Abstract

Abstract A mild skin-cleansing aerosol mousse-forming emulsion providing benefits in leaving the skin after washing feeling not taut and dry, but moisturized, soft and smooth. The product also provides abundant rich creamy foam. The cleansing mousse emulsion comprises: A. 88% to 97% of a concentrate containing by weight of the concentrate: 1. from 3% to 20% of a mild nonsoap anionic or amphoteric surfactant; 2. a polymeric skin feel aid at 0.05% to 5%; 3. a moisturizer at 10% to 60%, preferably glycerin; 4. the balance water; and B. from 3% to 12% of a propellant by weight of the total emulsion.
