LOW TEMPERATURE PROCESS FOR PRODUCING DRY CELLULOSE ETHER BASED FOAMS

摘要

A composition comprising a gelling agent is provided. The gelling agent consists essentially of a cellulose ether based gelling polymer and the composition is a rigid foam at 20 degrees Celsius. The composition may also comprise an active ingredient. Also provided is a process of making the composition comprising drying a foamed liquid composition comprising the gelling agent at low temperatures. The foamed liquid composition may also comprise an active ingredient.
