Description

Title of the invention: CLEANSING AND / OR CARE COMPOSITION FOR KERATINOUS MATERIALS technical field

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

[0002] Hair loss in young people is a common problem that is usually triggered by stress, unhealthy lifestyle habits, and emotional disturbances. One of the main biochemical markers associated with stress-induced hair loss is cortisol, a hormone that can be activated by emotional stress. Elevated cortisol levels can lead to systemic and localized increases in the scalp, which in turn can cause follicular inflammation and further damage to hair follicles, ultimately resulting in hair loss.

[0003] Furthermore, the washing and rinsing stage is a critical time for observing hair loss. Intense friction, rubbing, and massaging during washing easily cause significant hair loss from the root and breakage of the hair fibers. In particular, when consumers comb their hair or run their fingers through it during rinsing, they readily notice numerous hair fibers left on the comb or their fingers.

[0004] Conventional hair and scalp treatments are typically designed to target hair fibers, providing a smooth texture and ease of detangling using cationic polymers. Excessive coating deposits on the fibers due to these conditioning polymers easily lead to flat hair and an oily scalp, along with scalp irritation and discomfort.

[0005] Some anti-hair loss products are not satisfactory in terms of soothing the scalp.

[0006] Thus, there is a need for products for the cleansing and / or care of keratinous materials, such as hair and / or scalp, which can deliver a good volumized appearance to the hair, soothe the scalp, reduce hair loss, while improving the smooth texture and detangling of the hair. Summary of the invention

[0007] An object of the present invention is therefore to develop compositions for the cleaning and / or care of keratinous materials, which can deliver a good volumized appearance to the hair, soothe the scalp, reduce hair loss, while improving the smooth texture and detangling of the hair.

[0008] Thus, according to a first aspect, the present invention relates to a composition, preferably for cleaning and / or caring for keratinous materials, comprising: a. at least one extract of tephrosia purpurea seed; b. at least one anionic surfactant of the sulfate type; and c. niacinamide and / or one of its derivatives.

[0009] According to a second aspect, the present invention relates to a non-therapeutic process for cleaning and / or caring for keratinous materials, comprising the application of the composition according to the present invention to the keratinous materials.

[0010] The inventors have discovered that the composition according to the present invention can improve the smooth texture and detangling of hair, and effectively combat hair loss.

[0011] The inventors also discovered that the composition according to the present invention can deliver a good volumized appearance to the hair and soothe the scalp.

[0012] The inventors have further discovered that the composition according to the present invention exhibits good foaming performance.
