Abstract: Segregation of antiperspirant actives suspended in anhydrous compositions employing ester oils or non-volatile silicone oils having a refractive index of at least 1.5, preferably together with an alcohol oil, gelled with a fibre-forming amide gellant can be inhibited by including a segregation inhibitor, especially an arylene-alkylene block copolymer, such as a tri-block copolymer e.g. a styrene/ethylenebutylene/styrene copolymer or a styrene/butylene copolymer.

Abstract: An antiperspirant composition comprising an aqueous phase, an antiperspirant salt and a polymer having Bronsted acid groups, characterised in that the antiperspirant salt and polymer are suspended in the aqueous phase and the composition has a Sauter mean particle size (D[3,2]) of 30 microns or less.
