Abstract
Silicone compositions that are functionalized with 1,2 or 1,3 glycol bearing substituents render antiperspirant salts soluble, partially soluble therein or partially miscible therewith. Such functionalized silicones in conjunction with antiperspirant salts produce clear antiperspirant gel sticks.
