Abstract
Anhydrous antiperspirant composition in aerosol form comprising an antiperspirant active agent and a water-insoluble film-forming block ethylenic polymer The present invention relates to an anhydrous composition in aerosol form containing: i) an oily phase comprising, in a physiologically acceptable medium: —at least one volatile oil, and —one or more antiperspirant active agents chosen from aluminum and/or zirconium salts, and —one or more water-insoluble film-forming block ethylenic polymers comprising a first block with a glass transition temperature (Tg) of greater than or equal to 85° C. and a second block with a Tg of less than or equal to 20° C., and ii) one or more propellants; the said oily phase containing less than 15% by weight and even more preferably less than 12% by weight of non-volatile polydimethylsiloxane relative to the total weight of the oils. The invention also relates to a cosmetic process for treating human perspiration, to a use of the same and to an aerosol device using the said cosmetic composition.
