Abstract
(EN)
Composition comprising a saturated fatty alcohol, at least one fatty-chain anionic surfactant, a polyol and at least one silicone oil The present invention relates to a composition, preferably a cosmetic composition, in the form of an oil-in-water emulsion, in which an oily phase is dispersed in an aqueous phase, comprising: (a) from 2.5% to 7% by weight, relative to the total weight of the composition, of at least one saturated C16-C22 and preferably C16-C18 fatty alcohol; (b) at least one anionic surfactant including at least one C16-C22 and preferably C16-C18 hydrocarbon-based chain; (c) at least one polyol; (d) at least 60% by weight, relative to the total weight of the oily phase, of at least one silicone oil; the fatty alcohols (a)/anionic surfactants (b) mass ratio being between 10:1 and 6:4. The composition according to the invention has the advantage of having a very soft, non- tacky texture which is fresh on application, and is thus very pleasant touse and easy to apply. Moreover, the composition is stable, and is notably macroscopically and microscopically stable after two months of storage under temperature conditions ranging from 4°C to 45°C.

La présente invention concerne une composition, de préférence une composition cosmétique, sous la forme d'une émulsion huile-dans-eau, dans laquelle une phase huileuse est dispersée dans une phase aqueuse, comprenant : (a) de 2,5 à 7 % en poids, par rapport au poids total de la composition, d'au moins un alcool gras saturé en C16-C22 et de préférence en C16-C18; (b) au moins un tensioactif anionique comprenant au moins une chaîne hydrocarbonée en C16-C22 et de préférence en C16-C18; (c) au moins un polyol; (d) au moins 60 % en poids, par rapport au poids total de la phase huileuse, d'au moins une huile de silicone; le rapport massique des alcools gras (a)/tensioactifs anioniques (b) étant compris entre 10:1 et 6:4. La composition selon l'invention présente l'avantage d'avoir une texture très molle, non collante qui est fraîche lors de l'application, et est donc très agréable à utiliser et facile à appliquer. De plus, la composition est stable, et est notamment stable macroscopiquement et microscopiquement après deux mois de stockage dans des conditions de température allant de 4 °C à 45° C.
