The main raw materials of soap include animal fatty acids, sodium hydroxide, synthetic pigments, synthetic spices, preservatives, antioxidants, foaming agents, etc.
The process of making soap is simply to mix one or several animal oils and vegetable oils (such as butter, mutton, coconut oil, palm oil, etc.), and then refine them by refining, decolorizing, deodorizing, and then produce sodium fatty acids after the saponification reaction of caustic soda, then add other auxiliary ingredients and flavors.
Saponification reaction refers to the reaction between alkali and ester, and the products of the reaction are alcohol and carboxylate. This refers specifically to the reaction between oil and alkali. This reaction is an important step in the process of making soap, so it is named.
