Description

Title of the invention: KERATINOUS MATERIAL CARE COMPOSITION AND MASK COMPRISING IT technical field

Furthermore, the present invention relates to a non-therapeutic method for the treatment of keratinous materials. STATE OF THE ART

[0002] The development of cosmetic products is ongoing. Preservatives are essential in cosmetic products to inhibit microbiology. The main types of microbiological contamination are molds and bacteria. Current mask preservatives are primarily based on SymSave H (4'-hydroxyacetophenone) technology. SymSave H (4'-hydroxyacetophenone) is a good, very mild antioxidant that has proven to be a good inhibitor of Aspergillus niger (mold), but weak against Enterococcus faecalis (bacteria).

[0003] It is desired that the 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] Furthermore, the formulation of environmentally friendly cosmetic products, which are designed and developed taking environmental issues into account, is becoming a major objective in an effort to meet 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 principles that are environmentally friendly, in particular of natural origin, more specifically bio-based and / or from sustainable non-petrochemical sources, and / or biodegradable and / or obtained by extraction processes requiring low energy and water consumption in order to offer compositions that reduce the environmental impact of products. Summary of the invention

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

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

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

[0011] Thus, according to a first aspect, the present invention proposes a composition, preferably for the care of 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 among the 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 proposes a mask, preferably intended for the treatment of keratinous materials, comprising:

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

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

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

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

Accordingly, unless otherwise stated, the numerical values ​​and parameters described herein are approximate values ​​that may be changed according to the desired performance as required.

[0025] As used herein, the expression "at least one" used in this description is equivalent to the expression "one or more".

[0026] For the purposes of the present invention, the term "keratinous material" refers to covering the skin. Facial skin and the skin around the eyes are particularly considered in the context of the present invention.

[0027] The composition according to the present invention comprises: 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 among the beta-hydroxy acids and their derivatives. Sphingomonas ferment extract

[0028] According to the first aspect, the composition of the present invention comprises at least 0.01% by weight of Sphingomonas ferment extract, relative to the total weight of the composition.

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

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

[0031] Bacteria of the genus Sphingomonas are generally cultured in a suitable medium and grown at 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, can be carried out, such as freeze-drying, dehydration, filtration, purification, freezing possibly followed by thawing, sterilization, column chromatography, grinding, etc.

[0032] Preferably, the bacterial extract is a bacterial lysate comprising, in particular, the compounds contained within the bacterium, and therefore present in the bacterial pellet of the bacterial culture after centrifugation. Preferably, the bacterial extract is a bacterial lysate comprising the intracellular medium and / or the constituent elements of the cell walls and / or membranes.

[0033] A lysate commonly refers to a substance obtained at the end of the destruction or dissolution of biological cells by a phenomenon called cell lysis, thus causing the release of intracellular biological constituents naturally contained in the cells of the microorganism in question.

[0034] For the purposes of the present invention, the term lysate is used interchangeably to designate the entire lysate obtained by lysis of the microorganism concerned or only a fraction thereof.

[0035] The lysate used is therefore formed in whole or in part from intracellular biological constituents and from constituents of cell walls and membranes.

[0036] This cell lysis can be achieved using different technologies, such as osmotic shock, thermal shock such as freezing followed optionally by thawing, ultrasound, or under mechanical stress such as centrifugation, for example.
