ABSTRACT:
Cosmetic composition packaged under pressure in an aerosol device, in the presence of a propellant, characterized in that it contains, in a cosmetically acceptable aqueous medium, at least one quaternary cellulose ether corresponding to the formula: ##STR1## Rcellulose is a radical of an anhydroglucose unit. in which at least one of the groups R.sub.1, R.sub.2 or R.sub.3 denotes a radical of formula ##STR2## in which m is an integer with a value from 2 to 10, R.sub.4, R.sub.5 and R.sub.6 denote a lower alkyl radical containing 1 to 4 carbon atoms, X.sup..crclbar. denotes a cosmetically acceptable anion, the remaining groups R.sub.1, R.sub.2 or R.sub.3 denoting a lower hydroxyalkyl radical containing 1 to 4 carbon atoms, and at least one graft copolymer of vinyl acetate, crotonic acid and polyalkylene glycol, under conditions such that they form, from the device, a stable and firm foam on expansion in air.
