Process for the preparation of lipoid ethylcellulose gels and pharmaceutical, cosmetic and industrial use thereof

摘要

A process for the preparation of lipoid ethylcellulose gels is described. The gels are obtained by dissolving ethylcellulose in hydroxyl group-containing lipoid solvents, preferably in fatty alcohols or castor oil. Other lipoid media such as triglycerides or paraffins or fatty esters (waxes) can be added to the solutions. The use of the preparations thus obtained is described for pharmaceutical or cosmetic or industrial purposes.
