Have you ever heard of the need for caustic soda to make soap? Well, here it is. Sodium hydroxide (NaOH) is a white, crystalline substance widely used in soap making.
Sodium hydroxide is a key ingredient in the saponification process that is used to create our palm-free, vegetarian soap base. It starts with rapeseed and coconut oils that are made up of triglycerides, which are compounds made of fatty acids and glycerine. When heated together, triglycerides and sodium hydroxide react and create a fatty acid salt, which is more commonly known as soap, and leave all the glycerine aside.
