Clear antiperspirant stick gelled with dibenzylidene sorbitol and containing a guanidine compound as gel stabilizer, and the process of making same

摘要

Disclosed is a clear, antiperspirant material-containing, gel stick composition, containing an acidic antiperspirant material (e.g., an aluminum salt) and gelled with dibenzylidene sorbitol, the composition including a guanidine compound (for example, guanidine carbonate or aminoguanidine bicarbonate) as a stabilizing agent to reduce degradation of the gel and of the dibenzylidene sorbitol gelling agent. Also disclosed are continuous processes for forming the gel stick composition, wherein degradation of the dibenzylidene sorbitol gelling agent in the presence of the antiperspirant material is reduced.
