Description

The present invention relates to a foaming cleaning composition in the form of an aqueous gel comprising at least one anionic surfactant chosen from acyl (C1-C4) alkyl isethionates and at least one anionic surfactant chosen from alkyl sulphoacetates, and also use of said composition, especially in the cosmetics field, as cleaning or makeup removal products for keratin materials such as the skin, keratin fibers (eyelashes and hair), the scalp, as well as for treating oily skin and / or disinfecting the skin; skin and / or scalp. The cleaning of the skin is very important for the care of the face. It must be as efficient as possible because fatty residues such as excess sebum, the remains of cosmetics used daily and makeup products accumulate in skin folds and can clog the pores of the skin and lead to appearance of buttons. One way to clean the skin properly is to use foaming cleansers. Foaming cleansers currently available commercially are in the form of loaves, gels or foaming creams. They generally contain either soaps which have the advantage of giving a creamy foam but may cause tightness due to their excessive detergency, or foaming surfactants such as sulphated surfactants, in particular sodium lauryl sulfate (SLS) or sodium laureth sulfate (SLES), or amphoteric surfactants such as coco betaine, cocoamidopropyl betaine or sodium cocoamphodiacétate, which are very efficient in terms of foam and detergency but which are called into question, rightly or wrongly, for their ecotoxic or eco-harmful environmental profile. Since the formulation of environmentally friendly cosmetics is an important issue to satisfy a new expectation of consumers, especially that of eco-designed and / or natural products, it is necessary to propose foaming compositions without sulphated surfactant or surfactant. amphoteric active, having good cosmetic qualities, mainly viscosity and foam. Furthermore, the foaming products can be thickened with a salt, for example sodium chloride, for certain surfactants, or by adding an alkyl-PEG type thickener such as PEG-150 distearate. or PEG-55 propylene glycol oleate, or by the addition of a natural gum type gelling agent, in particular xanthan gum, scleroglucan gum or carrageenan gum. Salt thickening is a known and widely used approach for surfactant systems containing sulfates and amphoters, since it allows both to be cheap and also not to alter the qualities of foam; but in general, it does not significantly thicken systems without sulfate and / or without amphoter. On the other hand, the increase in the viscosity of the medium by another thickening or gelling agent is more versatile but often has a negative impact on the foam qualities of the formula (starting, amount of foam).

Foaming compositions without sulphate or amphoteric surfactants having a good viscosity obtained intrinsically or by adding salt, and good foam qualities should therefore be available. It has surprisingly been found that the combination of an anionic surfactant chosen from acyl (C1-C4) alkyl isethionates and an anionic surfactant chosen from alkyl sulphoacetates makes it possible to obtain clear compositions of appearance. gel, stable over time. The subject of the present invention is therefore a foaming cleaning composition in the form of an aqueous gel comprising at least one anionic surfactant chosen from acyl (C1-C4) alkyl isethionates and at least one anionic surfactant chosen from alkyl sulphoacetates. The composition according to the invention makes it possible to obtain a clear foaming gel having a good level of viscosity and good cosmetic qualities, mainly of foam (starting, quality, quantity), even with a level of sulphated surfactants and weak amphoteric surfactants. or when the composition is free of such surfactants. In addition, the addition of a salt in this type of composition, for example NaCl, leads to a significant increase in viscosity. Moreover, the composition is stable over time. The composition according to the invention being intended for topical application, it contains a physiologically acceptable medium, that is to say compatible with the skin, the mucous membranes, the hair and the scalp.
