Abstract

A superhydrophilic amphiphilic copolymer and process for making the superhydrophilic amphiphilic copolymer includes a low molecular weight polysaccharide modified with a hydrophobic reagent, such as substituted succinic anhydride. The superhydrophilic amphiphilic copolymer system generates stable foam for use in applications, such as healthcare formulations, with low irritation of the eyes and skin.
