Water soluble polymeric thickeners for products for topical application

Mikolajewicz Roman Joseph, +1 more
TLDR
In this paper, a water-in-oil emulsion containing polymeric material, at least 98% of which is soluble in the aqueous phase, is presented. But the polymeric units are derived from (a) acrylamide, (b) 2-acrylamido-2-methylpropane-sulphonic acid (AMPS) and (c) polyfunctional monomer, present in an amount of from 0.12 to 2 milliequivalents per mol of total monomer units.
Abstract: 
A thickener for products for topical application such as personal care products for application to the skin or hair, or topically administrable pharmaceutical preparations, comprises a water-in-oil emulsion containing polymeric material, at least 98% of which polymeric material is soluble in the aqueous phase. The polymeric material comprises units derived from (a) acrylamide, (b) 2-acrylamido-2-methylpropane-sulphonic acid (AMPS) and (c) a polyfunctional monomer, present in an amount of from 0.12 to 2 milliequivalents per mol of total monomer units. At least some of the AMPS units are in the form of a neutral salt such that the aqueous phase of the water in oil emulsion has a pH of at least 5.5.
