Abstract
Liquid dispersion polymer compositions which comprise microparticles of a hydrophilic, water soluble or swellable polymer, preferably an acrylic-based polymer, dispersed in a di- or triglyceride oil such as soybean oil and an oil-in-water surfactant, are useful to prepare microparticulate thickening systems to thicken aqueous or aqueous/organic compositions, particularly for use in personal care and pharmaceutical formulations. The preparation and the use of these liquid dispersion polymer compositions is described.
