Cold Process Soap, also known as Cold Saponification, is when fats (e.g: oils and butters) create a chemical reaction with Sodium Hydroxide and you end up with soap!
Did you know - Cold processed soap has a history going back to 2800 BC when the ancient Babylonians mixed together fats and ash to make the very first soap!
This method is one of many different ways of making soap. I really enjoy using this method and all of Kandy Krafts Soapery soaps are made using this method.
Cold Process Soap Making can be a long process. After the oils and fats have been combined with the sodium hydroxide and I have added in any fragrance oil/essential oils and colours then the soap needs to sit over night, preferably 24-48 hours, so that the soap goes through a stage called Saponification. This means that the soap is no longer caustic and is safe to touch without the use of gloves
After that, the soap is then cut into bars and left to cure for 4-6 weeks in a well ventilated area. This ensures that any excess water evaporates and you are left with a lovely, hard bar of soap.
