From the era before humans know use ash and grease boiled together to create have a cleaning and bubble soap. Until today, soap still among around our life. With the rise of environmental awareness, and it gets to make handmade soap began to flourish, so the physical properties of the soap has, cleaning power, efficacy and safety along with taken seriously. This study focused on the properties of handmade soaps, and analyzed and discussed commercial soap to investigate the relationship between the nature. Handmade soap with the most common types of base oils, with each other and then after saponification, the properties test carried out and analyzed the properties commercial soap, choose one have good property handmade soap commercially available comparative correlation with, and then summarized and conclusions. The results:1) Handmade soap ripening need 28 days. 2) The foaming power of base oils: coconut oil (8.2cm)> Palm> olive oil, Hardness : Coconut oil (7820.09mN)> Palm> olive oil, cleaning (△E:4.29)> Palm> olive oil, foam stability: Coconut oil (-0.06cm / min)> Olive Oil> Palm Oil. 3) mixed oil soap, the foaming power and cleaning are better than soap made with oil-based, special of cleaning, C2O0P1 formula it has the most excellent cleaning, foaming and hardness. 4) commercial soap hardness: M1(7992.70 mN)> M3> M2> M4> M5,Foaming: M3 (9.70cm)> M5> M4> M1> M2, Foam stability: M4 (-0.09cm / min)> M5> M3> M1 = M2,Cleaning: M3 (△E15.94)> M5> M4> M2> M1. 5) After a commercial soap efficacy test have increased relative humidity; irritation: M3 (△a: 2.34)> M4> M2> M1> M5, but all belong to the scope of the security does not stimulate. 6) Correlation between the soap, after analysis by the SPSS statistical calculations, which are no significant correlations associated power and detergency remover only highly relevant department. 7) Compared with commercial soap and handmade soap, and found that physical and chemical properties, and commercial soap Cleansing force performance is similar, but in terms of mildness and effectiveness is better than commercial soap, revealing recipes for the production of hand soap recipe C2O0P1 the reference base, the foundation for subsequent research study, and then to develop more high-performance low-irritating soap.
