Abstract
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.
