Description

Title of the invention: RINSE-IN HAIR COSMETIC COMPOSITION, Hair treatment method, Method for delivering lasting definition to curly hair AND Use of a COMPOSITION FIELD OF INVENTION

[0001] The present invention relates to rinse-out cosmetic hair compositions comprising (a) at least one organic acid; (b) a non-aqueous solvent comprising at least one compound with 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) at least one ester; (f) at least one surfactant selected from cationic, nonionic, anionic, and amphoteric surfactants and mixtures thereof; and (g) water. The invention also relates to a method for treating hair, particularly curly hair, a method for delivering lasting definition to curly hair, and the use of the rinse-out cosmetic hair composition. CONTEXT OF THE INVENTION

[0002] People use various cosmetic and personal care compositions to enhance the appearance and feel of keratinous fibers, such as hair.

[0003] Particularly with regard to curly hair, consumers are always faced with problems related to curl definition such as frizz, volume, and shape. Curly hair tends to frizz and increase significantly in volume when exposed to high humidity, chemical treatments, and other factors. Furthermore, the shape and definition of curls are lost after sleeping.

[0004] Numerous attempts have been made to develop products intended to discipline, define and control hair, especially curly hair, by strengthening / maintaining curl definition, curl retention and curl regularity, without giving the hair an unnatural and stiff feel and / or appearance, but these products have resulted in additional problems or maintenance difficulties.

[0005] In this sense, there is a need on the market for curly hair products that define curls in a lasting way, since the standard routine for curly hair includes the use of several cosmetic products along the entire length of the hair and must be reset every three days, as curls tend to lose definition and a fresh appearance after this period – it is a very time-consuming, which means that consumers repeat all the steps approximately every other day, including washing their hair and applying different cosmetic products.

[0006] Therefore, it is desirable to have a hair cosmetic product for curly hair which not only helps to define curls, but also offers lasting cosmetic benefits to the consumer's hair, such as resistance to frizz, which leaves hair shiny and is easy to apply.

[0007] The inventors of the present invention have obtained, in a surprising and unexpected manner, hair cosmetic compositions, specially designed for curly hair, comprising (a) at least one organic acid, (b) a non-aqueous solvent comprising at least one compound with 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) at least one ester; (f) at least one surfactant selected from cationic, non-ionic, anionic and amphoteric surfactants, and mixtures thereof; and (g) water, which are capable of penetrating the hair fiber without accumulation on the surface of the fiber (creating new bonds that make the hair stronger for longer), while also providing lasting curl definition and also delivering cosmetic benefits, such as shine, a smooth feel, and spreadability. Summary of the invention

[0008] The present invention relates to rinse-off hair cosmetic compositions comprising (a) at least one organic acid; (b) a non-aqueous solvent comprising at least one compound with 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) at least one ester; (f) at least one surfactant selected from cationic, nonionic, anionic, and amphoteric surfactants and mixtures thereof; and (g) water. The invention also relates to a method for treating hair, particularly curly hair, and a method for delivering lasting definition to curly hair. Brief description of the drawings

[0171] The pH of the formulation examples of the invention ranged from about 4 to about 7. It was also found that the presence of esters in the formulation examples of the invention and / or vegetable waxes improved the spreading ability of the formulas during application of the formulations to the hair. IN VITRO TESTS AND RESULTS Test methodology

[0172] The technology of the present invention delivers long-lasting, frizz-free definition because its active ingredients penetrate the hair shaft, creating new bonds that make the hair more resistant to daily stress for longer. Thus, the inventors have achieved superior definition and frizz control compared to standard shampoos on the market, since the active ingredients can penetrate the hair shaft quickly.

[0173] When the shampoo has silicone, the performance on these attributes is improved in terms of volume and frizz control due to the greater deposition of active ingredients on the surface of the hair, while the basic ingredients of the technology penetrate.

[0174] The conditions of the present test are as follows: • all the formulas of the present invention have been applied in the form of a rinse-off shampoo; • The definition measurement was made using imaging data. The higher the value The higher the number, the better the result; • The measurement data for volume and frizz control were generated by a trained panel. The score ranges from 1 to 4 in increments of 0.5, where 4 is the highest score (best value); • In the context of Definition, the data includes the following subheadings: • T24 means that the data was taken 24 hours after the application; • TAT means that the data was taken in the same wick as T24, but after being touched to break the rigid effect; • TAP means that the TAT wick is combined and a measurement is taken.

[0175] Test 1 - In vitro tests of volume and frizz definition and control on hair strands - Shampoo with silicone and pearlescent agent

[0176] The inventive formula of Ex. C is inferior to the inventive formula of Ex. A in terms of the definition of the immediate loops (T24). With regard to the durable definition (TAT and TAP), there is a tendency towards the superiority of the inventive formula of Ex. A.

[0177] The difference between the formulas of Ex. A and Ex. C is the addition of the basic ingredients of the technology in Ex. C, which allows for an improvement in the definition as a whole.

[0178] The two formulas of Inventive Ex. A and Inventive Ex. C were also compared to Ex. 1. This comparison shows that the formulation of Inventive Ex. A is applied as a rinse-off product and has similar performance to the shampoo composition of Ex. C in frizz control and lasting definition (TAT and TAP) while maintaining superiority in immediate definition (T24).

[0179] Therefore, the formulation of the inventive Ex. A as a rinse-off product presents improved results, in addition to its active ingredients themselves, since the formulation of the inventive Ex. A shows a tendency towards superiority when used as a rinse-off product used as a shampoo.

[0180] These results can be verified in Figures IA and IB.

[0181] Test 2 - In vitro tests of volume and frizz definition and control on hair strands - Shampoo with silicone without pearlescent agent

[0182] When silicone is added to the standard composition of Ex. 2, the immediate definition (T24) and the durable definition (TAP) are similar to the formula of inventive Ex. A.

[0183] On the other hand, when the basic ingredients of Inventive Ex. A were added to the composition of Ex. D, the results obtained were similar to those of Inventive Ex. A, and superior in terms of durable definition TAP as a formula of Ex. A.

[0184] These results can be verified in Figures 2A and 2B.

[0200] The formula of inventive Ex. A applied as a rinse-off product used as shampoo had superior results in controlling volume and frizz compared to the Ex. 6 formula, which does not contain the active ingredients of the Ex. A formula.

[0201] By comparing the formula of inventive Ex. H, identical to Ex. 6 but with the basic active ingredients of the formula of Ex. A, it is possible to demonstrate the improvement in volume and frizz control results compared to Ex. 6.

[0202] These results can be verified in Figures 6A and 6B.

[0203] Test 7 - In vitro tests for defining and controlling volume & frizz on Hair extensions - Shampoo with pigment

[0204] With regard to the pigmented product used as shampoo, the inventive formula of Ex. B obtained the best results in curl definition on T24, TAT and TAP.

[0205] For volume and frizz, the inventive formula of Ex. B had superiority in volume control compared to the shampoo composition without the active ingredients of the technology, such as Ex. 7. However, when key ingredients of the inventive formula of Ex. B are added to the shampoo composition of Ex. I, an improvement in volume and frizz control is obtained.

[0206] These results can be verified in Figures 7A and 7B.
