Description

Title of the invention: CLEANSING AND / OR MAKE-UP REMOVAL COMPOSITION FOR KERATINOUS MATERIALS technical field

[0001] The present invention relates to a composition, preferably for cleansing and / or removing makeup from keratinous materials. The present invention also relates to a non-therapeutic process for cleansing and / or removing makeup from keratinous materials using said composition. STATE OF THE ART

[0002] Cleansing the skin or removing makeup is very important for skin care. In particular, it is very important for makeup users to have an effective makeup remover available. It must be as effective as possible because oily residues, such as dirt, excess sebum, remnants of daily cosmetics, and makeup products, especially waterproof ones, accumulate in skin folds, can clog pores, and lead to the appearance of blemishes.

[0003] Several types of skin cleansing or makeup-removing products are known, for example, biphasic makeup removers, cleansing water, creams and lotions.

[0004] The two-phase makeup remover is effective but impractical to use, as it needs to be shaken before each use and the two phases are consumed at different rates. Cleansing water and micellar lotion leave a feeling of freshness, but are impractical because they can run due to their low viscosity.

[0005] Makeup is essentially composed of a hydrophobic substance for a long-lasting makeup effect. It is difficult to remove makeup using a hydrophilic composition. Therefore, it is necessary for a makeup remover to contain hydrophobic substances as solvents, such as vegetable oils, hydrocarbon oils, fatty esters, fatty alcohols, and silicone oils.

[0006] However, if the makeup remover contains a higher quantity of oil, the makeup remover is difficult to stabilize, because due to aging or a change in temperature, the oil droplets cannot be retained, and then collapse until they leak.

[0007] Thus, there is a need to formulate a stable composition to remove makeup from keratinous materials. Summary of the invention

[0008] The inventors have discovered that such a need can be satisfied by the present invention.

[0009] Thus, according to one aspect, the present invention relates to a composition, preferably for cleaning and / or removing makeup from keratinous materials, comprising: i. at least one glycolipid; ii. at least one alkyl sulfosuccinate; and iii. at least 10% by weight of at least one oil, relative to the total weight of the composition.

[0010] The composition according to the present invention is stable.

[0011] According to another aspect, the present invention proposes a non-therapeutic process for cleaning and / or removing makeup from keratinous materials, in particular from the skin, comprising applying the composition according to the present invention to the keratinous materials, in particular to the skin, and rinsing off said composition after an optional period of time.

[0012] Other subjects and features, aspects and advantages of the present invention will be presented in the following description and, in part, will become obvious from the description or can be learned through practice of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0013] Unless otherwise defined, all technical and scientific terms used in this document have the same meaning as that commonly understood by a person skilled in the art in the field covered by the present invention. Where the definition of a term in this description conflicts with the meaning commonly understood by a person skilled in the art in the field covered by the present invention, the definition described herein shall apply.

[0014] In what follows and unless otherwise indicated, the limits of a range of values ​​are included in that range, in particular in the expressions "between...and..." and "from...to...".

[0015] For the purposes of the present invention, the term "keratinous material" is understood to refer to the covering of human skin and mucous membranes such as the lips. Facial skin is particularly considered in the context of the present invention.

[0016] Moreover, the expression "at least one" used in this description is equivalent to the expression "one or more".

[0017] Throughout this application, the term "including" shall be interpreted as encompassing all the features specifically mentioned as well as optional, additional, unspecified features. As used herein, the use of the term "including" also discloses the embodiment in which no no particularity other than the specifically mentioned particularities is present (i.e., "consisting of").

[0018] In the present invention, all percentages refer, unless otherwise specified, to a percentage by weight.

[0019] According to one aspect, the composition of the present invention comprises: i. at least one glycolipid; ii. at least one alkyl sulfosuccinate; and iii. at least 10% by weight of at least one oil, relative to the total weight of the composition. Glycolipids

[0020] The composition according to the present invention comprises at least one glycolipid.

[0021] The term "glycolipid" means a compound formed from a lipid to which one or more sugar compounds are attached.

[0022] The inventors discovered that glycolipids can act as mild surfactants, to care for the skin and deliver a non-drying, smooth finish. They also act as a foam enhancer.

[0023] Preferably, the glycolipid is chosen from rhamnolipids, glucolipids, sophorolipids, trehalolipids, cellobiose lipids, and mixtures thereof.

[0024] More preferably, the glycolipid is chosen from rhamnolipids, glucolipids, trehalolipids and their mixtures.

[0025] Even more preferably, glycolipid is chosen from among rhamnolipids. Glucolipids:

[0026] The (a) glycolipids may be glucolipids, which contain a glucose fraction and may be represented by the general formula (I): p

[0029] - p denotes an integer from 1 to 4, and

[0030] - q denotes an integer from 4 to 10, preferably equal to 6.

[0031] Glycolipids can be produced by the bacterium Alcaligenes sp. MM1.

[0032] Suitable fermentation processes are reviewed by Mr. Schmidt in his doctoral thesis (1990), Technical University of Braunschweig, and by Schulz and al. (1991) Z. Naturforsch., 46C, 197-203. The glucolipids are recovered from the fermentation broth by solvent extraction using diethyl ether or a dichloromethane:methanol or chloroform:methanol mixture. Sophorolipids

[0033] Glycolipids can be sophorolipids, which contain a sophorose fraction and can be represented by the general formula (II):

[0034] in which:

[0035] - R3 and R4 individually represent a hydrogen atom or an acetyl group,

[0036] - R5 represents a saturated or unsaturated hydrocarbon group, hydroxylated or not hydroxylated, comprising from 1 to 9 carbon atoms, preferably a methyl group,

[0037] - R6 represents a saturated or unsaturated hydrocarbon group, hydroxylated or not hydroxylated, having from 1 to 19 carbon atoms,

[0038] provided that the total number of carbon atoms in groups R5 and R6 does not exceed 20 and is preferably from 14 to 18.

[0039] Sophorolipids can be incorporated into the composition according to the present invention either in the form of an open-chain free acid, where R7 represents a hydrogen atom and R8 represents a hydroxy group OH, or in its lactone form, where a lactone ring is formed between R7 and R8, as indicated by formula (III): (HD

[0040] in which:

[0041] - R3, R4, R5 and R6 are as defined above,

[0042] provided that at least one of R3 and R4 represents an acetyl group.

[0043] Sophorolipids can be produced by yeast cells, for example, Torulopsis apicola and Torulopsis bombicola cells. The fermentation process generally uses sugars and alkanes as substrates.

[0044] Suitable fermentation processes are reviewed in AP Tulloch, JFT Spencer and PAJ Gorin, Can. J. Chem. (1962), 40, 1326, and U. Gobbert, S. Lang and F. Wagner, Biotechnology Letters (1984), 6 (4), 225. The resulting product is a mixture of various open-chain sophorolipids and sophorolipid lactones which can be used in mixtures, or the required form can be isolated.

[0045] It is possible to use as a sophorolipid, for example the product sold under the name Sopholiance S by Givaudan and the product sold under the name BioToLife by BASF. Trehalolipids

[0046] Glycolipids can be trehalolipids, which contain a trehalose fragment and can be represented by the general formula (IV): ! ! i * « COOH

[0049] Trehalolipids can be produced by bacterial fermentation using the marine bacterium Arthrobacter sp. Ek 1 or the freshwater bacterium Rhodococcus erythropolis. Suitable fermentation processes are proposed by Ishigami et al. (1987), J. Jpn. Oil Chem. Soc., 36, 847-851, Schultz et al. (1991), Z. Naturforsch., 46C, 197-203, and Passeri et al. (1991), Z. Naturforsch., 46C, 204-209. Cellobiose lipids

[0050] Glycolipids can be cellobiose lipids, which contain a cellobiose fragment and can be represented by the general formula (V):
