The present disclosures are directed to compositions comprising a polymer having branched silicone substituted by at least one alkylcarboxy group in a free or salt form and cross-linked with an alkyl functional cross-linker, which has the benefits of compatibility with hydrophilic ingredients and particulates in personal care components and the resultant personal care applications.

Carboxylic acid functional cross-linked silicone compositions

The present disclosures are directed to compositions comprising a polymer having linear or branched silicone substituted by at least one alkylcarboxy group and cross-linked with an alkyl functional cross-linker, which has the benefits of compatibility and structuring of personal care components and the resultant personal care applications.

Ester modified cross-linked silicone compositions

A heterogeneous catalyst comprising a metal-containing polymer matrix covalently bonded to a support material and a method of making and using such catalysts. The metal-containing polymer matrix comprises metal nano-particles encapsulated in a polymer matrix, e.g., a siloxane. In one aspect, the metal-containing polymer matrix can be bonded to the support material via a hydrophobic group attached to the support material. The catalyst can be recovered after being used in a metal catalyzed reaction and exhibit excellent catalytic activity upon reuse in subsequent reactions.

Personal care composition comprising silicone network

The present invention provides curable compositions that are free of metal catalysts including both tin and non-tin metal catalysts. The curable compositions employ a catalyst comprising curable polymers having reactive terminal silyl groups. In particular, a silylated carboxylic acid is an alternative to organotin or other metal catalysts. In addition, the catalyst may be used with an amino-containing adhesion promoter or a mixture of amine-containing adhesion promoters and an amino-containing siloxane. The combination of these materials accelerates the condensation curing of moisture curable silicones/non-silicones even in the absence of a metal-based catalyst.
