THICKENER FOR HIGH-SURFACTANT AQUEOUS SYSTEMS

摘要

PROBLEM TO BE SOLVED: To provide a thickener for aqueous systems which exhibits preferable stability and advantageous fluidity even in a high-surfactant aqueous system. SOLUTION: An aqueous composition comprising at least 18% surfactant and colloidal inorganic clay is provided. The composition is stable with regard to phase separation at 40°C for at least three months and exhibits increased low shear viscosity relative to a composition without clay. The composition comprises 2-4C alkyl(meth)acrylate residues and at least one lipophilically-modified copolymer containing acrylic acid residues. COPYRIGHT: (C)2004,JPO&NCIPI
