Abstract
Abstract A non-toxic, non-eye-irritating bubble composition, consisting essentially of an aqueous solution of from about 1.5 to about 6% by weight of lauric diethanolamide, from about 0.75 to about 3% by weight of an alkanolamido half ester of a sulfosuccinic acid salt as surfactant, from about 0.05 to about 6% of a water-soluble film-forming agent selected from the group consisting of polyvinylpyrrolidone, polyethylenoxide, polyvinylalcohol, cellulose and gelatin, the weight ratio of said lauric diethanolamide to said surfactant on a dry basis being from about 1.74:1 to about 2.4:1, from 0 to about 10% by weight of glycerin, and the balance water.
