Cosmetic composition that reacts to soap
WIPO Patent Application WO/2015/163565
Publication date: Oct. 29, 2015
Assignee: New & New Co., Ltd
Disclosed in this patent application is a composition including an aqueous phase and an oil phase. Specifically, the aqueous phase includes a water-soluble polymer, a water-repellent powder and purified water. The oil phase includes oil, a hydrophilic emulsifier having an HLB number of 8 to 18, and a lipophilic emulsifier having an HLB number of 2 to 6.
According to the inventors, this invention forms a soap-sensing layer by dispersing the water-repellent powder in the aqueous phase and simultaneously using the hydrophilic and lipophilic emulsifiers.
Since the soap sensor reacts with a saponification group in soap, this composition has an advantage over conventional compositions in that it enables convenient washing even when used only once.
