This invention relates to silicone elastomer compositions in the form of gels and/or organized structures. The silicone elastomer compositions are produced by reacting a siloxane having a first reactive group with a crosslinker having a second reactive group in a diluent. One reactive group is selected from epoxy-functional groups or chlorohydrin functional groups while the other reactive group is a functional group that reacts with epoxy-functional groups or chlorohydrin functional groups (i.e. amine, hydroxyl). The silicone elastomer compositions of the instant invention are particularly useful in personal care products, textiles, auto care products, and laundry products and for the delivery of active ingredients.

This invention pertains to silicone core-shell or gel particles that contain active ingredients. The silicone particles are produced by emulsifying and reacting a composition comprising a siloxane have a first reactive group, a crosslinker having a second reactive group, at least one emulsion liquid, a surfactant and an active ingredient. The active ingredient is encapsulated in the silicone particle and are useful in personal care products, textiles, auto care products, and laundry products for the delivery of active ingredients.
