(57) [Summary] [Purpose] From the standpoint of preventing pollution of the natural environment, the synthetic surfactants used in foam products are changed to naturally derived raw materials. [Structure] Saponin was selected as a naturally-occurring foaming agent, and the conditions under which good foam was produced were determined based on research experiments. A stock solution having a saponin concentration of 0.08 to 10 wt% and a pH of 3.2 to 10.2 can be used as a pump type homer or an aerosol type. Furthermore, the higher aliphatic alcohol / higher aliphatic fatty acid is added to 0.0 It was revealed that 1 to 5 wt% was added to form a good foam. |
