Description

Technical Field

[0001] This invention relates to a rinse-out hair cosmetic composition comprising: (a) at least one organic acid; (b) a non-aqueous solvent comprising at least one compound having at least one hydroxyl group; (c) at least one amino acid; (d) at least one fatty compound selected from plant oils, plant resins, plant waxes, and mixtures thereof; (e) water; and (f) at least one surfactant selected from cationic surfactants, nonionic surfactants, and mixtures thereof. The invention also relates to a method for treating hair (particularly curly hair), a method for providing improved curl definition (curls definition) to hair, and the use of the composition in the manufacture of rinse-out hair care products for improving curl definition. Background Technology

[0002] People have long used a variety of cosmetic and personal care compositions to enhance the appearance and feel of keratin fibers such as hair.

[0003] Especially for curly hair, consumers are always dealing with issues related to the characteristics of curl, such as frizz, volume, and shape. Curly hair tends to become frizzier and significantly increase in volume when exposed to high humidity conditions, chemical treatments, etc. In addition, it loses its curl shape and definition after sleeping.

[0004] Many attempts have been made to develop products to regulate, define, and control hair, especially curly hair, thereby enhancing / maintaining curl definition, curl retention, and curl regularity without making the hair feel and / or look unnatural and stiff. However, such products lead to additional problems or maintenance difficulties.

[0005] For example, current technology products typically require a large amount of product to provide good combing and hair feel. However, given that the effects of such products are not long-lasting, consumers must reapply the product multiple times throughout the day or after sleeping to regain definition and curl control. This leads to product buildup on the hair surface, resulting in a heavy appearance, wet look, unnatural touch, and greasy feel, because such products do not penetrate into the keratin fibers but remain on the surface of the hair fibers.

[0006] In this sense, the market needs a curly hair product that defines curls in a lasting way, does not require reapplication before the next wash or after sleeping, and reduces the need to use large amounts of the product between washes.

[0007] In addition, the standard curly hair care routine involves using multiple cosmetic products along the entire length of the hair and must be repeated every two days because after such a period, the curls tend to lose their definition and new look—it is a very time-consuming process that involves consumers restarting all the steps approximately every two days, including washing the hair and applying different cosmetic products.

[0008] Therefore, there is a need for a rinse-out hair cosmetic product for curly hair that not only helps to define curly hair but also provides consumers with long-lasting cosmetic benefits such as anti-frizz, maintaining shine, ease of application, and no feeling of dampness or heaviness when using such a product. There is also a need for a rinse-out hair cosmetic product for curly hair to reduce the amount of cosmetic used by the consumer and to prolong the effects of the composition so that consumers can gain an extra few days before having to restart their curly hair cosmetic care routine.

[0009] The inventors of this invention have surprisingly and unexpectedly achieved a rinse-out hair cosmetic composition specifically designed for curly hair, comprising: (a) at least one organic acid; (b) a non-aqueous solvent comprising at least one compound having at least one hydroxyl group; (c) at least one amino acid; (d) at least one fatty compound selected from plant oils, plant resins, plant waxes, and mixtures thereof; (e) water; and (f) at least one surfactant selected from cationic surfactants, nonionic surfactants, and mixtures thereof. This composition not only penetrates into the hair fiber without accumulating on the fiber surface, but also provides curl definition, long-lasting curl definition, frizz control, natural appearance, and desired volume before the next wash, without feeling heavy on the hair, and also provides cosmetic benefits such as shine, smooth touch, and flexibility. Summary of the Invention

[0010] This invention relates to a rinse-out hair cosmetic composition comprising: (a) at least one organic acid; (b) a non-aqueous solvent comprising at least one compound having at least one hydroxyl group; (c) at least one amino acid; (d) at least one fatty compound selected from plant oils, plant resins, plant waxes, and mixtures thereof; (e) water; and (f) at least one surfactant selected from cationic surfactants, nonionic surfactants, and mixtures thereof. The invention also relates to a method for treating hair, particularly curly hair, comprising the step of contacting the hair with the rinse-out hair cosmetic composition of the invention. The invention further relates to a method for providing improved curl definition in hair, comprising contacting the hair with the rinse-out hair cosmetic composition of the invention.

[0151] As used herein, a “conditioning agent” means a product / composition capable of imparting at least one property selected from combability, moisture retention, shine, gloss, and softness to one or more hair fibers. The conditioning state can be assessed by any means known in the art, such as, for example, measuring and comparing the combability (gm-in) of treated and untreated hair and consumer perception.

[0152] As used herein, the term "treatment" (and its grammatical variations) refers to applying the composition of this disclosure to the surface of hair. As used herein, the term "treatment" (and its grammatical variations) also refers to bringing the composition of this disclosure into contact with hair.

[0153] As used herein, the expression “at least one” means one or more, and therefore includes both single components and mixtures / combinations.

[0154] Unless otherwise specified in the operation, all figures indicating the amount of ingredients and / or reaction conditions shall be understood to be modified by the term “about” in all cases, meaning within + / - 5% of the figures shown.

[0155] As used herein, all ranges provided are intended to include each specific range within a given range, as well as combinations of subranges therein. Thus, the range 1-5 specifically includes 1, 2, 3, 4, and 5, and subranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc. All ranges and values ​​disclosed herein are inclusive and composable. For example, any value or point falling within the ranges described herein can be used as a minimum or maximum value to derive subranges, etc.

[0156] As used herein, the terms “substantially free” or “substantially free” mean that, based on the total weight of the composition, the specific material added to the composition is less than about 5% by weight. Nevertheless, the composition may contain less than about 2% by weight, less than about 1% by weight, less than about 0.5% by weight, less than about 0.1% by weight, less than about 0.01% by weight, or be free of the specified material.

[0157] As used herein, the term “active material” referring to the percentage amount of an ingredient or raw material means that the ingredient or raw material is 100% active.

[0158] "Cosmetic-acceptable" means that the item in question is compatible with the keratin matrix, such as skin and hair. For example, "cosmetic-acceptable carrier" refers to a carrier that is compatible with the keratin matrix, such as skin and hair.

[0159] As used herein, the term "hair cosmetic composition" can also refer to a hair styling or hair shaping or hair care or hair treatment composition.

[0160] The term "cationic surfactant" refers to a positively charged surfactant. Such a surfactant may carry one or more positive permanent charges, or may contain one or more functional groups that are cationic in the compositions according to the invention.

[0161] Throughout this disclosure, the term "the combination thereof" (or a mixture thereof) may be used after a list of elements, as shown in the following example, where the letters AF represent an element: "one or more elements selected from the group consisting of A, B, C, D, E, F and combinations thereof." The term "the combination thereof" does not require that the combination include all of A, B, C, D, E, and F (although it may include all of A, B, C, D, E, and F). More precisely, it indicates that it may include any combination of two or more of A, B, C, D, E, and F. In other words, it is equivalent to the phrase "one or more elements selected from the group consisting of A, B, C, D, E, and F, and any combination of two or more of A, B, C, D, E, and F."

[0162] Similarly, the term "its salt" also refers to "its various salts". Therefore, when this disclosure refers to "elements selected from the group consisting of A, B, C, D, E, F, their salts and combinations thereof", it means that it may include one or more of A, B, C, D and F, may include one or more of the salts of A, B, C, D, E and F, or may include any combination of any two of the salts of A, B, C, D, E, F, the salts of A, B, C, D, E and F.

[0163] Salts mentioned throughout this disclosure may include salts with counterions such as alkali metal, alkaline earth metal, or ammonium counterions. However, this list of counterions is not limiting.

[0164] Some of the compounds discussed throughout this disclosure may be in the composition as salts, or may be added to the composition as salts (and dissociate in the composition). Therefore, all compounds and amounts refer to both the salt form and the dissociated form of the compound. In other words, even if the statement "its salt" is not specifically or explicitly directed at a component that can form a salt or is available as a salt, it should be understood to include the salt form of the compound.

[0165] The term "inclusive" in the description of a concentration range means that the limit of the range is included within the defined interval.

[0166] Except as provided in the Operating Examples or where otherwise stated, all figures indicating the amount of an ingredient and / or reaction conditions shall be understood to be modified in all cases by the term “about”, meaning within + / - 5% of the figures shown.

[0167] The term "INCI" is an abbreviation for International Nomenclature of Cosmetic Ingredients, which is a naming system for describing personal care ingredients provided by the International Nomenclature Committee of the Personal Care Products Council.

[0168] All components and elements expressly set forth in this disclosure may be excluded negatively from the claims. In other words, the compositions of this disclosure may be free of or substantially free of all components and elements expressly recited throughout this disclosure.

[0169] Some of the different categories of components identified may overlap. In cases where overlap is possible and the composition contains two components (or more than two overlapping components), the overlapping components or ingredients do not represent more than one component. For example, if a polyacrylate falls within the description of both a thickening polymer and a film-forming polymer, the polyacrylate specifically referred to should be understood as either a thickening polymer or a film-forming polymer only. For example, when a claim simultaneously refers to both a thickening polymer and a film-forming polymer (even if a polyacrylate can function as both a thickening polymer and a film-forming polymer), the specific polyacrylate cannot be simultaneously understood as both a thickening polymer and a film-forming polymer. In other words, a single compound or ingredient cannot simultaneously be used as two different components of the claimed composition.

[0170] All publications and patent applications cited in this specification are incorporated herein by reference, and for any and all purposes, as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. In the event of any inconsistency between this disclosure and any publication or patent application incorporated herein by reference, this disclosure shall prevail.

[0218] These quantities are described as weight percentages based on the total weight of the composition.

[0219] Test 1 - In vitro test for limiting and controlling volume and frizz on hair samples - with and without pigment. physical agents

[0220] The rinse-off hair cosmetic compositions of Examples 1 and 2 of the present invention are compared with prior art conditioning compositions comprising water, cetearyl alcohol, dimethicone, glycerin, behenyltrimethylammonium chloride, fragrance, quaternium-33, lactic acid, hydroxycitronellal, phenoxyethanol, behenyltrimethylammonium methyl sulfate, limonene, benzyl salicylate, linalool, benzyl alcohol, amodimethicone, isopropanol, 2-oleamido-1,3-octadecanediol, cetyltrimethylammonium chloride, citronellol, cetyl alcohol, coumarin, hexylcinnamaldehyde, and pentylcinnamaldehyde.

[0221] The compositions of Examples 1 and 2, as well as the compositions of the prior art, were applied to raw curly hair samples (three 2.7 g samples for each composition) after the step of contacting the hair with shampoo, and were evaluated according to a curliness limitation score (from 0 to 10) at 24 hours after hair treatment (T24), at 24 hours but after breaking the stiffness effect (finger-through-the-hair test (TAT), and after combing the TAT sample (TAP)). Limitation measurements were performed using imaging data. Results are shown in... Figure 1 .

[0222] In addition, the compositions of Examples 1 and 2, as well as the compositions of the prior art, were applied to raw curly hair samples (three 2.7-gram samples for each composition) after the step of contacting the hair with the shampoo, and evaluated based on volume and frizz control. Measurement data were generated by a trained panel of experts and scored from 1 to 4 in increments of 0.5, where 4 represents the highest score (optimal value).

[0223] In particular, Figure 1 The data indicate that when the commercially available conditioning agent is replaced with Composition Example 1, the limiting exhibits similar performance. However, when a purple pigment (Composition Example 2) is added, the limiting shows a trend toward superior limiting (T24) and persistence limiting (TAT and TAP).

[0224] Test 2 - In vitro test for limitation, volume and frizz control on hair samples - hair mask

[0225] The wash-off hair cosmetic composition according to Example 1 of the present invention is compared with a prior art hair mask composition comprising water, cetearyl alcohol, dimethyl silicone oil, glycerin, behenyltrimethylammonium chloride, fragrance, lactic acid, hydroxycitronellol, sodium hydroxide, hydroxypropyltrimonium hydrolyzed wheat protein, hydrolyzed rice protein, phenoxyethanol, arginine, limonene, benzyl salicylate, linalool, benzyl alcohol, pentyl glycol, aminodimethyl silicone oil, isopropanol, 2-oleamido-1,3-octadecanediol, serine, cetyltrimethylammonium chloride, citronellol, coumarin, hexylcinnamaldehyde, and pentylcinnamaldehyde.

[0226] The compositions of Example 1 and those of the prior art were applied to raw curly hair samples (three 2.7 g samples of each composition) after the step of contacting hair with shampoo and conditioner, and evaluated according to a curliness limitation score (from 0 to 10) at 24 hours after hair treatment (T24), at 24 hours but after breaking the stiffness effect (finger-through-the-hair (TAT) and after combing the TAT sample (TAP)). Limitation measurements were performed using imaging data. For multiple time intervals between application to and removal from the hair, including no time interval between application to and removal of the composition (0 min.), 1 minute between application to and removal of the composition (1 min.), 3 minutes between application to and removal of the composition (3 min.), and 5 minutes between application to and removal of the composition (5 min.), the results are shown in Figure 2 A.

[0227] In addition, the compositions of Example 1, along with existing techniques, were applied to raw curly hair samples (three 2.7-gram samples of each composition) after the step of contacting the hair with shampoo and conditioner, and evaluated based on volume and frizz control. Measurement data were generated by a trained panel of experts and scored from 1 to 4 in increments of 0.5, where 4 represents the highest score (optimal value). The results are shown in... Figure 2 B.

[0228] like Figure 2As shown in A and 2B, compared to a reference hair mask with a 5-minute interval between application and removal of the composition, the rinse-out hair care composition of Example 1 of the present invention, used as a hair mask, exhibits excellent results in terms of volume and frizz control at any time (0, 1, 3, or 5 min) between application and removal of the composition. In terms of performance limitation, when used as a hair mask without a time interval (rinsing immediately after application), the composition of Example 1 of the present invention already has comparable performance to the reference hair mask with a 5-minute interval between application and removal of the composition. Furthermore, when the time interval between application and removal of the composition is longer (1, 3, or 5 min), the composition of Example 1 of the present invention shows even better performance limitation.

[0229] Test 3 - In vitro testing of hair sample limits, volume, and frizz control - Pigment-containing hair masks

[0230] The wash-off hair cosmetic composition of Example 2 of the present invention is compared with a prior art hair mask composition comprising water, cetearyl alcohol, dimethyl silicone oil, glycerin, behenyltrimethylammonium chloride, fragrance, lactic acid, hydroxycitronellol, sodium hydroxide, hydroxypropyltrimethylammonium chloride hydrolyzed wheat protein, hydrolyzed rice protein, phenoxyethanol, arginine, limonene, benzyl salicylate, linalool, benzyl alcohol, pentyl glycol, aminodimethyl silicone oil, isopropanol, 2-oleamido-1,3-octadecanediol, serine, cetyltrimethylammonium chloride, citronellol, coumarin, hexylcinnamaldehyde, and pentylcinnamaldehyde.

[0231] The compositions of Example 2 and those of the prior art were applied to raw curly hair samples (three 2.7 g samples of each composition) after the step of contacting hair with shampoo and conditioner, and evaluated according to a curliness limitation score (from 0 to 10) at 24 hours after hair treatment (T24), at 24 hours but after breaking the stiffness effect (finger-through-the-hair (TAT) and after combing the TAT samples (TAP)). Limitation measurements were performed using imaging data. For multiple time intervals between application to and removal from the hair, including no time interval between application to and removal of the composition (0 min.), 1 minute between application to and removal of the composition (1 min.), 3 minutes between application to and removal of the composition (3 min.), and 5 minutes between application to and removal of the composition (5 min.), the results are shown in Figure 3 A.

[0232] The compositions of Example 2, along with existing techniques, were applied to raw curly hair samples (three 2.7 g samples of each composition) after the step of contacting the hair with the shampoo and conditioner, and evaluated based on volume and frizz control. Measurements were generated by a trained panel of experts and scored from 1 to 4 in increments of 0.5, where 4 represents the highest score (optimal value). Results are shown in... Figure 3 B.

[0233] Data shows that the composition of Example 2, when applied to and removed from the hair within 3 minutes, has comparable results in terms of immediate duration (T24) to the standard care procedure (where 5 minutes are between application and removal), but is lacking in terms of duration (TAT and TAP). Figure 3 A). In terms of volume and fuzz control ( Figure 3 B) shows superior results at all times between the application of the composition to and removal from the hair.
