Abstract
Disclosed are single-phase antiperspirant compositions and corresponding methods of application, wherein the compositions are single-phase systems that comprise a solubilized antiperspirant active, a volatile silicone and selected coupling materials that are substantially free of Si—OH and Si—H functional groups and that have a solubility parameter of from about 7 to about 12, wherein the sum total solubility parameter of the essential components in the composition is m about 9 to about 13. These compositions provide improved low residue performance, enhanced stability, improved efficacy, and/or improved cosmetics.
