The present invention relates to an anhydrous foaming composition comprising anionic and nonionic surfactants and at least 25% of fillers and/or fibres, and to the use thereof for cleansing and/or removing makeup from keratinous substances.
Foaming compositions in the liquid form require the use of a gelling or thickening agent, such as, for example, gums, in order to exhibit a satisfactory consistency. However, these gums may exhibit the disadvantage of inhibiting the development of the foam.
For these reasons, it may be advantageous to provide foaming products in the solid form which do not comprise water or which comprise very little water and which, in addition, exhibit the advantage of preventing microbiological problems and thus of not requiring the use of preservatives.
For example, the document FR 2 779 684 teaches solid compositions in the form of a deformable paste based on specific pulverulent fillers and anionic surfactants. These compositions can only be obtained using an extruder, which can be restrictive in processing terms.
Furthermore, for some years, the cosmetic market has been marked by a very high demand for formulations comprising ingredients of natural origin. Consumers desire formulations devoid of chemicals, to which they prefer ingredients of natural origin which are renowned for their better tolerance and affinity with the skin and which are more environmentally friendly.
A search is thus underway to obtain foaming cleansing products comprising compounds of natural origin which are satisfactorily harmless with regard to keratinous substances, which exhibit good microbiological preservation, and which are easily and pleasant to use while nevertheless having the properties required for foaming products, namely good mixing with water, rapid transformation into foam and good rinsing.
“Natural compound” is understood to mean a compound which is obtained directly from the earth or soil or from plants or animals via, if appropriate, one or more physical processes such as, for example, a grinding, a refining, a distillation, a purification or a filtration.
Compounds “of natural origin” is understood to mean a natural compound which has been subjected to one or more additional chemical or industrial treatments, bringing about modifications which do not affect the essential qualities of this compound, and/or a compound predominantly comprising natural constituents which have or have not been subjected to transformations, as indicated above.
Mention may be made, as nonlimiting example of additional chemical and industrial treatment bringing about modifications which do not affect the essential qualities of a natural compound, of those allowed by the controlling bodies, such as Ecocert (Reference system for biological and ecological cosmetic products, January 2003), or defined in recognized handbooks in the field, such as Cosmetics and Toiletries Magazine, 2005, Vol. 120, 9:10.
The Applicant Company has discovered that an anhydrous composition comprising a specific combination of anionic and nonionic surfactants and a high content of fillers makes it possible to achieve these objectives.
More specifically, a subject-matter of the invention is an anhydrous cosmetic composition comprising, in a physiologically acceptable medium:
The compositions according to the invention, after contributing water, exhibit good initiation of foam and a smooth and copious form.
“Anhydrous” composition is understood to mean a composition comprising less than 0.5% of water, preferably entirely devoid of water.
Another subject-matter of the invention is a method for cleansing or removing makeup from keratinous substances, such as the skin, including the scalp, keratinous fibres, such as the eyelashes or hair, and/or lips, characterized in that a cosmetic composition as defined above is applied to the said keratinous substances.
The composition according to the invention is intended for topical application and thus comprises a physiologically acceptable medium. “Physiologically acceptable medium” is understood here to mean a medium compatible with keratinous substances, such as the skin, mucous membranes, scalp, eyes and/or keratinous fibres, such as the eyelashes or hair.
Nonionic Surfactants
The nonionic surfactants can be chosen, for example, from phospholipids, alkyl polyglucosides (APG), maltose esters, sucrose esters, hydrophobicized gums, polyglycerolated fatty alcohols, esters of glycerol and of a fatty acid, oxyalkylenated glycerol esters, oxyalkylenated sugar esters, polyethylene glycol fatty acid esters, esters of a fatty acid and of sorbitan, glucamine derivatives, such as 2-ethylhexyloxycarbonyl-N-methylglucamine, and their mixtures. The phospholipids used in the composition according to the invention can be of vegetable or animal origin and can be provided in the pure form or in the form of a mixture.
The phospholipids used in the composition can in particular be lecithins, which are a complex mixture of phosphatides mainly chosen from phosphatidic acid, phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, lysophosphatidylcholine and/or phosphatidylinositol, in combination with variable amounts of other substances, such as triglycerides, glycolipids, sphingolipids, fatty acids and carbohydrates.
It will thus be possible to choose either the phospholipids mentioned above or the lecithins comprising these phospholipids.
According to a specific embodiment of the invention, the phospholipid or phospholipids are chosen from nonhydrogenated lecithins and hydrogenated lecithins.
Nonhydrogenated lecithins are generally obtained by lipid extraction, using nonpolar solvents, from vegetable or animal fatty substances. This lipid fraction usually comprises, predominantly, glycerophospholipids, including phosphatidylcholine.
The animal or vegetable sources which can be used to extract the nonhydrogenated lecithins are, for example, soya, sunflower or eggs. The glycerophospholipids included, in high proportion, in these lecithins are mainly phosphatidylcholine and phosphatidylethanolamine.
The nonhydrogenated lecithins suitable for the implementation of the present invention can be lecithins resulting from soya, sunflower, eggs and/or their mixtures.
The lecithins are normally supplied in the form dissolved in fatty acids, triglycerides or other solvents or in the form of powders or cakes.
These are usually mixtures of lecithins, the glycerophospholipid content of which, in the products as sold, generally vary from approximately at least 15% to approximately at least 95%.
Mention may be made, among the nonhydrogenated lecithins which may be suitable for the implementation of the cosmetic compositions in accordance with the present invention, of lecithins sold under the references Nattermann Phospholipid®, Phospholipon 80® and Phosale 75® by American Lecithin Company, Epikuron 145V, Topcithin 300, Emulmetik 930, Ovothin 200 and Organic Lecithin, which are sold by Lucas Meyer.

According to one embodiment, the composition according to the invention comprises fibres which can make it possible to improve the disintegration of the composition, the initiation of foam and the quality of the foam.
“Fibre” should be understood as meaning an object with a length L with a diameter D such that L is greater than D and preferably much greater than D, D being the diameter of the circle in which the cross section of the fibre appears. In particular, the ratio L/D (or aspect ratio) is chosen in the range extending from 3.5 to 2500, preferably from 5 to 500, and better still from 5 to 150.
The fibres which can be used in the composition of the invention can be fibres of synthetic or natural and inorganic or organic origin, and they can be flexible or stiff. They can be short or long, individual or organized, for example braided. They can have any shape and can in particular have a circular or polygonal (square, hexagonal or octagonal) cross section, according to the specific application envisaged. In particular, their ends are blunted and/or smoothed in order to avoid inflicting injury.
In particular, the fibres have a length ranging from 1 μm to 10 mm, preferably from 0.1 mm to 5 mm and better still from 0.1 mm to 3 mm. They have a cross section included within a circle with a diameter ranging from 2 nm to 500 μm, preferably ranging from 100 nm to 100 μm. The weight of the fibres is often given in denier or decitex.
