Abstract
Gel compositions containing a silicone elastomer from the reaction of an organohydrogensiloxane having at least two SiH containing cyclosiloxane rings in its molecule, a compound having at least two aliphatic unsaturated hydrocarbon groups in its molecule, and a hydrosilylation catalyst. The silicone elastomer reaction product may itself be a gelled composition, or optionally may be contained in a carrier fluid to form a gel. The gel compositions may further contain a personal or healthcare active. The actives may be incorporated into the gel via either a pre or post load method.
