Description:
PERSONAL CARE COMPOSITION FOR A KERATIN SUBSTRATE COMPRISING CONDITIONING, COLOR PROTECTING AND STYLING POLYMER

FIELD OF THE INVENTION

[0001] The present application relates to a personal care composition, and, more particularly, to a personal care composition comprising a conditioning, color protecting and/or styling copolymer for a keratin substrate of hair and/or skin origin.

BACKGROUND OF THE INVENTION

[0002] Undamaged virgin hair is smooth and shiny; its cuticles on the surface of the hair lie down smoothly making the combing easy. The hair surface is also hydrophobic in nature preventing excessive water absorption during washing. When the hair is either mechanically or chemically damaged through bleaching, perming or coloring, the hair surface becomes rough and frizzy and difficult to detangle and comb. As the hair surface becomes more hydrophilic, the resulting hair fibers swell during washing, making the hair even more difficult to comb.

[0003] Current conditioning and/or styling systems for regular and damaged hair generally use one or more combinations of cationic surfactants, amphoteric surfactants, silicones, fatty alcohols, polyquatemiums, amino acids, proteins, lipids and humectants. Wet conditioning of regular or damaged hair is accomplished by neutralizing the anionic charge of the hair by positively charged surfactants and polymers and creating a hydrophobic layer from surfactant and polymers. This hydrophobic layer results in a reduction of the swelling of the hair fibers by making the hair more hydrophobic and reducing friction of the hair fibers. An overall result of wet conditioning is improved detangling, manageability and soft feel of the hair. Upon treatment with cleansing systems like shampoos, 2inl shampoos, body washes or shower gels, the combing performance, detangling properties, hydrophobicity of the hair and lubricity are not maintained sufficiently.

[0004] Further, fading of oxidative hair color is a common and frequent complaint of majority of the end-users, and wherein, the fading occurs because of our daily grooming products such as the shampoo, conditioning and styling and its associated grooming process therein. Such frequent shampoo and conditioning of hair substrate leads to significant color wash-out. The color fade occurred during hair wash is influenced by the cuticle damage of the hair, the shade of the hair color and the extent of exposure of hair to water during washing. Further, the more damage to the cuticle facilitates more color fading/leaching during hair wash, and therefore water has been determined to be responsible for most color loss during shampooing.

[0005] Accordingly, prevention of color fading/leaching is a very prominent requirement in the hair care market today. Many hair care products claim to prevent or capable of withstanding color fading of hair stresses up to certain amount of washes (e.g. up to 40 washes) or up to certain amount of time (e.g. up to 8 weeks). While many shampoos, conditioners and hair treatments has helped to prevent color fade, the best color protection products are leave-on products that need to be reapplied every time hair is washed. The rinse- off products are usually shampoo and conditioner regimens that need work together to provide adequate cleansing and conditioning to hair. Also, rinse-off products work better when used along with a leave-on product.

[0006] Further, the extent of duration for which the hair is exposed to water plays a key role in color fading; therefore, it is important to reduce said exposure duration spent in water based cleaning and conditioning of hair. The current application is designed to deliver color protection and conditioning specifically from rinse-off products.

[0007] United States Publication Number 20150297496 assigned to Hercules Incorporated discloses a personal care conditioning and/or styling composition for a keratin substrate comprising: (i) about 50 wt. % to 95 wt. % of at least one cationic or pseudo-cationic monomer selected from the group consisting of acrylamidopropyl trimethylammonium chloride (APTAC) and/or Vinylpyrrolidone (VP); (ii) about 1 wt. % to 30 wt. % of at least one anionic monomer selected from the group consisting of (a) acrylic acid (AA), (b) acrylamido methylpropyl sulfonate (AMPS), and/or (c) sodium methyl allyl sulfonate (SMAS); and (iii) about 0.1 wt. % to 20 wt. % of at least one hydrophobic monomer selected from the group consisting of (a) polyoxyethylene (PEG)-18-behenylether-methacrylate (BEM) (b) Lauryl-ethoxylated-methacrylate (LEM), (c) stearyl acrylate (SA), (d) Stream- 10- allyl-ether, (e) Vinylcaprolactam (V-cap), and/or (f) Hydroxyethyl-pyrrolidone-methacrylate (M06). Also described is a process of preparing said polymer, and its method of use.

[0008] United States Publication Number 20110219552 assigned to ISP Investments Inc. discloses a method of protecting dyed hair color from fading or wash-out during exposure to air and/or shampooing is described. In accordance with one aspect the method includes treating dyed hair with a composition containing (i) a hydrophobically modified quaternary polymer, (ii) a hydrophobically modified polymer plus a cationic surfactant, (iii) a polymer containing diethylaminopropyl methacrylamide (DMAPMA), dimethylaminoethyl methacrylamide (DMAEMA) or diethylaminoethyl methacrylamide (DEAEMA) or (iv) a combination thereof.

[0009] Therefore, there is an increasing demand for hair care products designed to retain the properties of "virgin hair" and to prevent possible color fading during the cleansing, conditioning, chemical and mechanical treatment. In the present application, the limitations set forth above are addressed by a personal care conditioning, color-protecting and/or styling composition for a keratin substrate comprising: (A) at least one conditioning and/or styling ter/tetra polymer obtained from polymerizing: (i) about 0.1 wt.% to 99 wt. % of acrylamidopropyl trimethylammonium chloride (APT AC), a cationic monomer; (ii) about 0.1 wt. % to 30 wt. % of at least one anionic monomer selected from the group consisting of (a) acrylic acid (AA), (b) acrylamido methylpropyl sulfonate (AMPS), and/or (c) sodium methyl allyl sulfonate (SMAS); and (iii) about 0.1 wt. % to about 20 wt. % of methacryloylaminopropyl lauryl-dimethyl ammonium chloride (MAPLDMAC), a hydrophobically modified cationic monomer; (B) at least one cosmetically acceptable excipient; and (C) optionally, at least one effective amount of personal care active ingredient.

[0065] Another class of synthetic rheology modifiers and thickeners suitable for use in accordance with an embodiment of the present invention includes hydrophobically modified ASTs commonly referred to as hydrophobically modified alkali- swellable and alkali- soluble emulsion (HASE) polymers. Typical HASE polymers are free radical addition polymers polymerized from pH sensitive or hydrophilic monomers (e.g., acrylic acid and/or methacrylic acid), hydrophobic monomers (e.g., C1-C30 alkyl esters of acrylic acid and/or methacrylic acid, acrylonitrile, styrene), an "associative monomer", and an optional crosslinking monomer. The associative monomer comprises an ethylenically unsaturated polymerizable end group, a non-ionic hydrophilic midsection that is terminated by a hydrophobic end group. The non-ionic hydrophilic midsection comprises a polyoxyalkylene group, e.g., polyethylene oxide, polypropylene oxide, or mixtures of polyethylene oxide/polypropylene oxide segments. The terminal hydrophobic end group is typically a C 8 - C40 aliphatic moiety. Exemplary aliphatic moieties are selected from linear and branched alkyl substituents, linear and branched alkenyl substituents, carbocyclic substituents, aryl substituents, aralkyl substituents, arylalkyl substituents, and alkylaryl substituents. In one aspect, associative monomers can be prepared by the condensation (e.g., esterification or etherification) of a polyethoxylated and/or polypropoxylated aliphatic alcohol (typically containing a branched or unbranched Cs-Gw aliphatic moiety) with an ethylenically unsaturated monomer containing a carboxylic acid group (e.g., acrylic acid, methacrylic acid), an unsaturated cyclic anhydride monomer (e.g., maleic anhydride, itaconic anhydride, citraconic anhydride), a monoethylenically unsaturated monoisocyanate (e.g., α,α-dimethyl- m-isopropenyl benzyl isocyanate) or an ethylenically unsaturated monomer containing a hydroxyl group (e.g., vinyl alcohol, allyl alcohol). Polyethoxylated and/or polypropoxylated aliphatic alcohols are ethylene oxide and/or propylene oxide adducts of a monoalcohol containing the C8-C40 aliphatic moiety. Non-limiting examples of alcohols containing a C 8 - C40 aliphatic moiety are capryl alcohol, iso-octyl alcohol (2-ethyl hexanol), pelargonic alcohol (1-nonanol), decyl alcohol, lauryl alcohol, myristyl alcohol, cetyl alcohol, cetyl alcohol, cetearyl alcohol (mixture of C16-C18 monoalcohols), stearyl alcohol, isostearyl alcohol, elaidyl alcohol, oleyl alcohol, arachidyl alcohol, behenyl alcohol, lignoceryl alcohol, ceryl alcohol, montanyl alcohol, melissyl, lacceryl alcohol, geddyl alcohol, and C2-C20 alkyl substituted phenols (e.g., nonyl phenol), and the like.

[0066] Another class of synthetic and semi-synthetic rheology modifiers and thickeners suitable for use in accordance with an embodiment of the present invention includes cationically modified acrylic polymers and copolymers and cationically modified cellulose ethers. The acrylic polymers and copolymers and cellulose ethers are cationically modified via quaternization. For the acrylic polymers and copolymers, quaternization can occur by polymerizing a quaternized monomer into the acrylic polymer backbone or by post functionalizing the acrylic polymer with a quaternizing agent.

[0090] Further, certain aspects of the present invention are illustrated in detail by way of the following examples. The examples are given herein for illustration of the invention and are not intended to be limiting thereof.

[0091] Materials, Hair Color and Interpretation of results:

[0092] Materials: The medium density platinum bleached hair (6" length) from International Hair Importers was procured. The hair tresses were cut to 0.5 inches in width and weight approximately 2.97 grams. Wherein, textures and tones permanent hair color (Shade 4R, Red Hot Red) was measured using HunterLab Colorimeter.

[0093] Hair Color: Ammonia-free hair color: Textures & Tones 4R Red Hot Red (P&G); Ammonia-based hair color: Igora 6.88, Igora 5.99, Redken Chromatics 5C.

[0094] Interpreting the results: Color measurements (L*, a*, b*) were taken on each tress right after dyeing. L*, a*, b* values were measured on each tress after one, three, five and ten wash/treatment cycles. These values were compared to the initial L*, a*, b* values for the tress, and ΔΕ* was calculated for each tress. Each tress served as its own control. 10 measurements were taken for each tress. ΔΕ* was calculated based on the initial value of the tress. The ΔΕ* reported is the average ΔΕ* for 3 tresses. The smaller the ΔΕ* value, the smaller the color change, and better the color protection.

ΔΕ* - VAL* + \;r +Ab*

Where: AL* = L* T - L*initiai; Aa* = a* T - a*Mtiai; Ab* = b* T - b* Initial

% Color protection 100

[0095] Platinum bleached hair was chosen as the ideal hair to test color protection, because bleached hair loses more color faster than undamaged hair. Hair that has been undergone additional chemical treatment prior to coloring is more porous and the surface is more damaged than undamaged hair or non-chemically damaged hair.

[0096] Hair tresses have been colored with Textures and Tones 4R and washed with control shampoo a total of 10 times. Below are the ΔΕ* values that reflect the color change for the chemically untreated vs. bleached hair tress (Table 1). The bleached hair tress lost 62% more color after 10 washes than the undamaged hair.

Table 1: ΔΕ* Values

No of washes AE*Brown Hair AE*Bleached Hair

5x wash 1.97 6.14

lOx wash 5.34 8.68

[0097] It should be noted that the polymers are meant to be used in combination with other cationic ingredients. To this end, we tried the color protection performance in conditioner bases that are mimic finished formulas and tried the performance of the terpolymer in finished commercially available compositions. Such commercial compositions are typically a combination of alkyl quaternary ammonium compounds (e.g. Cetrimonium Chloride, Behentrimonium Chloride) to provide the conditioning benefit and silicones (such as dimethicone) to provide conditioning and color protection benefit. Further, it is important to assess the effect of the terpolymer in the presence of cationics and silicones, as this is a good indicator of its performance in finished products.

[0098] Example 1: Procedure for shampoo with conditioner regimen procedure

[0099] Rinse the hair for 30 seconds under running water (38C, 4L/min), (ii) massage with 0.5 mL shampoo into hair for 30 seconds followed by (iii) the hair was again rinsed for 30 seconds, (iv) apply 0.5mL conditioner onto the hair and leave on for 30 seconds (v) the hair was rinsed again for 30 seconds, (vi) the hair was air dried or the hair tress was kept in 50C oven for 2 hours to dry, and (vii) repeat the above steps (i - vi) for ten times (Table 2 and Table 3). Table 2: Test shampoos and conditioners compositions used in experiments

Table 3: Conditioner compositions used in experiments

[00100] Example 2: Evaluation of Color protection with various polymers [00101] Polymers having various monomer ratios were evaluated to optimize polymer for color protection benefits, and wherein, the preferred or representative ratio of APTAC/AMPS/MAPLDMAC for the present application is from about 97.7/ about 0.5/ about 1.8 (Table 4).

Table 4 - Polymer Compositions with varying monomer ratios

Polymer # Composition

(APTAC/AMPS/MAPLDMAC)

Polymer 129 97.7/0.5/1.8

Polymer 142 96.2/2/1.8

Polymer 168 93.2/5/1.8

Polymer 171 88.2/10/1.8

[00102] The hair tresses were colored with Textures & Tones 4R (Red Hot Red) hair color, air dried for 48 hours and then treated with one of the following regimen:

Control Regimen = Control Shampoo + Control Conditioner

Regimen A Shampoo A + Conditioner A (containing Polymer 129)

Regimen B Shampoo B + Conditioner B (containing Polymer 142)

Regimen C: Shampoo C + Conditioner C (containing Polymer 168)

Regimen D Shampoo D + Conditioner D (containing Polymer 171)

Table 5: Color Protection results with different monomer ratios

[00103] Shampoo and conditioner regimens containing polymers have demonstrated very good protection as compared to the regimen that did not contain any polymer (Table 2). The best color protection results were achieved with regimen that contained Polymer 129. The color protection test results are provided in Table 5 and Figure 1.

[00104] Example 3: Hydrophobicity determination by contact angle measurement

[00105] Contact angle is the indication of the surface hydrophobicity of hair. The immediate and long-lasting hydrophobicity of the terpolymers were studied by measuring the contact angle. The higher the contact angle the more hydrophobic is the surface. The undamaged virgin brown hair is naturally hydrophobic, but all the chemical treatments such as bleaching reduce the hydrophobicity of the hair. Contact angle was determined for tresses that were washed and conditioned lOx with Regimen A (containing Polymer 129) and control regimen. The method is as follows: A portion of the hair tress was stretched on a specially designed plate so that the fibers were suspended together in space to form a "single" surface. The image analysis and measurements were done with Kruss drop shape analysis system DSA-10. A droplet of deionized water was delivered from a syringe onto the fiber surface. Droplet mass is -0.004 g. Images and measurements were collected at 0 seconds and in 20 second intervals until the droplet was completely absorbed by the hair and the contact angle was 0. The regimen containing polymer significantly improved the contact angle of bleached and dyed hair after lOx treatment (Table 6). The improvement in contact angle is an indication of the improvement of the condition and hydrophobicity of hair surface. It also indicates that the polymer effectively deposits onto the hair surface and it is substantive to form a hydrophobic film on the hair surface to help prevent leaching of hair color. The hydrophobicity test results are provided in Table 6 and Figure 2.

Table 6 - Contact angle measurements

[00106] Wherein, the contact angle measurements of bleached and dyed hair treated with control shampoo and conditioner regimen, bleached and dyed hair treated lOx with shampoo and conditioner regimen containing polymer, and virgin hair (without any treatment).

[00107] Example 4: Conditioning Evaluation - combing force test

[00108] To determine the conditioning properties of the polymer - bleached hair (low density, 1" with, 10" length, purchased from International Hair Importers) was treated with shampoo and conditioner. [00109] The combing force on wet hair was measured with an Instron combing machine. For the baseline measurements, the hair was cleaned with a 4% SLES solution, rinsed, and the combing force was measured on clean hair. The hair was then treated with either the control shampoo or a shampoo containing the polymer. After shampoo was rinsed from the hair, combing force was measured again. Conditioner was applied to hair (0.2 gm conditioner/gm hair), rinsed and combing measurements were taken. Hair was then shampooed again (with the appropriate shampoo for the regimen), and the combing force was measured again. The compositions of Table 7 and Table 8 were used for this styudy.

Control regimen = control shampoo + control conditioner (no polymer)

Regimen E: Shampoo E (0.2% Polymer 129) + Conditioner E (1% polymer) Regimen F: Shampoo F (1% Polymer 129) + Conditioner E (1% polymer)

[00110] The higher the combing force, the more difficult it is to detangle and comb hair. High combing forces indicate a rough hair surface, and lack of conditioning.

Table 9 - Combing force data for shampoos (gf-mm)

[00111] From Table 9 and Table 10 and Figure 3-4, the addition of polymer to the shampoo caused an immediate and significant reduction in combing force, indicating very efficient conditioning of polymer.

Table 10 - Summary of combing force data for Shampoo + Conditioner regimen

[00112] Further, it is evident from the above results that the incorporation of polymer provides significant conditioning from both shampoo and conditioner regimens, particularly from shampoo regimen. Washing hair with the shampoo after the conditioner improves the condition of the hair. This indicates that consumers could potentially skip the conditioner at least once, and still have excellent manageability and combing of hair.

[00113] Example 5: Color protection with different shades

[00114] Platinum blonde hair tresses were dyed with various shades. The tresses were then treated with Regimen A, Regimen B or Control regimen (Table 11, Table 12 and Table 13).

Table 11: Color Protection test with Igora

Example 6: Color Protection comparison with commercial shampoo/conditioner Table 14: Color protection of commercial sample A

Table 15: color protection with commercial sample B

Table 16: Color protections with Commercial sample C

[00116] As seen from the results, the polymer enhanced the color protection benefit of commercial color protection shampoos and conditioner (Table 14, Table 15, and Table 16).

[00117] Example 7 - Styling and manageability in leave-on products

[00118] The ability of a polymer to help create and maintain the style of hair is very important.

[00119] Polymers were evaluated on 10 in long, 1 in wide hair virgin brown hair tress from International Hair Importers (IHIP). Tress were washed with a clarifying shampoo and air dried. Each tress was applied 0.5 gr of the designated 1% active polymer solution and distribute on the tress for 60 seconds. Tress were rolled onto a hair roller (2¾" x ¾") to create curl. Air dry hair on rollers in 40°C oven for 24 hours. Let tress equilibrate on rollers at room temperature for 1 hour before evaluation. Tresses were evaluated by 7 trained evaluators. Each evaluator was provided with a set of tresses, instructions on how to evaluate, scoring sheets and combs (one for each treatment). The evaluators took the hair off the rollers and hanged them for evaluation. The results were tallied and the average scores were provided.

[00120] Polymer 129 provides very good conditioning, manageability, ease of combing in leave- on treatment. It also imparts flexibility and resilience to hair as seen in the Table 17. Polymer 129 leaves a flexible film on the hair, which allows it to retain much of the stiffness and help the curl bounce back. Traditional styling polymers, are initially stiffer, but that stiffness and flexibility diminish over time.

[00121] Surprisingly, Polymer 129 provides very good static control to dry hair. One drawback of cationic polymers with high charge density is the build-up of electrostatic charge along the hair fiber. When hair is brushed or combed, especially at low humidity, the charged hair fibers repel each other, resulting in flyaway ("static"). Polymer 129, however, while having a high positive charge density, provided the best static control (less flyaway) than the other polymers evaluated.

Table 17 - Polymer 129 Evaluation

[00122] Example 8: Curl holding and defining properties on frizzy hair

[00123] Polymer 129 was evaluated in a high humidity curl retention study to see the effect of polymer on curly frizzy hair. Hair was purchased from IHIP, and divided into 6" long/1" wide segments. 0.35 grams of 1% solution was applied to cleaned hair and distributed on hair for 60 seconds. Hair was rolled on 5/8" mandrel to create curl. Hair was removed from mandrel and curl was secured with a clip, then put into a 40°C oven for 24 hours. After 24 hours, hair removed from oven. Clips were also removed, and hair was hung curl retention boards and placed in humidity chamber (80°F and 90% relative humidity).

[00124] Curl drop was evaluated at 30 minute intervals for 4 hours.

[00125] All polymers showed very good curl retention at high humidity. Being a conditioning polymer, Polymer 129 imparts a soft, flexible hold to curly hair. Polymer 129 also showed very good curl definition and curl control at high humidity, comparable to traditional styling polymers (FIG 6).

[00126] Example 9: Color rejuvenation

[00127] A mannequin head was bleached and then colored with Textures & Tones 4R (Red hot red) hair color. The mannequin was washed and conditioned 12 times, to simulate fading. After 12 shampoo/conditioner regimen, a 1% active solution of Polymer 129 was applied to the hair. The color was evaluated with hyperspectral imaging

[00128] This new technique expands on classical imaging by combining photography with spectroscopy. Where classical imaging gives a picture in which each pixel is defined by 3 values (Red, Green, Blue), hyperspectral imaging will provide a picture in which each pixel contains an entire spectrum of values for each wavelength of the integrated spectroscope. In our case, a Headwall Photonics G4-395 camera provided us with a spectrum coverage from the near UV (380nm) until the mid-infrared (988nm). By calibrating the camera for light source spectral intensities, we can obtain the exact spectral reflectivity spectrum of a surface, in our case, hair swatches. Lighting is placed laterally at 40 degrees from the imaging axis to avoid shine and bring out color. The absorbance spectra are shown in Figure 5.

[00129] Each hair color (pigment) has a unique spectral absorbance signature. The higher the spectral absorbance of the red pigment, the more intense/saturated is the pigment color. Treatment with Polymer 129 increases the saturation of the red pigment, as it effectively re-saturates the red color.

[00130] The blue line in Figure 6 shows the difference between the absorption of faded hair treated with Polymer 129 and untreated hair. This line is the absorption profile of the red pigment, shows enhancement of the color pigment (FIG.7 and FIG. 8).

[00131] Example 10: Enhancing diameter of hair, volumizing effect

[00132] The diameter of bleached hair was measured before dyeing, after dyeing, and after 1 and 5 treatments with either the control regimen of regimen F (Table 10).

[00133] The results below clearly show that the diameter of the hair treated with Regimen F has increased the diameter of the hair.

[00134] Polymer 129 forms a film on hydrophobic film on hair to help prevent water/moisture going in and of hair. Some moisture may get trapped inside the hair shaft, unable to escape due to the hydrophobic polymer film. In addition, the polymer itself also forms a uniform film on hair. Consequently, the diameter of the hair treated with Regimen F has shown an increase compared to the control regimen (Table 10).

[00135] There is a trend of decreasing cross section diameter for the control tress. This could be explained by further damage to the hair (eg. cuticle removal) during the washing and conditioning cycle (FIG. 9).

[00136] The increase in the diameter of the hair also resulted in a perceived volumizing effect for Regimen F.

[00137] During a ½ head evaluation on a mannequin, evaluators rated volume of the side treated with Regimen F higher than the side treated with the control regimen. Evaluators also perceived the side treated with Regimen F as having more hair. (FIG. 10)

[00138] While this invention has been described in detail with reference to certain preferred embodiments, it should be appreciated that the present invention is not limited to those precise embodiments. Rather, in view of the present disclosure, which describes the current best mode for practicing the invention, many modifications and variations would present themselves to those skilled in the art without departing from the scope and spirit of this invention.
