In addition, the present invention relates to a non-therapeutic method for caring for keratinous materials. STATE OF THE ART

[0002] The development of cosmetic products is continuous. Preservatives are essential in cosmetic products to inhibit microbiology. The main types of contamination induced by microbiology are molds and bacteria. Current mask preservatives are mainly based on SymSave H (4'-hydroxyacetophenone) technology. SymSave H (4'-hydroxyacetophenone) is a good, very mild antioxidant agent, which has been shown to be a good inhibitor for Aspergillus Niger (mold), but weak for Enterococcus faecalis (bacteria).

[0003] It is desired that cosmetic products be effective in inhibiting Enterococcus faecalis.

[0004] There is a need to develop cosmetic compositions that are effective in inhibiting Enterococcus faecalis.

[0005] Moreover, the formulation of environmentally friendly cosmetic products, which are designed and developed with environmental issues in mind, is becoming a major objective in an effort to address global challenges.

[0006] It is therefore essential to propose more sustainable compositions to address these environmental concerns.

[0007] In this context, it is important to develop new ingredients and / or active ingredients that are environmentally friendly, in particular of natural origin, more specifically bio-sourced and / or derived from sustainable non-petrochemical sources, and / or biodegradable and / or obtained by extraction processes requiring low energy and water consumption in order to provide compositions that reduce the environmental impact of the products. Summary of the invention

[0008] An object of the present invention is to provide cosmetic compositions which are effective in inhibiting Enterococcus faecalis.

[0009] Another object of the present invention is to provide a mask which comprises said cosmetic composition.

[0010] Yet another object of the present invention is to provide a non-therapeutic method for caring for keratinous materials.

[0011] Thus, according to a first aspect, the present invention provides a composition, preferably for caring for keratinous materials, comprising: i. at least 0.01% by weight of sphingomonas ferment extract, relative to the total weight of the composition; ii. at least one hydroxylated carboxylate; and iii. at least one compound A chosen from beta-hydroxy acids and their derivatives.

[0012] The composition according to the present invention can effectively inhibit Enterococcus faecalis.

[0013] The composition according to the present invention is suitable for a mask, in particular those intended for the care of keratinous materials.

[0014] According to a second aspect, the present invention provides a mask, preferably intended for the care of keratinous materials, comprising:

[0015] A) a cotton fabric for a mask, and

[0016] B) the composition according to the present invention on the wadding fabric for mask.

[0017] The composition and the mask according to the present invention can be used for the care of keratinous materials.

[0018] According to a third aspect, the present invention provides a non-therapeutic method for caring for keratinous materials, comprising the application of the composition or mask according to the present invention to the keratinous materials.

[0029] Sphingomonas ferment extract is the extract of the product obtained by the fermentation of Sphingomonas. It is known to contain glycosphingolipids (GSL) such as seramide, dihydrosphingosine and glucuronic acid, and is valued for its reduction of lipid peroxidation and the functioning of key biomarkers of senescence, thus preventing skin aging.

[0030] The extracts according to the invention can be prepared by any conventional method well known to those skilled in the art. These methods generally comprise a fermentation, isolation, separation and purification step.

[0031] The bacterium of the genus Sphingomonas is generally cultured in a suitable medium and grown to a desired density. Preferably, the bacteria themselves are concentrated by any known method, such as centrifugation. The concentrated bacteria can then be used directly as a crude preparation, or additional processing steps, well known to those skilled in the art, may be carried out, such as lyophilization, dehydration, filtration, purification, freezing possibly followed by thawing, sterilization, column chromatography, grinding, etc.
