Water-soluble or redispersible polymers of unsaturated monomer and silicone polyalkylene oxide derivative, used e.g. in cosmetic formulation, have specified ion exchange equivalent and relationship to molecular weight

摘要

In water-soluble or redispersible polymers (I), obtained by free radical polymerization of ethylenically unsaturated monomers (II) in the presence of silicone derivative(s) (III) containing polyalkylene oxide, the product of the ion exchange equivalent (IEE) and K value of (I) is /- 150 mmole/g; and the IEE is over 2.7 mmole/g and depends on carboxylic acid or carboxylate groups. Independent claims are also included for (a) the production of (I) by polymerizing (II) in the presence of (III) to give (I) with the specified properties; (b) cosmetic, dermatological, hygienic and/or pharmaceutical agents containing (I) besides usual additives.
