    • PURPOSE: Provided is an aqueous composition containing a surfactant at high concentration, which has excellent stability and rheological property and shows low shear viscosity. CONSTITUTION: The aqueous composition comprises: (a) 18-60% of at least one surfactant; (b) 0.1-10% of at least one copolymer comprising 2.5-30% of an acrylic acid residue, 10-80% of a C2-C4 alkyl (meth)acrylate residue and 2-25% of a oleophilic modified (meth)acrylate residue; and (c) 0.08-0.9% of clay. Particularly, the clay has a particle size of a colloidal range and is preferably synthetic hectorite clay material. More particularly, the aqueous composition comprises 20-45% of the surfactant(s).
