The invention belongs to the technical field of liquid washing cosmetic and discloses bath foam not containing dioxane. The bath foam comprises the following components by weight percentage: 5-14% of sulfonate type anionic surfactant, 0.5-5% of N-sodium cocoyl sarcosinate type anionic surfactant, 2-5% of ampholytic surfactant, and 0.5-3% of alkyl alcohol amine type nonionic surfactant, wherein the sum of the weight percentage of four surface active agents is not less than 12%. In the bath foam, the sulfonate type anionic surfactant is used as a main surfactant, the common fatty alcohol-polyoxyethylene ether sulfate is replaced, simultaneously the N-sodium cocoyl sarcosinate type anionic surfactant and the ampholytic surfactant are added to reduce irritation of the system, so that the product is moderate, does not contain dioxane and has good safety.
