Abstract

A structured aqueous detergent composition comprising modified cellulose and surfactant characterized in that the composition comprises: a) 0.2 to 10 wt %, preferably 0.4 to 7 wt %, anionic surfactant or zwitterionic surfactant or mixtures thereof, b) 0.5 to 5 wt %, preferably 1 to 2 wt %, dispersed modified cellulose biopolymer, wherein the modification consists of the cellulose having its C6 primary alcohols oxidized to carboxyl moieties (acid/COOH—) on 10 to 70% of the glucose units and substantially all the remainder of the C6 positions occupied by unmodified primary alcohols, c) 0 to 10 wt % non-surfactant electrolyte; d) 0 to 15 wt % other conventional detergent composition additives e) balance water. The invention also provides a method to manufacture the composition.
