Cosmetic and pharmaceutical foam carrier

Abstract

The invention provides a quick-break, alcohol-free, cosmetic and pharmaceutical foam carrier comprising about 20%-60% hydrophobic volatile solvent, about 20%-60% water, about 3%-20% of polyol, and about 0.1%-7.5% of a surface active agent.

Description

Claims
