Because of the majority composition of the soaps are made by natural materials such as fatty acid esters and essential oils. In this study an extract solution of Chinese soapberry is instead of water to mix with NaOH to form the alkali solution. The mixing ratios of Chinese soap berry extract solution to water are 0%, 20%, 50%, and 100%. The derived alkali solutions then add into the mixture of 30% coconut oil and 70% olive oil with mixing to proceed with the soapy reaction. The characteristics of the soaps with the adding of soapberry extractions are investigated. It is found the adding of the soapberry extractions into the soaps can improve the soap’s characteristics a lot. Comparison the properties of the soapberry soaps with the soap without soapberry extraction. It shows that the soapberry soaps own a better demoulding property, a better structure of compaction, and a better foaming effect than the soap without soapberry. Moreover, the oil oxidation of the residual olive oil in the soap can also be prevented by adding soapberry extraction. It is indicated that the best mixing ratios of soap berry extract solution to water is100% in this investigation.
