  • an anhydrous cosmetic composition comprising alkylcellulose, at least one branched dextrin ester and at least one fatty alcohol.
  • cosmetic compositions must provide an aesthetic effect when applied to the skin and/or lips, and maintain this aesthetic effect over time. Once applied, they must in particular resist various external factors capable of modifying their aesthetic effect such as perspiration or tears for foundation, or saliva for lipstick.

  • ethylcellulose makes it possible, when it is used in a sufficient amount in cosmetic and/or therapeutic compositions, to obtain deposits having improved adhesion and stability properties, in particular on the lips or skin. It has also been demonstrated that ethylcellulose, solubilized in a sufficient amount in the compositions, enables the formation of a film on the skin and/or lips to be facilitated, and the water resistance of this film to be improved.
  • mono-alcohols having 2 to 8 carbon atoms are preferred for solubilizing sufficient amounts of ethylcellulose in cosmetic or pharmaceutical compositions.
  • these volatile mono-alcohols have the disadvantage of being potentially uncomfortable (tautness, dryness), or even irritating for the skin and/or lips, and consequently may be detrimental when used repeatedly on the skin or lips.
