Abstract
Abstract A method for producing solid gel antiperspirant sticks at a lower processing temperature, said sticks containing an acidic antiperspirant metal active compound, dibenzyl monosorbitol acetal as the gelling agent and at least one alcohol, a solvent which is an organic compatible, small organic compound of not greater than about five carbon atoms and is a good hydrogen bond donor or acceptor, and a stabilizing compound which is a basic metallic salt, and the gelled antiperspirant sticks formed by the process.
