysis system.

Only the treated hair samples were subjected to steps 9 and 10. To compare the effect of hair care compositions on bulk hair area, flyaway hair area, and total hair area, "untreated photos" and then "treated photos" of hair samples were taken first. Compare the treated and untreated bulk hair area, flyaway hair area, and total hair area shown in the photos. According to the method described above, the same hair switch is generally first used on a sample of untreated hair and then on a sample of treated hair. Use the same hair clusters to minimize variance between samples.

Once a hair sample (treated or untreated) 22 has been prepared, it is placed on the sample holder 16 positioned in front of the white screen 12 . The distances from the high-resolution digital camera 18 and the hair sample 22 should be the same for the unprocessed and processed photographs. For unprocessed and processed photographs, the hair samples should be lined up so that the high resolution digital camera can capture the broadest outline (in terms of the bottom end of the hair sample). Such an arrangement approximates the way hair is arranged on the scalp and therefore provides the most accurate view of the effect on hair area (and therefore hair volume) after treatment. This also ensures that the effect of reduction in bulk hair area, reduction in flyaway hair area and/or reduction in total hair area can be accurately measured.

Once the hair is substantially stationary, 8-bit, gray-scale) photographs are taken with a high-resolution digital camera 18 . Typically, a high resolution digital camera 18 assigns each pixel a brightness value of 0 (pure black) - 255 (pure white). The photos are then transferred to the personal computer 20 . Alternatively, but not preferably, a personal computer can assign an intensity value of 0-255 to each pixel. Such photographs are also referred to as "captured images" and may be stored electronically, eg, as TIFF (Tagged Image File Format) files for future reference. In captured images, each hair sample appeared to appear gray to black against a white background. Imaging software (eg, Optimas v.6.2, available from Media Cybernetics of Silver Springs, Maryland, USA) then analyzes the captured images pixel by pixel. Imaging software uses the brightness value assigned to each pixel by the camera to classify each pixel as black (brightness value=0-120), gray (brightness value=121-235), or white (brightness value=236 -255). The imaging software then defines "piles of hair" in the captured image as the largest contiguous area bounded by black lines. "Flying hair" is defined as the black, gray and white areas bounded by one or more gray lines excluding piles of hair. The term "bounded" as used herein in relation to imaging software means that the referenced area is completely surrounded by at least one specified shading.

The imaging software then calculates the area of each region, usually expressed in ^cm2 , to obtain the bulk hair area and flyaway hair area. The total hair area is the sum of the bulk hair area and the flyaway hair area. Thus, bulk hair area and/or flyaway hair area can also be calculated as a percentage of the total hair area. In a preferred embodiment, the imaging software automatically sets the total area of untreated hair to 1.0 and normalizes other values accordingly. The imaging software also maps and/or color codes areas of hair accumulation and/or areas of hair scattering for easy reference.

The reduction in hair volume after treatment is based on data obtained by comparative analysis of treated and untreated hair samples. Calculate the total untreated hair area (UTA), untreated bulk hair area (UBA) and untreated flyaway hair area (UFA). This was then compared to the calculated Total Treated Hair Area (TTA), Treated Bulk Hair Area (TBA) and Treated Hair Area (TFA). The reduction in bulk hair area after treatment is equivalent to the reduction in bulk hair volume and is calculated according to the following formula:

Reduction in bulk hair area = 100*[1-(TBA/UBA)].

Similarly, the percent reduction in flyaway hair area after treatment is equivalent to the reduction in flyaway hair volume and is calculated according to the following formula:

Reduction in flyaway hair area = 100*[1-(TFA/UFA)].

The percentage reduction in total hair area after treatment is equivalent to the reduction in total hair volume and is calculated according to the following formula:

Reduction in total hair area = 100*[1-(TTA/UTA)].

A given hair care composition (or control) is generally tested on at least 3 separate hair samples. The reduction in bulk hair area, the reduction in flyaway hair area, and the reduction in total hair area are then calculated for each hair sample, and the average reduction in bulk hair area, the average reduction in flyaway hair area, and the average total hair area are calculated. decrease.

In a preferred embodiment of the image analysis protocol, 2 pictures are taken for each treated and untreated sample. The first picture corresponds to the widest profile of the hair sample, while the second picture corresponds to the narrowest profile of the hair sample, typically a 90° rotation from the widest profile. The average of untreated bulk hair area, treated bulk hair area, etc. is then calculated. These averages are then used in the above formula. Such a method may be especially useful for lightly curly hair samples, either due to their natural contour or due to washing.
