COMPOSITION COMPRISING A C-GLYCOSIDE DERIVATIVE OR A CUCURBIC ACID DERIVATIVE, A PASTY FATTY BODY AND A NON-IONIC DERIVATIVE OF MODIFIED HYDROPHOBIC CELLULOSE
The subject of the present invention is a cosmetic composition in the form of an emulsion comprising at least one active agent chosen from C-glucoside derivatives, in particular C-beta-D-xylopyranoside-2-hydroxy-propane, and acid derivatives. cucurbic, such as the sodium salt of 3-hydroxy-2-pentylcyclopentyl) acetic acid, at least one pasty fatty substance, and at least one nonionic derivative of cellulose comprising one or more hydrophobic substituents having from 8 to 30 atoms of carbon. The present invention makes it possible to obtain emulsions containing active agents chosen from C-glucoside derivatives and cucurbic acid derivatives which are stable, even without the use of an emulsifying surfactant or with a low level of emulsifying surfactant (for example lower than at 3%), and which provide good sensory pleasure, even when the composition has a high rate of these assets. The composition according to the invention provides an excellent sensoriality, without rough effect neither greasy nor sticky and without effects of pellucts. In addition, it enhances the perception of effectiveness through immediate effects felt from the application of the product: nutritional effects, soothing, moisturizing. La présente invention a pour objet une composition cosmétique sous forme d'émulsion comprenant au moins un actif choisi parmi les dérivés C-glucoside, en particulier le C-béta-D -xylopyranoside-2-hydroxy-propane, et les dérivés d'acide cucurbique, tels que le sel de sodium de l'acide 3-hydroxy-2-pentylcyclopentyl)acétique, au moins un corps gras pâteux, et au moins un dérivé non ionique de cellulose comprenant un ou plusieurs substituants hydrophobes ayant de 8 à 30 atomes de carbone. La présente invention permet d'obtenir des émulsions contenant des actifs choisis parmi les dérivés C-glucoside et les dérivés d'acide cucurbique qui sont stables, même sans l'utilisation de tensioactif émulsionnant ou avec un faible taux de tensioactif émulsionnant (par
