Description

Technical Field

[0001] The present invention relates to a rinse-off hair cosmetic composition comprising (a) at least one organic acid, (b) a non-aqueous solvent containing at least one compound having at least one hydroxyl group, (c) at least one amino acid, (d) at least one fatty compound selected from vegetable oils, vegetable resins, vegetable waxes, and mixtures thereof, (e) water, and (f) at least one surfactant selected from cationic surfactants, nonionic surfactants, and mixtures thereof. The present invention also relates to a method of treating hair, particularly curly hair, a method of providing improved curl definition to hair, and the use of a composition for producing a rinse-off hair care product that provides improved curl definition.

Background Art

[0002] Several cosmetic personal care compositions are used to enhance the appearance and feel of keratin fibers such as hair.

[0003] Particularly with respect to curly hair, consumers are constantly dealing with problems related to curl definition, such as shrinkage, volume, and shape. Curly hair tends to shrink and become very voluminous, especially under high humidity conditions and when exposed to chemical treatments. In addition, the shape and definition of the curls are lost after sleep.

[0004] Many attempts have been made to develop products that enhance / maintain curl definition, curl hold, and curl regularity to condition, clarify, and control hair, particularly curly hair, without making the feel and / or appearance of the hair unnatural and stiff, but such products have either caused further problems or been difficult to maintain.

[0005] For example, high-tech products typically require a large amount of product to achieve good combability and hair feel. However, considering that the effects of such products do not last long, consumers have to reapply the product several times a day or after sleep to regain crispness and frizz control. Since such products do not penetrate the keratin fibers but remain on the surface of the hair fibers, the product accumulates on the surface of the hair, resulting in a heavy feeling, a wet appearance, an unnatural texture, and a greasy sensation.

[0006] In this sense, there is a market need for a curly hair product that sharpens curls in a way that makes them last longer, without the need to reapply the product between washes or after sleep, and with reduced need to use large amounts of the product between washes.

[0007] In addition, a standard daily routine for curly hair involves the use of several cosmetic products throughout the entire length of the hair, and must be reset every two days, because curls tend to lose their definition and fresh appearance after such a period. This is a very time-consuming daily routine that involves consumers restarting all steps, including washing the hair and applying various cosmetic products, approximately every two days. [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] Therefore, it is desirable to have a rinse-off hair cosmetic for curly hair that not only helps to define curls but also provides consumers with long-lasting cosmetic benefits to their hair, such as resistance to frizz, makes hair shiny, is easy to apply, does not leave hair feeling wet or heavy, and is improved by the use of such a product. There is also a need for a rinse-off hair cosmetic for curly hair that allows consumers to reduce the amount of product they use and extend the effect of the composition, thereby giving them extra days before they have to resume their daily routine for curly hair makeup. [Means for solving the problem]

[0009] The inventors of the present invention have, surprisingly and unexpectedly, realized a rinse-off hair cosmetic composition, particularly 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 vegetable oils, vegetable resins, vegetable waxes, and mixtures thereof, (e) water, and (f) at least one surfactant selected from cationic surfactants, nonionic surfactants, and mixtures thereof, which penetrates the hair fibers without accumulating on the surface of the fibers, while not only providing curl clarity, long-lasting curl clarity, frizz control, a natural look, and desired volume until the next wash, but also providing cosmetic benefits such as not looking heavy on the hair, shine, smooth texture, and spreadability.

[0010] The present invention relates to a rinse-off 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 vegetable oils, vegetable resins, vegetable waxes, and mixtures thereof, (e) water, and (f) at least one surfactant selected from cationic surfactants, nonionic surfactants, and mixtures thereof.

[0156] The quantity should be expressed as a mass percentage of the total mass of the composition.

[0157] Test 1 - In Vitro Test of Clarity and Volume & Frizz Control on Hair Swatches - Conditioners with and without Pigment The rinse-off hair cosmetic compositions according to Examples 1 and 2 of the present invention were compared with a state-of-the-art conditioner composition containing water, cetearyl alcohol, dimethicone, glycerin, behentrimonium chloride, fragrance, quaternium-33, lactic acid, hydroxycitronellal, phenoxyethanol, behentrimonium methosulfate, limonene, benzyl salicylate, linalool, benzyl alcohol, amodimethicone, isopropyl alcohol, 2-oleamide-1,3-octadecanediol, cetrimonium chloride, citronellol, cetyl alcohol, coumarin, and hexyl cinnamal and amyl cinnamal.

[0158] After the process of contacting the hair with shampoo, compositions Ex.1 and Ex.2, as well as a composition of the technical level, were applied to virgin curly hair swatches (three swatches of 2.7 grams each of composition). The curl clarity was evaluated according to a score (0-10) at 24 hours after treatment (T24), 24 hours after breaking the stiffness effect (by running fingers through the hair (TAT)), and after combing the TAT swatch (TAP). Clarity was measured using image data. The results are shown in Figure 1.

[0159] In addition, after the process of contacting the hair with shampoo, compositions Ex.1 and Ex.2, as well as a standard-of-technical composition, were applied to virgin curly hair swatches (three swatches of 2.7 grams each of composition) and evaluated according to volume and curl control. A trained panel generated the measurement data, and the scores ranged from 1 to 4 in increments of 0.5, with 4 being the highest score (best value).

[0160] In particular, the data in Figure 1 shows that when a commercially available conditioner is replaced with composition Ex.1, the clarity performance is similar. However, in the case of composition Ex.2, which contains purple pigment, the clarity tends to be superior in terms of clarity (T24) and long-lasting clarity (TAT and TAP).

[0161] Test 2 - In Vitro Test of Clarity and Volume & Curl Control for Hair Swatches - Mask The rinse-off hair cosmetic composition according to Example 1 of the present invention was compared with a state-of-the-art mask composition containing water, cetearyl alcohol, dimethicone, glycerin, behentrimonium chloride, fragrance, lactic acid, hydroxycitronellal, sodium hydroxide, hydroxypropyltrimonium hydrolyzed wheat protein, hydrolyzed rice protein, phenoxyethanol, arginine, limonene, benzyl salicylate, linalool, benzyl alcohol, pentylene glycol, amodimethicone, isopropyl alcohol, 2-oleamide-1,3-octadecanediol, serine, cetrimonium chloride, citronellol, coumarin, hexyl cinnamal, and amyl cinnamal.

[0162] After the process of contacting the hair with shampoo and conditioner, the composition of Ex.1 and the composition of the State of the Art were applied to virgin curly hair swatches (3 swatches of 2.7 grams per composition), and evaluated according to a score (0-10) of curl clarity at 24 hours after treatment (T24), 24 hours after breaking the stiffening effect (fingers run through the hair (TAT)), and after combing the TAT swatch (TAP). Clarity was measured using image data. The results for several time intervals between application and removal of the composition from the hair, including no time interval (0 min), 1 minute interval (1 min), 3 minutes interval (3 min), and 5 minutes interval (5 min), are shown in Figure 2A.

[0163] In addition, after the process of contacting the hair with shampoo and conditioner, the composition of Ex.1 and the State of the Art composition were applied to virgin curly hair swatches (three swatches of 2.7 grams each of the composition) and evaluated according to volume and curl control. A trained panel generated the measurement data, and the scores ranged from 1 to 4 in increments of 0.5, with 4 being the highest score (best value). The results are shown in Figure 2B.

[0164] As shown in Figures 2A and 2B, the rinse-off hair care composition of Ex.1 of the present invention, used as a mask, shows superior results in volume and frizz control compared to a reference mask with a 5-minute interval between application and removal of the composition from the hair, regardless of the time interval (0, 1, 3, or 5 minutes) between application and removal of the composition from the hair. In terms of clarity performance, when used as a mask with no waiting time (application followed by rinsing), the composition of Ex.1 of the present invention already exhibits the same clarity as a reference mask with a 5-minute interval between application and removal of the composition from the hair. Furthermore, when the time interval between application and removal of the composition from the hair is longer (1, 3, or 5 minutes), the composition of Ex.1 of the present invention shows superior clarity.

[0165] Test 3 - In Vitro Test of Clarity and Volume & Curl Control on Hair Swatches - Mask with Pigment The rinse-off hair cosmetic composition according to Example 2 of the present invention was compared with a state-of-the-art mask composition containing water, cetearyl alcohol, dimethicone, glycerin, behentrimonium chloride, fragrance, lactic acid, hydroxycitronellal, sodium hydroxide, hydroxypropyltrimonium hydrolyzed wheat protein, hydrolyzed rice protein, phenoxyethanol, arginine, limonene, benzyl salicylate, linalool, benzyl alcohol, pentylene glycol, amodimethicone, isopropyl alcohol, 2-oleamide-1,3-octadecanediol, serine, cetrimonium chloride, citronellol, coumarin, hexyl cinnamal, and amyl cinnamal.

[0166] After the process of contacting the hair with shampoo and conditioner, the composition of Ex.2 and the composition of the State of the Art were applied to virgin curly hair swatches (3 swatches of 2.7 grams per composition), and evaluated according to a score (0-10) of curl clarity at 24 hours after treatment (T24), 24 hours after the stiffening effect was broken (fingers were run through the hair (TAT)), and after the TAT swatch was combed (TAP). Clarity was measured using image data. The results for several time intervals between application and removal of the composition from the hair, including no time (0 min), 1 minute between application and removal of the composition from the hair (1 min), 3 minutes between application and removal of the composition from the hair (3 min), and 5 minutes between application and removal of the composition from the hair (5 min), are shown in Figure 3A.

[0167] In addition, after the process of contacting the hair with shampoo and conditioner, the composition of Ex.2 and the State of the Art composition were applied to virgin curly hair swatches (three swatches of 2.7 grams each of the composition) and evaluated according to volume and curl control. A trained panel generated the measurement data, and the scores ranged from 1 to 4 in increments of 0.5, with 4 being the highest score (best value). The results are shown in Figure 3B.

[0168] The data show that composition Ex.2, applied to hair for 3 minutes between application and removal, yields the same immediate clarity (T24) as the standard daily procedure with a 5-minute application and removal time, but loses long-lasting clarity (TAT and TAP) (Figure 3A). For volume and frizz control (Figure 3B), all time intervals between application and removal of the composition show superiority.
