Description

[Technical Field]

[0001] The present invention relates to a hair care composition for reducing oil transfer from the scalp to the hair. [Background technology]

[0002] Scalp oiliness affects many aspects of scalp and hair physiology, as well as satisfaction with hair appearance and feel.The perception of undesirable hair oiliness is influenced by several internal factors, such as scalp type, hair type, hormones, age, diet, and external factors, such as hair care products, climate, and lifestyle.Although today's shampoo products are designed to remove oil, people are often dissatisfied with the length of time their hair feels clean.Shampoos typically do not affect the transfer of scalp oil from the scalp to hair, which occurs throughout the day and night.It has not been found that specific materials and formulations can modify the polarity of the hair surface to help reduce the transfer of oil from the scalp to hair. Summary of the Invention [Means for solving the problem]

[0003] The present application is directed to a hair care product composition comprising a material or mixture of materials that polarizes hair, wherein one or more materials are selected from a synthetic or naturally occurring hydrophilic polymer and / or a cationic surfactant. The present invention is directed to a hair care composition comprising about 0.05% to 5% of a hydrophilic polymer selected from the group consisting of polyvinyl alcohol and derivatives, polyacrylate ethers, polyvinylpyrrolidone, polyvinylpyrrolidone copolymers (vinylpyrrolidone / dimethylaminoethyl methacrylate), vinyl cyanide, vinyl phosphate, vinyl phosphonate, vinyl sulfate, vinyl sulfonate, polyethyleneimine and other polyamines, cellulose, collagen, polyethylene glycol, and maleic acid / olefin polycarboxylate copolymers, and mixtures thereof, wherein the hair care composition provides a water contact angle on the hair of less than 85°C. The present invention is directed to hair care compositions that have reduced total lipid levels on hair compared to a control, where the total lipid level on hair is less than 0.15 as measured as total lipids (CH2) using Fourier-Transform Infra-red spectroscopy (FTIR). DETAILED DESCRIPTION OF THE INVENTION

[0004] Unless otherwise specified, all percentages and ratios used herein are by weight of the total composition. Unless otherwise specified, it is understood that all measurements are made at ambient conditions, where "ambient conditions" means conditions at about 25°C, less than about 1 atmosphere, and about 50% relative humidity (RH). All numerical ranges are inclusive of narrower ranges, and the stated upper and lower range limits are combinable to create additional ranges not expressly stated.

[0005] The compositions herein can comprise, consist essentially of, or consist of the essential components as well as optional components described herein. As used herein, "consisting essentially of" means that the composition or component may include additional components, but only if the additional components do not materially alter the basic and novel characteristics of the claimed composition or method.

[0006] "Applying" or "application" as used in reference to a composition means applying or spreading a composition of the present invention onto keratinous tissue, such as hair.

[0007] "Dermatologically acceptable" means that the composition or components described are suitable for use in contact with human skin tissue without undue toxicity, incompatibility, instability, allergic response, etc.

[0008] By "safe and effective amount" is meant an amount of a compound or composition sufficient to significantly induce a beneficial effect.

[0009] "Rinse-off" in reference to a composition means a composition that is intended to be applied to the keratinous substrate and subsequently washed, rinsed, or wiped off within minutes of application. These "rinse-off" compositions should be distinguished from "leave-on" compositions that are applied and intended to be left on the keratinous tissue for a longer period of time.

[0010] "Leave-on" in reference to a composition refers to a composition intended to be applied and left on the keratinous tissue. These leave-on compositions should be distinguished from compositions that are applied to hair and subsequently removed (within minutes) by either washing, rinsing, or wiping. Leave-on compositions exclude rinse-off applications such as shampoos, rinse-off conditioners, facial cleansers, hand detergents, body washes, or personal cleansers. Leave-on compositions may be substantially free of cleansing or detersive surfactants. For example, a "leave-on composition" may be left on the keratinous tissue for at least 5 minutes. For example, a leave-on composition may contain less than 1% detersive surfactant, less than 0.5% detersive surfactant, or 0% detersive surfactant. However, the composition may contain emulsifiers, dispersants, or other processing surfactants that are not intended to provide any significant cleansing benefit when topically applied to hair.

[0011] By "soluble" is meant that at least about 0.1 g of solute will dissolve in 100 mL of solvent at 25° C. and 1 atm pressure.

[0012] Unless otherwise specified, all percentages are by weight of the total composition. All ratios are by weight unless specifically stated otherwise. All ranges are inclusive and combinable. Significant figures do not represent a limitation on the indicated amount or on the precision of the measurements. The terms "molecular weight" or "M.Wt.", as used herein, refer to weight average molecular weight unless otherwise specified. Weight average molecular weight can be measured by gel permeation chromatography. "QS" means quantity sufficient to make 100%.

[0013] As used herein, the terms "substantially free of" or "substantially free from" mean less than about 1%, or less than about 0.8%, or less than about 0.5%, or less than about 0.3%, or about 0%, by weight of the total composition.

[0014] As used herein, "hair" means mammalian hair, particularly hair on the human head and scalp, including scalp hair, facial hair, and body hair.

[0015] "Cosmetically acceptable," as used herein, means that the composition, formulation, or components described are suitable for use in contact with human keratinous tissue without undue toxicity, incompatibility, instability, allergic reaction, etc. All compositions described herein intended for direct application to keratinous tissue are limited to being cosmetically acceptable.

[0016] As used herein, "derivatives" include, but are not limited to, amide, ether, ester, amino, carboxyl, acetyl, acid, salt, and / or alcohol derivatives of a given compound.

[0017] As used herein, "polymer" refers to a chemical substance formed from the polymerization of two or more monomers. As used herein, the term "polymer" includes all materials made by the polymerization of monomers, as well as natural polymers. A polymer made from only one type of monomer is called a homopolymer. A polymer made from two or more types of different monomers is called a copolymer. The distribution of different monomers can be calculated statistically or block by block, and both possibilities are suitable for the present invention. Unless otherwise specified, the term "polymer" as used herein includes all types of polymers, including homopolymers and copolymers.

[0018] The mechanism of action for reducing oil transfer from the scalp to hair involves surface modification of the hair surface to create a polar surface (hydrophilicity, high surface energy, lower water contact angle on the hair). Because hair growing from the scalp is inherently hydrophobic, after showering with a typical cleansing shampoo or hair product, the deposition of conditioning ingredients such as silicones and fatty alcohols will maintain the same level of hydrophobicity or increase the hydrophobicity. Day and night, oil is constantly transferred from the scalp to the hair before the next wash, and the more hydrophobic the hair, the more oil will transfer from the scalp to the hair and the faster it will transfer. Current technology focuses on removing oil and reducing oil secretion from the sebaceous glands, which cannot stop hair from becoming greasy day and night as oil continues to transfer from the scalp to the hair. Therefore, it is desirable to incorporate hydrophilic polymers and / or cationic surfactants into hair compositions to modify the polarity of the hair surface and help reduce oil transfer from the scalp to the hair. The reduction of oil transfer improves hair feel by reducing or eliminating greasy or oily feeling.This treatment method makes hair cleaner for a longer period of time, which is achieved by polarizing the hair surface and reducing oil transfer from the scalp to the hair.The degree of hydrophilicity on hair can be determined by measuring water contact angle measurements using a mobile surface analyzer (MSA), a technique known in the art.The amount of oil reduction on hair can be measured as total lipids (CH2), triglycerides, fatty acids using Fourier transform infrared spectroscopy (FTIR), or by using a sebumeter, a technique known in the art.

Hydrophilic polymers The hydrophilic polymer can be synthetic or naturally occurring and can be a single polymer, a mixture of two or more polymers, or a copolymer with different polymeric units. Hydrophilic polymers include, but are not limited to, polyacrylates (and esters), other functionalized polyolefins (such as PVA (polyvinyl alcohol and esters)), PVA ethers, PVP (vinylpyrrolidone), PVP copolymers (vinylpyrrolidone / dimethylaminoethyl methacrylate), vinyl cyanides, vinyl phosphates, vinyl phosphonates, vinyl sulfates, vinyl sulfonates, polyethyleneimine and other polyamines, polyethylene glycol, and maleic acid / olefin polycarboxylate copolymers. The olefin segment can include various linear, branched, and cyclic alkenes. Suitable alkenes can include or be derived from propylene, ethylene, or butylene. Particularly suitable alkenes can include or be derived from butylenes, such as isobutylene and diisobutylene. The hydrophilic polymer can have a cationic charge. In the present invention, the hydrophilic polymer may be a polyquaternium-10, such as UCARE Extreme Polymer supplied by Dow Inc., or a cetyl hydroxyethyl cellulose, such as Polysurf 67 CS or Natrosol 330 PLUS CS, both supplied by Ashland.Other suitable polymeric agents include silicone materials such as polydimethylsiloxane materials (e.g., Wacker HC303 from Wacker Silicones), fluorinated acrylic copolymers (e.g., Capstone ST100 and ST300 from Dupont), polycarboxylate copolymers (e.g., Acusol 460 from Dow), and acrylic polymers (Polyquart® Pro A from BASF, Rhoplex EZ Clean 200 from Dow, Polyquart® Pro, Polyquart® Ampho 149, and Polyquart® EcoClean from Cognis), as well as other polyethers, poly(styrene maleic anhydride), polyesters, polyureas, polyurethanes, polycarbonates, polyacrylamides, sugars, and polymer analogs, chitosan, collagen, tapioca starch, and derivatives thereof.

[0032] Formulations and Examples The following are non-limiting examples of the present invention, which are provided for illustrative purposes only and should not be construed as limiting the present invention, as those skilled in the art will recognize that many variations thereof are possible without departing from the spirit and scope of the present invention.

[0033] Formulation Preparation and Treatment Protocol to Evaluate the Efficacy of Hydrophilic Polymers and Cationic Surfactants Preparation of leave-on treatment composition: The leave-on treatment composition is prepared by adding the hydrophilic polymer and, if desired, fragrance to an ethanol / water carrier and stirring until completely dissolved. The pH of the solution is adjusted using sodium hydroxide (50% w / w) or citric acid to a final pH of 4.0-6.0. Sepimax Zen is then added, if desired, and the solution is mixed using a high-speed mixer at 1800-2300 rpm for 2-5 minutes until a uniform composition is obtained.

[0034] Leave-on Hair Treatment Protocol: A 0.20 g amount of each composition of Examples I-IV is spread with a syringe onto a separate natural virgin brown hair switch weighing 2.0 g (a dose of 0.10 g of solution per gram of hair). The hair is allowed to air dry, and then the oil is transferred from the scalp mimic using the oil transfer method described above. The oil on the hair surface is then measured using FTIR or Sebumeter.

[0035] Preparation of shampoo composition: The shampoo composition provides the consumer with a desired hair cleansing experience in addition to preventing oil migration from the scalp to the hair.

[0036] The shampoo composition comprises from about 0.01% to about 5%, alternatively from about 0.05% to about 3%, alternatively from about 0.1% to about 2%, by weight of the shampoo composition, of a compound selected from the group consisting of hydrophilic polymers and mixtures thereof. The method includes applying a shampoo composition described herein to hair, followed by rinsing the shampoo composition from the hair.

[0037] Shampoo Hair Treatment Protocol: All tests are performed on Caucasian virgin hair weighing approximately 2.0 grams and approximately 6 inches in length. Hair Switches are commercially available from IHIP (International Hair Importers). Three Hair Switches 1 are used per rinse-off composition per dose. Each Hair Switch is washed with a clarifying shampoo and then treated with a rinse-off conditioner according to the following protocol: A 0.20 g amount of shampoo is spread onto a separate Hair Switch with a syringe; thus, the shampoo dose is 0.10 g per 1 g of hair. Each application consists of applying shampoo to the hair, milking for 30 seconds, followed by rinsing for 30 seconds. Excess water is squeezed out of the Hair Switch.

[0038] Preparation of Rinse-Off Treatment Composition: The rinse-off treatment composition can be prepared by any conventional method known in the art. A cationic surfactant and a fatty alcohol are mixed together and heated to about 66°C to about 85°C to form an oil phase. Separately, disodium EDTA, methylchloroisothiazolinone (a preservative), and water are mixed and heated to about 20°C to about 48°C to form an aqueous phase. The oil phase is mixed into the aqueous phase under high shear to form a gel matrix. The remaining components are added to the gel matrix with stirring. The composition is then cooled to room temperature.

[0039] Rinse-off Hair Treatment Protocol: All tests are performed on Caucasian virgin hair switches having a weight of approximately 2.0 grams and a length of approximately 6 inches. Hair switches are commercially available from IHIP (International Hair Importers). Three hair switches are used per dose of rinse-off composition. Each hair switch is washed with a clarifying shampoo, followed by treatment with a rinse-off conditioner according to the following protocol:

[0040] A 0.20 g amount of clarifying shampoo is spread onto each hair switch with a syringe. That is, the shampoo dosage is 0.10 g per 1 g of hair. Each application consists of applying the shampoo to the hair, milking for 30 seconds, followed by rinsing for 30 seconds. Excess water is squeezed out of the hair switch, and then 0.1 g / g of rinse-off hair treatment is applied, milked for 30 seconds, left on the hair for 15 minutes, and then rinsed with water for 30 seconds.

[0041] Oil Transfer from Scalp Mimic to Hair Switch: A rectangular scalp surface mimic (Bio Skin Plate #F-1, made of polyurethane elastomer material, 192 mm long, 129 mm wide, and 5 mm thick, manufactured by Ohken Co., Ltd., Japan) was obtained, washed with a 15% SLS aqueous solution, and air-dried. 0.38 g of artificial sebum (manufactured by Advanced Testing Laboratories, Cincinnati) was applied using a finger glove and gently pressed down to completely spread the scalp mimic to cover the entire area. A treated or untreated hair was placed on the scalp mimic, and another scalp mimic was placed on the hair switch so that the hair switch was sandwiched between the two scalp mimics. Light pressure was applied for 5 seconds, and then the hair was used to measure the amount of oil transferred from the scalp mimic onto the hair using FTIR or a Sebumeter (SEBUMETER® SM 815, Courage+Khazaka electronic GmbH). The % amount of oil transferred from the scalp mimic to the hair switch was calculated as follows: A = Amount of oil measured using a Sebumeter on hair treated with a composition containing a hydrophilic polymer and / or a cationic surfactant B = oil content measured using a Sebumeter on hair treated with a vehicle that does not contain a hydrophilic polymer and / or cationic surfactant Oil transfer from scalp simulant to hair % = [(BA) × 100] / B

[0042] Evaluation method Hair switches treated with shampoo, rinse-off conditioner, scrub, and leave-on treatment compositions are evaluated using the following methodology before and after oil transfer using a scalp mimetic.

[0043] a. Fourier transform infrared (FTIR) spectroscopy measurements After braiding the hair switch, measurements were taken at six different positions in the center of the switch using a mid-IR ATR-FTIR (Perkin Elmer Frontier FTIR equipped with a Specac Golden Gate single-bounce diamond crystal ATR accessory). The measurement range was 8 scans and 4 cm. -1 Spectral resolution is measured in absorption mode from 4000 to 600 cm -1 The ATR clamp pressure was controlled using a fixed pressure torque of 70 Ncm for all hair switch measurements. A MATLAB-based code was used to analyze the spectra and preprocess them to calculate total lipids, defined as the ratio of the CH2 stretch peak area divided by the amide 2 peak area above the baseline for each individual spectrum. Preprocessing included baseline correction and vector normalization. Vector normalization was calculated from the average absorbance value of the spectra within the selected spectral range. The calculated average value was then subtracted from the spectrum, which centers the spectrum around an absorbance value of 0. Following this, the sum of the squares of all absorbance values ​​was calculated, and each spectrum was divided by the square root of this sum. The norm of the vector of the resulting spectrum was 1.

[0044]

number

[0045] The CH stretching peak area is 2946 cm -1 2837cm from the right end of -1 Below the absorption spectrum to the left end of the spectrum and 3000 cm -1 and 2700 cm -1 The amide 2 peak area is obtained from the integrated area above the linear baseline obtained from the spectral intersection at 1580 cm -1 1475cm from the right end of -1 is obtained from the integrated area under the absorption spectrum to the left edge of

[0046] b. Sebumeter measurement A hair switch (2 g, 10-inch length of Caucasian virgin or damaged hair supplied by International Hair Importers) is placed on a clean surface, and then a Sebumeter (Courage and Khazaka MPA 580 or 815 console) is used, where the cartridge entering the console establishes a blank baseline. The cartridge with the opaque film is placed in firm, intimate contact with the hair for 30 seconds until the 30-second counter reaches zero. The cartridge is reinserted into the console and the oil value displayed on the screen is recorded. Move to a new measurement section of the cartridge by depressing the cartridge slide, then lift the slide back up and place it on a new area on the hair 1 cm away from the previous measurement. Calculate the amount of oil transfer as described above.

[0047] Hair Switch Appearance Rating Method: The treated hair switches are maintained at room temperature, laboratory conditions (32-35°C, 50% RH) for 2 hours, and then 10 trained raters are asked to rate each hair switch for oiliness of hair appearance based on a 5-point scale, with 5 being the highest rating (very oily) and 1 being the lowest rating (not oily).

[0048] Formulation Examples to Evaluate the Effectiveness of Hydrophilic Polymers Leave-on treatment formulation:

[0051] Results: Formulas 2-11 show a reduction in the % amount of oil transferred from the scalp mimetic to the Hair Switch. Less oil was observed on hair treated with the higher doses of leave-on Formulas 2-11. The results of the rating of the oiliness of the hair appearance show that the addition of hydrophilic polymer and / or cationic surfactant results in a less oily hair appearance versus no treatment and Example 6.
