Liquid dispersion polymer compositions which comprises microparticles of a hydrophilic, water soluble or swellable polymer with a neutralization level of from about 25 % to about 100 %, preferably an acrylic-based polymer, dispersed in a suitable non-aqueous carrier fluid 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. |
