Cold Process Soaps

How to Make Cold Process SoapInterested in Cold Process soapmaking? Cold Process or CP soap is our first and true love here at Bramble Berry. Anne-Marie (owner & founder of Bramble Berry) has made thousands of pounds of soap and really knows what goes into making a beautiful and luxurious bar of soap. In a nutshell, Cold Process soap is made by mixing fatty acids and sodium hydroxide (oil & lye) which then triggers the saponification process. Sounds like magic, but really it's all chemistry. But you don't have to be a scientist to make soap! You just need to know and understand a few basic principles and safety precautions.
