Synthesis method

1. Mainly usedChemical method. It is obtained by saponifying butter, mutton fat and other fats with potassium hydroxide, salting out and separating glycerin.


1. Used as emulsifier and cleaning agent. Used in cream and shampoo cosmetics. It has high emulsifying efficiency , but it easily forms calcium soap when exposed to hard water. It can also be used as fiber softener.

2. It is a potassium catalyst that is widely used in polyisocyanate foam reactions.
