Title: Elastomeric silicone containing an active ingredient

Abstract: Elastomeric silicones, especially elastomeric silicone polyethers, are prepared by combining and reacting (A) an .tbd.Si--H containing polysiloxane, (B) a mono-alkenyl polyether, (C) an active ingredient such as a vitamin, antimicrobial agent, sunburn prevention agent, astringent, or sex hormone, (D) an .alpha.,.omega.-unsaturated hydrocarbon, (E) a platinum catalyst, and (F) an oil. The reaction of components (A)-(F) is allowed to continue, forming a crosslinked three-dimensional gelled network of the elastomeric silicone polyether containing the active ingredient and the oil. The compositions are useful in personal and health care applications, personal hygiene, and household cleaning applications.
