The properties of 2-pyrrolidone-4-carboxylic substituted polysiloxanes can be dramatically altered by increasing the presence of the carboxylic-substituted pyrrolidone monomer of the polysiloxane, such that the amidopolysiloxane has an acid equivalent weight of about 3:00-3,000 daltons and a molecular weight average Mw of about 1,000-60,000 daltons resulting in enhanced detergent and water solubilities and the ability to form water-in-oil emulsions thereby providing usefulness across a broad range of formulations having enhanced electrolytic and silicone and/or hydrocarbon compatibility and cleansing properties.

Les propriétés des polysiloxanes 2-pyrrolidone-4-carboxyliques substitués peuvent être grandement modifiées en augmentant la présence du monomère de pyrrolidone carboxylique substitué du polysiloxane, de sorte que l~amidopolysiloxane a un poids d~équivalent acide d~environ 3:00-3 000 daltons et un poids moléculaire moyen (p.m.) d~environ 1 000-60 000 daltons entraînant une plus grande solubilité dans l~eau et le détergent ainsi qu~une capacité à former des émulsions inverses (eau dans huile), trouvant une utilité dans un large éventail de formules ayant des propriétés nettoyantes et une plus grande compatibilité électrolytique et avec le silicone et/ou l~hydrocarbure.
