Abstract

A process for preparing a vinyl acetate rich polymer for formulating surfactant containing compositions comprising at least one anionic surfactant and having yield stress properties without a significant increase in viscosity, low turbidity, and the ability to suspend insoluble materials in the form of particulates and/or droplets that require suspension or stabilization is disclosed.
