Antiperspirant aerosol compositions having reduced residue build-up

An antiperspirant cosmetic agent comprises: (a) 2.5 to 15 wt. % of at least aluminium salt of formula (I) Ala(OH)bClc (I), where is from 1 to 4; b is from 1 to 4.9 and c is from 1.5 to 3. Preferably, a is 2, b is 4.5 and c is 1.5. The cosmetic agent also comprises 5.0 to 25 wt.% of at least one non-volatile ester; (c) at least one volatile silicone compound; and (d) at least one propellant, where the weight ratio of the at least one non-volatile ester (b) to the at least one volatile silicone compound (c) in the agent is 10:1 to 1:1.5. Preferably the non-volatile ester is selected from C12 to C15 alkyl benzoate, phenoxyethyl caprylate, ethylhexyl palmitate, isopropyl myristate, and their mixtures. The volatile silicone compound may be cyclopentasiloxane. The cosmetic agent may also contain bentonite, and preferably comprises no alkoxylated, in particular ethoxylated, silicones.
