Description

Title of the invention: KERATINOUS MATERIAL CARE COMPOSITION technical field

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

[0002] Consumers worldwide are seeking new cosmetic products to improve the appearance of keratinous materials and in particular of the skin, especially by providing the skin with an optical cosmetic effect, such as softness and a good glow.

[0003] Cosmetic products that can bring the above-mentioned optical effects to the skin are known, for example, anti-aging water in the cosmetics industry, which is a technological permeation system combined with a gentle exfoliating motor to meet consumer needs in terms of radiance and softness.

[0004] However, some products for giving the skin radiance and softness are still not satisfactory. For example, some products are not stable.

[0005] It is desirable that such cosmetic compositions be stable.

[0006] Thus, there is always a need to formulate a care composition for keratinous materials, particularly of the skin, which can provide keratinous materials, particularly of the skin, with radiance and softness and which is stable. Summary of the invention

[0007] The present invention aims to develop a care composition for keratinous materials, in particular skin, which can provide keratinous materials, in particular skin, with radiance and softness and which is stable.

[0008] The present invention also aims to propose a non-therapeutic method for treating keratinous materials, particularly skin, with the above compositions.

[0009] The inventors have now discovered that it is possible to formulate a care composition for keratinous materials, particularly of the skin, which can provide keratinous materials, in particular of the skin, with radiance and softness and which is stable.

[0010] Consequently, in a first aspect, the present invention proposes a composition, preferably for the care of keratinous materials, comprising:

[0011] (i) at least one first surfactant selected from poly- fatty acid esters glycerol, polyoxyalkylated fatty acid esters of polyol and one of their combinations; and

[0012] (ii) at least 0.4% by weight of at least one second surfactant with an HLB >10, which is different from the first surfactant, relative to the total weight of the composition; and

[0013] (iii) at least one polyhydroxy acid.

[0014] The inventors have discovered that the composition according to the present invention can be used to care for keratinous materials, in particular to give them shine and softness.

[0015] The inventors have further discovered that the composition according to the present invention is stable.

[0016] In certain embodiments, the composition according to the present invention is transparent.

[0017] As used here, the term "transparent" means that the turbidity of the composition is less than 10 NTU.

[0018] In a second aspect, the present invention proposes a non-therapeutic method for the treatment of keratinous materials, comprising the application of the composition according to the first aspect of the present invention to the keratinous materials.
