Abstract
Inverse emulsions made by inverse emulsion polymerization have a disperse aqueous phase comprising a solution or dispersion of at least one water soluble polymer, particularly a polymer that forms a viscous solution or dispersion in water, and a continuous oil phase which is or includes an ester oil including an alkoxylated alcohol group. The inclusion of ester oil including an alkoxylated alcohol group provides these oils in emulsions, particularly personal care emulsions made by inversion of the inverse emulsions on dilution with water.
