Clear, homogenized, flowable hydrogel of crosslinked N-vinyl lactam polymer

摘要

This invention relates to a crosslinked N-vinyl lactam polymer in the form of a stable, clear, flowable homogenized hydrogel composed of microparticles which can be passed through a screen of between about 40 and about 350 mesh size. The invention also concerns a clear, colorless, hydrogel which is required as a carrier for a cosmetically or pharmaceutically active substance such as a hair or skin conditioner and cosmetic or pharmaceutical skin base.
