Abstract: The present invention relates to compositions containing hydrolytically stable multi-purpose polymers that are polymerized from a monomer mixture comprising: at least one amino-substituted meth(acrylate) (ASMA) monomer or salt thereof; and at least one nonionic vinyl (NIV) monomer, wherein the monomer mixture optionally comprises one or more of at least one vinyl associative (VA) monomer; at least one vinyl surfactant (VS) monomer; and/or at least one polymerizable silicone macromer (PSM) and wherein the monomer mixture further optionally comprises one or more of at least one crosslinking (XL) monomer; at least one chain transfer agent (CTA); and/or at least one polymeric stabilizer. The multi-purpose polymers of the present invention can also be prepared from monomer mixtures containing chain transfer agents or other functional components commonly utilized in polymerization processes.

Abstract: The present invention relates to surfactant-polymer blends that are useful as thickeners for a variety of personal care products. In one embodiment, the surfactant-polymer blends of the present invention comprises: (a) at least one anionic surfactant; (b) at least one amphoteric or zwitterionic surfactant; and (c) at least one hydrophobically-modified polymer formed from a mixture comprising: (i) an ?,?-ethylenically unsatured carboxylic acid monomer; (ii) a nonionic, co-polymerizable ?,?-ethylenically unsaturated monomer; and (iii) an ethylenically unsaturated hydrophobically-modified associative monomer. The surfactant-polymer blends of the present invention are useful as thickeners in a variety of products including, but not limited to, personal care products, health care products, household care products, institutional and industrial care products, and industrial applications.

Abstract: The present invention relates to antiperspirant compositions comprising a cationic hydrophobically modified polymeric gelling agent and an acidic antiperspirant compound. The antiperspirant compositions are transparent, phase stable, non-whitening and non-staining to the skin and clothing following topical application. The present invention also is directed to methods of using the antiperspirant compositions.
