A personal care composition comprising a silicone resin of the generic formula: MQ, wherein the ratio of M to Q is about from 0.01/1 to about 3.96/1; MDT, wherein x is about 0.01 to about 3,900,000, y is about 0.035 to about 10,000,000, z is about 0.35 to about 8,000,000; TD, wherein the ratio of T to D is about 0.001/1 to about 73/1; or a combination comprising at least one of the foregoing resins, wherein the resin or resin combination is present in an amount effective to increase the SPF of the formulation at least about 10% over the same formulation without the resin or resin combination. The silicone resins are easily formulated, provide a unique non-tacky sensory experience and exhibit advantageous spreadability while permitting the introduction of additional functional benefits such as homogeneity, better organic compatibility, reduced skin irritation and improved skin feel or shine.

Personal care compositions with enhanced properties, method of manufacture, and method of use thereof

The cross-linked hydrosilylation reaction product of an alkenyl functional silicone compound, a silylhydride functional silicone compound, and one or more allyl started, hydrogen, alkyl, aryl or acyl terminated polyether compounds exhibits stability, compatibility with polar organic solvents and is useful as a component in personal care compositions.

Polar solvent compatible polyethersiloxane elastomers

The cross-linked hydrosilylation reaction product of an alkenyl functional silicone compound, a silylhydride functional silicone compound; and one or more &agr;,&bgr;-unsaturated alkenes exhibits hydrolytic stability, compatibility with organic solvents and is useful as a component in personal care compositions.

Silicone elastomer

A silicone emulsion useful as a component in hair care compositions In a first aspect of the present invention, a silicone emulsion comprises the product of a base catalyzed reaction of an aqueous emulsion of a hydroxy end-stopped polyorganosiloxane and an aminofunctional silane according to the structural formula: ##STR1## wherein: R.sup.1 and R.sup.2 are each independently H, alkyl, or an aminoalkyl group according to the structural formula: ##STR2## and wherein: R.sup.4, R.sup.5 and R.sup.6 are each independently (C.sub.1 -C.sub.12)alkyl or (C.sub.2 -C.sub.8)alkoxy, provided that at least two of R.sup.4, R.sup.5 and R.sup.6 are each (C.sub.2 -C.sub.8)alkoxy;

Aminofunctional silicone emulsion

A non-aqueous silicone emulsion containing a silicone phase and an organic phase is useful as a component in various personal care compositions. The silicone phase contains a crosslinked silicone elastomer and a low molecular weight silicone fluid and the organic phase contains an organic liquid.

Non-aqueous silicone emulsions

A method of imparting internal mold release properties to reaction injection molding polyurethane compositions by the addition of a perfluoroalkylorganocarboxylic acid or a salt thereof. This invention also relates to the production of novel perfluoroalkylorganodibutyltindioxide compounds which are inherently catalytic and can also impart the property of internal mold releasability to RIM compositions.
