Abstract

An invention is disclosed which comprises gelling agents which (1) contain both siloxane groups and hydrogen-bonding groups to thicken compositions containing silicone fluids (volatile and/or non-volatile silicone fluids); (2) are non-flowable solids at room temperature; and (3) dissolve in a fluid which contains silicone at a temperature of 25-250 degrees C to form a translucent or clear solution at a temperature in this range. Cosmetic compositions may be made by adding at least one active ingredient such as an antiperspirant.
