Caustic Soda

Caustic Soda

This is one of the key Ingredients in cold process soapmaking. Caustic Soda (or Lye) is added to water and then (very carefully!) mixed with our blend of pomace olive oil, organic coconut oil, organic cocoa butter and organic shea butter. It is the caustic soda which causes the chemical reaction of saponification, turning those oils and butters into soap (and glycerine). So, you will not see caustic soda listed as an ingredient on our bars of soap, but you will see sodium olivate, sodium cocoate, sodium cocoa butterate, sodium shea butterate and glycerine.
