Abstract
Abstract Foamable compositions comprising water, and a modified non-ionic cellulose ether prepared as described in U.S. Pat. No. 4,228,277 produce very stable foams. Accordingly, these compositions are suitable for use as foaming personal care products, such as hair styling mousses and foaming hand lotions and cleansers, and in other applications where stable foams are needed. In personal care products, foaming is desirably effected by an aerosol propellant included in the foamable composition.
