Abstract
Water dispersible polyester polymers, polyesteramides polymers and blends of these polymers are dispersed in water and spray dried to form fine powders. In the solid state, these powders can absorb oils and/or diffuse ambient light, thereby resulting in the production of significant reduction in gloss and tack of lipids in cosmetic and personal care products when applied to ordinarily oily skin.
Claims14
A powder comprising a water-dissipatable polyester and/or polyester-amide polymer powder having a particle size of about 0.1 to 100 microns and a T.sub.2 of 50.degree. C. or greater, said powder obtained by spray-drying an aqueous dispersion of said powder.
A method for sequestering water-dissipatable or non water-dissipatable substances, which comprises blending said substance with a water-dissipatable polyester and/or polyester-amide polymer powder having a particle size of about 0.1 to 100 microns and a T.sub.g of 50.degree. C. or greater, said powder obtained by spray-drying an aqueous dispersion of said polymer powder.
