Description

Title of the invention: Keratinous material care composition technical field

[0001] The present invention relates to a cosmetic composition and its use. In particular, the present invention relates to a keratinous material care composition. The present invention also relates to a non-therapeutic process for the care of keratinous materials. STATE OF THE ART

[0002] Today, more and more young people suffer from hair loss, which is generally triggered by stress, an unhealthy lifestyle, and emotional disturbances. Cortisol, an emotional hormone induced by stress, is one of the underlying causes of hair loss. A systemic and local increase in cortisol, followed by follicular inflammation and damage, can ultimately lead to hair loss.

[0003] Usually, a product claiming an anti-hair loss action produces its benefits mainly by providing lubrication / smooth texture to the hair, easy detangling or by using certain active ingredients for regulating the hair growth cycle.

[0004] However, many commercially available anti-hair loss products are not effective in reducing hair loss.

[0005] In addition, some anti-hair loss products are not satisfactory in terms of scalp sensation such as scalp soothing.

[0006] In addition, it is often desired that hair treatment and / or scalp care products have a fresh aqueous texture for pleasant use, leaving no filler / residue and achieving a lasting clean / non-greasy scalp condition.

[0007] Thus, there is always a need for a composition, in particular for the care of keratinous materials, which can deliver soothing relief to the scalp and reduce hair loss, while having a fresh aqueous texture for pleasant use. Summary of the invention

[0008] Thus, an object of the present invention is to propose a composition, preferably a keratinous material care composition, which can deliver scalp soothing and reduce hair loss, while having a fresh aqueous texture for pleasant use.

[0009] Another object of the present invention is to propose a non-therapeutic process for the care of keratinous materials.

[0010] According to the first aspect, the present invention proposes a composition, preferably for the care of keratinous materials, comprising: a. at least one extract of tephrosia purpurea seed; b. niacinamide and / or its derivatives; c. at least one thickener; and d. at least one volatile organic solvent.

[0011] The inventors have discovered that with the combination of components a)-d) defined above, the composition according to the present invention has a fresh aqueous texture and can result in good revitalization of the hair and scalp.

[0012] In addition, the composition according to the present invention can reduce hair loss and deliver a good scalp sensation in terms of scalp soothing.

[0013] According to the second aspect, the present invention proposes a non-therapeutic process for the care of keratinous materials, comprising the application of the composition according to the present invention on the keratinous materials.

[0102] Soothing the scalp and resistance to hair loss

[0103] The scalp soothing and resistance to hair loss after the period of use delivered by each composition of inventive examples 1-3 and comparative examples 1-2 were evaluated according to the following consumer test protocols: 1. Recruitment of 30 young women (subjects), aged 22 to 35, who had themselves declared a hair loss problem; 2. division of the young women into 5 groups (6 subjects / group); 3. instruction given to subjects to use each composition of inventive examples 1-3 and comparative examples 1-2 every day at home for two weeks, the instruction for use being the following protocol:

[0104] - washing hair using a shampoo they normally use;

[0106] - application of 12 g of the composition to the entire head of hair and scalp hairy;

[0107] - massage for 2 minutes;

[0108] - blowing on the hair to dry it completely; 1. After a 2-week usage period, feedback from subjects was collected via a questionnaire based on their user experience during the trial period, with the following questions:

[0109] - I can perceive less hair loss than before;

[0110] - My scalp is more soothed than before.

[0111] The answers to the questions were given according to the following scoring standard, and the scores for each composition were averaged.

[0112] 5 means very likely.

[0113] 4 means probable.

[0114] 3 means no difference.

[0115] 2 means unlikely.

[0116] 1 means very unlikely.

[0117] The average scores on scalp sensation and resistance to hair loss of inventive examples 1-3 and comparative examples 1-2 have been summarized in Table 5.
