Aerosol gel shaving cream

The invention relates to foam stabilized compositions containing (a) a high foaming nonionic surfactant which is a block copolymer that is an alkylene oxide adduct of ethylene glycol, propylene glycol, or diethylene glycol, and (b) a foam-stabilizing amount of an amine oxide derived from a fatty alcohol which has been oxyethylated to the extent that ethylene oxide units account for approximately 50 to 75 weight percent of the molecular weight of the fatty alcohol-ethylene oxide adduct. The compositions are useful in the formulation of various products in which foam stability is needed, such as hand detergent bars, hair shampoos, rug shampoos, hand dishwashing detergents, etc..

Foam-stabilized compositions

Mouthwashes are disclosed which utilize a polyoxyethylene-polyoxybutylene block copolymer wherein the polyoxybutylene portion of the compound has a molecular weight of at least about 500 and the polyoxyethylene portions contribute from about 50 to 90 percent by weight of the compound. Unexpectedly, the nonionic surfactants solubilize flavoring oils at temperatures below 8.degree. C. so that the mouthwash compositions of the invention remain clear and haze free even when stored at low temperatures.

Mouthwash composition

The instant invention relates to water-in-oil emulsions which are non-irritating to the skin, low in toxicity, colorless and easy to wash off, which contain as the emulsifying agent a polyoxyalkylene compound of the formula:
