Description

Title of the invention: Cosmetic and personal care compositions containing cationic surfactants and anionic compounds Field of disclosure

[0001] The present disclosure relates to cosmetic and personal care compositions containing cationic surfactants, anionic compounds selected from anionic polymers and fatty compounds. The compositions are particularly useful for imparting conditioning or moisturizing properties to keratinous substrates such as hair or skin and exhibit improved rinsability properties. Also disclosed are methods of using the cosmetic compositions. CONTEXT

[0002] Many consumers desire to use cosmetic and personal care compositions that impart conditioning and moisturizing properties to keratinous substrates such as hair and skin. For example, consumers continually seek skin and scalp care products that can provide enhanced conditioning and moisturizing benefits. They also seek hair care products or cosmetic hair compositions to care for hair that has been subjected to chemical treatments such as oxidative dyes, hair straighteners, or permanent wave treatments. Many of these chemical treatments are alkaline in nature and may leave residual alkalinity on the treated hair.

[0003] Although dyes or color changing compositions can effectively change the color of hair, and straightening, smoothing, perming, and waving compositions can effectively change the shape of hair, these chemical treatments can damage hair fibers and / or irritate the scalp. In addition, external factors such as high humidity, which makes hair very frizzy, difficult to style, and causes it to lose its shape and style, or mechanical, physical, or other stresses, such as brushing, combing, tangling, and heat, can also damage or negatively impact the feel and appearance of hair.

[0004] Thus, in order to reduce or avoid damage to the hair, as well as to improve the cosmetic performance of the compositions, different types of hair products have been developed by manufacturers with the aim of helping consumers improve hair quality, hair feel and hair management. reliability as well as reducing or eliminating hair frizz and conditioning / moisturizing hair, especially when damaged. These products are typically supplied as shampoos, conditioners, or treatments such as after- or pre-shampoo treatments, and after- or pre-conditioning treatments which may be leave-in or rinse-out products.

[0005] Additionally, consumers desire hair and skin care products, particularly rinse-off cleansing and conditioning products, that can be removed quickly or efficiently without leaving noticeable residue and that, at the same time, provide conditioning, moisturizing, or other cosmetic benefits such as improved hair or skin feel.

[0006] Thus, the subject matter of this invention relates to a composition and method for treating keratinous substrates such as hair or skin, wherein the composition provides both care and rinsability / removability properties.

[0007] The object of the invention is also to provide a composition and a method for treating hair that has been chemically treated or damaged, such as hair that has been contacted with a basic or alkaline treatment, summary of the disclosure

[0008] It has surprisingly been found that the compositions and methods for treating keratinous substrates such as hair or skin according to the present invention provide conditioning and moisturizing benefits to the keratinous substrate, as well as other desirable properties such as rapid and effective rinsability or removability attributes.

[0009] One aspect of the invention relates to a cosmetic composition containing:

[0010] (a) at least 0.3% by weight, relative to the total weight of the composition, of at least a non-hydrophobically modified anionic polymer;

[0011] (b) at least one cationic surfactant, including a cationizable surfactant;

[0012] (c) at least one fatty alcohol; and

[0013] (d) at least one cosmetically acceptable solvent;

[0014] wherein the pH of the composition is less than about 5.

[0015] Another aspect of the invention relates to methods of treating keratinous substrates such as hair or skin, for example, conditioning or moisturizing hair or skin. In some embodiments, the method comprises applying any of the compositions described herein to keratinous substrates. In one or more embodiments, the composition is applied to hair, including curly hair, as part of a hair care routine. In some embodiments, the composition is applied after shampooing the hair. In some embodiments, the composition is a rinse-off product. In some embodiments, the rinse-off composition is used as a post-treatment product, after chemically treating the hair or treating the hair with an alkaline product. Such a product can provide conditioning, moisturizing, and repair benefits to chemically treated hair. In some embodiments, the composition is used as a rinse-off skin care product that can cleanse and, at the same time, provide conditioning and moisturizing benefits. Brief description of the drawings

[0016] The implementation of the present technology will now be described, by way of example only, with reference to the attached figures, in which:

[0017] [Fig. 1] [Fig. 1] includes graphs showing that the viscosity of the inventive composition changes significantly while the viscosity of a comparative composition does not change significantly when the pH of each composition is increased.

[0018] [Fig. 2] [Fig. 2] includes graphs showing that the viscosity of the inventive composition changes significantly while the viscosity of a comparative composition does not change significantly when each composition undergoes a 3x dilution with water.

[0019] [Fig.3] [Fig.3] includes photographs of strands of hair treated with the inventive composition and the comparative composition immediately after (initial) treatment and after two days in a humid chamber at 80% relative humidity.

[0020] [Fig.4] [Fig.4] includes photographs of strands of hair treated with the comparative composition and the inventive composition immediately after (initial) treatment and after two days of air drying.

[0140] When the cosmetic composition is brought into contact with external water, the viscosity of the composition decreases, which makes it possible to improve the spreading and ease of application of the composition to the skin or hair.

[0141] In various embodiments, when the cosmetic composition of the present disclosure is to be applied to hair, any of the methods described above includes applying the cosmetic composition to hair that has been previously contacted or pretreated with an alkaline or basic product or composition, including an oxidative hair dye composition or a hair straightening / smoothing composition.

[0142] It has also been surprisingly discovered that the combination of the at least one non-hydrophobically modified anionic polymer and the at least one cationic surfactant in a composition for treating hair, resulted in faster and improved rinsing ease of the composition when the pH of the composition is increased, such as when the composition is contacted with an alkaline or basic composition or substrate or when the composition is applied to pre-alkalized hair. As the pH of the composition increases, the viscosity of the composition decreases significantly. With faster and improved rinsing ease, the rinsing step uses less water.

[0143] Thus, in one embodiment, the present invention further relates to a quick wash or quick rinse method, the method comprising applying to pre-alkalized hair or hair having a basic or alkaline pH, a cosmetic composition comprising:

[0144] (a) about 0.3% by weight, relative to the total weight of the composition, of at least a non-hydrophobically modified anionic polymer;

Amino-functional silicones

[0234] The silicones may be hydrophobic or, in some cases, may be functionalized to be hydrophilic. Preferably, the silicones in the hair treatment compositions are amino-functional silicones. The term "amino-functional silicone" means a silicone containing at least one primary amino, secondary amino, tertiary amino, and / or quaternary ammonium group. The structure of the amino-functional silicone may be linear or branched, cyclic or non-cyclic. The amino functional group may be at any position in the silicone molecule, preferably at the end of the backbone (e.g., in the case of amodimethicones) and / or in the side chain.

[0235] In certain cases, the amino-functional silicones are chosen from compounds of the following formula:

[0237] wherein each R1 is independently selected from a C1-30 alkyl group, a C1-30 alkoxy group, a C5-30 aryl group, a C6-30 aralkyl group, a C6-30 aralkyloxy group, a C1-30 alkaryl group, a C1-30 alkoxyaryl group and a hydroxy group (preferably, each R1 is independently selected from a C1-30 alkyl group, a C1-30 alkoxy group and a hydroxy group);

When z is 1, the amino-functional silicone may have only terminal amine-functional substituents (e.g., m=0) or may have both terminal and pendant amine-functional substituents in the polymer chain (e.g., m>0). Preferably, n + m is 50 to 1000.More preferably, n + m is from 50 to 750. Even more preferably, n + m is from 50 to 500. Most preferably, n + m is from 50 to 250. In some cases, the amino-functional silicones are alkoxylated and / or hydroxylated amino silicones. Suitable alkoxylated and / or hydroxylated amino silicones may be selected from compounds having a structure according to the following formula: in which R3 is hydroxyl or OR5, R5 is a C1-C4 alkyl group, R4 is a group having a structure according to the following formula: - CH2 CH CH2 NH (CH2)n NH2 ' D in which R6 is a C1-C4 alkyl group, n is 1 to 4, x is the same as “n” described above, and y is identical to “m” described above.

In particular, when the cosmetic compositions are intended to be applied to hair, i.e., they are hair cosmetic compositions, the methods generally comprise applying to the hair any of the hair cosmetic compositions described. The hair cosmetic compositions may be useful in a variety of contexts, and either for chemically treated or pre-alkalized hair or for untreated hair. Pre-alkalized hair may include chemically relaxed / straightened or chemically dyed (with oxidative dyes) or bleached or lightened / highlighted hair, i.e., hair treated with products that result in an increase in the pH of the hair to an alkaline pH.Use of the compositions of the present invention on hair may include as part of a shampoo, part of a conditioner or as a conditioner, as a pre-treatment, or after cleansing or conditioning or washing the hair, or as a treatment for the care of curly hair or as a mask treatment with or without rinsing.

[0284] Methods of treating hair according to the disclosure may include applying a hair cosmetic composition of the present disclosure to the hair (wet, damp, or dry hair), leaving the hair treatment on the hair for a sufficient period of time, and rinsing the hair cosmetic composition or leaving the hair treatment on the hair as a leave-in product. The hair cosmetic composition may be applied to the hair before, during, or after other hair cosmetic compositions (e.g., shampoo, conditioner, mask, cream, lotion, gel, etc.)

[0285] The hair cosmetic composition may remain on the hair for a period of time, for example from about a few seconds (1, 3, 5 or 10 seconds) to about 10, 20 or 30 minutes, or longer, for example up to about one hour, or until about two o'clock, or until about three o'clock, or until about four o'clock, or until about five o'clock, or until about six o'clock, or until about seven o'clock, or until about eight o'clock, or until about twelve o'clock or all night.

[0286] Hair cosmetic compositions may be useful for treating chemically treated hair.

[0287] The individual application of a hair cosmetic composition or the combined or layered application of a hair cosmetic composition with another composition is described above. In some cases, a hair cosmetic composition is applied individually to the hair and is also combined or layered with another composition that is also applied to the hair. Kits

[0288] The cosmetic compositions of the present disclosure may be incorporated into a kit. For example, the kits may include at least one cosmetic composition according to the present disclosure. The kits may also include one or more hair cosmetic compositions (according to the present disclosure), such as a shampoo and / or a conditioner and / or a mask and / or another hair treatment or styling product.

[0293] Process for manufacturing the compositions of the invention:

[0294] Invention example A was prepared according to the following general process:

[0295] The formulation was prepared by:

[0296] - heating the water to approximately 70°C,

[0297] - then addition of cetearyl alcohol, amodimethicone and behenyl chloride- trimonium until completely dispersed,

[0298] - cooling to about 50°C,

[0299] - addition of acrylate copolymer, other optional additives (preservatives, solvent organic, surfactants, perfume and dyes, etc.)

[0300] - then continued cooling to room temperature.

[0301] The pH of the inventive formulas made according to the above method ranged from about 2.5 to less than 5. The inventive formulas obtained were also stable after 2 months at 45°C and 4°C, respectively, i.e. there was no phase separation or precipitation, even with the combination of a cationic compound (cationic surfactant) and an anionic compound (acrylate copolymer) in the formulas.

[0302] Example II: Viscosity, dH and dilution studies

[0303] The following table shows the changes in the properties of the inventive formulations such as texture and viscosities when their pH was changed or when the formulations were diluted with water. The viscosities of the formulations were measured using a rheometer (DHR-2, TA instruments, New Castle, DE, USA) and a 40 mm parallel plate geometry. A gap of 1 mm between the parallel plates was chosen. All tests were carried out at 25°C and atmospheric pressure. The sample was subjected to a shear ramp starting from 0.1 1 / s up to 1000 1 / s in a period of 300 seconds. The time interval between data points is 1 s. The shear stress response was recorded for each data point.

[0304] The pH of the formulations was modified or adjusted by adding sodium hydroxide solution or other suitable pH modifiers.

[0305] The textures of the formulations were evaluated using a polarized microscope.

[0311] * External water means water that is not part of the formulation when it is initial preparation.

[0312] The data in Table 3 can be viewed in Figures 1 to 2. In Figure 1A, it can be seen that the viscosity of the inventive composition, Ex. A, significantly decreased over a shear rate of 10 to 1 x 103 1 / s when the pH of the inventive composition Ex. A was increased to greater than 5, i.e., to about 5.6. Thus, while the inventive composition initially has a higher viscosity or is thicker, which prevents or reduces drainage of the composition upon application to a substrate such as hair, a change in the pH of the composition resulting in a significant decrease in viscosity allows for easier spreading and application to the surface such as hair fibers, resulting in better and homogeneous deposition of the active agents and / or conditioning agents and / or styling agents on the surface.At the same time, the decrease in viscosity makes it easier and faster to rinse or remove the composition. hair with water (quick wash or rinse effect or improved rinsability). The cleaning or rinsing process would therefore require less water.

[0313] Thus, when the inventive composition is exposed to an alkaline or basic environment, for example when mixed with an alkaline composition or when applied to chemically treated hair (or pre-alkalized hair) that has been previously treated with hair dyes or hair relaxers that are typically alkaline and typically have residual alkalinity, the pH of the inventive composition may increase, thereby resulting in a significant decrease in viscosity that facilitates spreadability, ease of application, and more even application of the composition to a substrate.The significant decrease in viscosity due to the increase in pH of the composition is associated with the unique and improved rinsing ability or removal capability or rapid washing / rinsing property of the instant disclosure compositions (requiring less water during rinsing).

[0314] In contrast, a very small or insignificant viscosity change was observed for the comparative composition, Ex. B, even when its pH was increased to more than 5, i.e., to about 5.5 (FIG. 1B). This insignificant viscosity change was evident for a shear rate range from 10 to 1 x 103 1 / s; such a result indicates that the spreading and application attributes of the composition onto a substrate and / or the rinsing property of the composition from a substrate would not be significantly affected.

[0315] As for the dilution of the inventive composition with water, for example by a 3x dilution with water, its viscosity decreases significantly compared to the initial viscosity of the composition (FIG. 2A). The decrease in viscosity allows for easier spreading and application of the composition to a surface such as the surface of hair fibers, which allows for a homogeneous and better deposition of the active agents and / or conditioning agents on the surface. The decrease in viscosity also allows for easier and faster removal of the composition from the surface (fast washing or rinsing effect or improved rinsability). The cleaning or rinsing process would therefore require less water.Thus, the decrease in viscosity due to dilution, which mimics application to wet hair and / or the addition of external water, is associated with the unique and improved property of rinsability or removability or rapid washing / rinsing of the compositions of the present disclosure (requiring less water during rinsing).

[0316] In contrast, comparative composition Ex. B, exhibited only a very slight change in viscosity upon dilution with water over a shear rate ranging from 10 to 1 x 103 1 / s (FIG. 2B); such a result indicates that the spreading and application attributes of the composition on a substrate and / or the property of rinsability of the composition from a substrate would not be significantly affected.

[0317] In conclusion, the inventive composition has been found to be sensitive to a change in pH and / or dilution with water which results in a significant decrease in viscosity. This change in viscosity can result either from applying the composition to pre-alkalized hair or from diluting it with water (as in hair cleansing or conditioning activities). The resulting decrease in viscosity impacts the spreadability and application of the composition to a surface such as hair. As the viscosity decreases, the composition becomes easier to spread and apply to the surface and to remove or rinse / wash from the hair. Example III: Studies of hair strands

[0318] The inventive composition Ex. A and the comparative composition Ex. B were each applied to locks of wet hair of medium degree of curl. The locks were pre-shampooed, rinsed with water, treated with the inventive composition or the comparative composition, then rinsed with water.

[0319] In a study, wet strands were placed in a humid chamber (80% RH) at 25 degrees centigrade for 2 days. Figure 3A (left image of [Fig.3]) shows the visual appearance of the strands before placing them in the humid chamber. The left strand was treated with the inventive composition Ex. A and the right strand was treated with the comparative composition Ex. B (initial). Figure 3B (right image of [Fig.3]) shows the visual appearance of the strands after 2 days in the humid chamber (after 2 days). It is evident from the images that at the initial stage, the strand treated with the inventive composition was less frizzy, had better definition and curl shape and had a smoother appearance compared to the strand treated with the comparative composition. The inventive composition and the comparative composition imparted a comparable conditioning effect to the hair.It was also evident that after 2 days in high humidity, even though the strand treated with the inventive composition was more voluminous compared to the initial stage, it was significantly less frizzy, had better definition and shape of the curls and had significantly less volume compared to the strand treated with the comparative composition.

[0320] In another study, wet strands were allowed to air dry at 25 degrees centigrade for 2 days. Figure 4A (left image of [Fig.4]) shows the visual appearance of the strands before air drying. The left strand was treated with comparative composition Ex. B and the right strand was treated with inventive composition Ex. A, (initial). Figure 4B (right image of [Fig.4]) shows the visual appearance of the strands after 2 days of air drying (after 2 days). On the images of the initial stage, the strands had comparable appearances - very little frizz, curl definition and shape and smooth and conditioned appearance compared to the strand treated with the comparative composition. However, after 2 days of air drying, even though the strand treated with the inventive composition was more voluminous compared to the initial stage, it was significantly less frizzy, had better curl definition and shape and had significantly less volume compared to the strand treated with the comparative composition.

[0321] Overall, the inventive composition provided a better anti-frizz effect, better curl definition, and a smooth or less voluminous appearance to natural curly hair compared to the comparative composition that did not contain the anionic copolymer.

[0322] The foregoing description illustrates and describes the invention. The disclosure shows and describes only the preferred embodiments, but it is to be understood that the invention may be used in various other combinations, modifications, and environments and may be subject to changes or modifications within the scope of the inventive concepts as expressed herein, based upon the above teachings and / or skill or knowledge in the relevant art. The embodiments described above are further intended to explain the best modes known to the applicant and to enable others skilled in the art to utilize the disclosure in such or other embodiments and with the various modifications required by the particular applications or uses thereof. Accordingly, the description is not intended to limit the invention to the form disclosed herein.

[0323] As used herein, the terms "comprising," "having," and "including" (or "comprise," "have," and "include") are used in their open and non-limiting sense. The phrase "consisting essentially of" limits the scope of a claim to the specified materials or steps and to those that do not materially affect the fundamental and novel features of the claimed invention.

[0324] Throughout the disclosure, if the phrase "a mixture thereof" is used, it follows a list of elements as shown in the following example where the letters A through F represent the elements: "one or more elements selected from the group consisting of A, B, C, D, E, F, or mixtures thereof." The phrase "a mixture thereof" does not require that the mixture include all of A, B, C, D, E, and F (although all of A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of any two or more of A, B, C, D, E, and F may be included. In other words, it is equivalent to the phrase "one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture of any two or more of A, B, C, D, E, and F."

[0325] When the disclosure refers to "a member selected from the group consisting of A, B, C, D, E, F, a salt thereof, or mixtures thereof," it indicates that one or more of A, B, C, D, and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included.

[0326] Salts mentioned throughout the disclosure may include salts having a counterion such as an alkali metal, alkaline earth metal, or ammonium counterion. This list of counterions is not, however, limiting.

[0327] The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures / combinations.

[0328] The term “plurality” means “more than one” or “two or more.”

[0329] As used herein, the term "cosmetic composition" is intended to include "personal care" compositions.

[0330] Some of the various component categories identified for the compositions of the present disclosure may overlap. In such cases where an overlap may exist and the composition / product includes two overlapping components (or more than two overlapping components), an overlapping component is not more than one component. For example, a fatty acid may be defined as both a "fatty compound" and a "surfactant / emulsifier." If a particular composition / product includes both a fatty compound component and an emulsifier component, a single fatty acid may serve solely as the fatty compound or as the surfactant / emulsifier (a single fatty acid does not serve as both the fatty compound and the surfactant / emulsifier).

[0331] All percentages, parts and ratios set forth herein are based on the total weight of the compositions of the present invention, unless otherwise indicated.

[0332] All ranges and values disclosed herein are inclusive and combinable. For example, any value or point described herein that falls within a range described herein may serve as a minimum or maximum value for deriving a subrange, etc. Furthermore, all ranges provided are intended to include each specific range within, as well as any combination of subranges between, the given ranges. Thus, a range of 1 to 5 specifically includes points 1, 2, 3, 4, and 5, as well as subranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc.; and points 1, 2, 3, 4, and 5 include ranges and subranges of 1 to 5, 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc.

[0333] Other than in the working examples, or unless otherwise indicated, all numbers expressing amounts of ingredients and / or reaction conditions are understood to be modified by "about", whether or not expressly indicated. Furthermore, all numbers are intended to represent exact figures as additional embodiments, whether or not modified by "approximately." For example, "an amount of approximately 1%" includes an amount of exactly 1%. In another example, "an amount of 1%" includes an amount of approximately 1%.

[0334] The term "surfactants" includes salts of surfactants, even if not explicitly mentioned. In other words, whenever the disclosure refers to a surfactant, it is understood that salts of the surfactant are also included to the extent that such salts exist, even though the specification may not specifically refer to a salt (or may not refer to a salt in every instance throughout the disclosure), for example, by using language such as "a salt thereof" or "salts thereof." Sodium and potassium are common cations that form salts with surfactants. However, other cations, such as ammonium ions or alkanolammonium ions, such as monoethanolammonium or triethanolammonium ions, may also form surfactant salts.

[0335] The term "substantially free" or "essentially free" as used herein means that the specific material may be present in small amounts that do not materially affect the fundamental and novel features of the claimed invention. For example, there may be less than 2% by weight of a specific material added to a composition, based on the total weight of the compositions (provided that an amount less than 2% by weight does not materially affect the fundamental and novel features of the claimed invention). Similarly, the compositions may include less than 2% by weight, less than 1.5% by weight, less than 1% by weight, less than 0.5% by weight, less than 0.3% by weight, less than 0.1% by weight, less than 0.05% by weight, or less than 0.01% by weight, or none of the specified material.

[0336] The term "substantially free" or "essentially free" as used herein may also mean that the specific material is not added to the composition but may still be present in a starting material that is included in the composition.
