摘要: Rheology modifiers comprising cross-linked poly(amino acid) and methods of their use in aqueous compositions. The modifiers comprise cross-linked poly(amino acid) microparticles having a mean equivalent diameter when fully swollen in deionized water of up to 1000 μm, as measured by laser diffraction. In particular, the poly(amino acid) is D-, L- or D,L-Y-poly(glutamic acid). A method of preparing the modifier comprises cross-linking a poly(amino acid), drying the cross-linked poly(amino acid) and grinding the cross-linked poly(amino acid) to have the required diameter.
