Pulvurent effervescent topical treatment composition
The pulvurent effervescent topical treatment compositions comprise: at least 50% wt. of a gas generating system which comprises both a gas generating constituent as well as a complementary reactive acid constituent, which constituents, when combined in the presence of water or another largely aqueous medium generates a gas, preferably carbon dioxide; 5-50% wt. of an anionic soap and/or anionic surfactant constituent; 0.0001-1.5% wt. of an antimicrobial constituent; 0.0001-3 an exogenous product of Sclerotium rolfsii, and, optionally one or more filler constituents, preferably based on materials which are inert with respect to the gas generating constituent and which also are inert with respect to the antimicrobial constituent; further optionally, one or more further constituents which may be included to provide a desired aesthetic benefit, e.g., a fragrance, colorant and/or a desired technical benefit, e.g. an abrasive, to the pulvurent effervescent topical treatment compositions of which they form a part. The invention also provides effervescing, foamed topical treatment composition which are used as topical treatment compositions.
