The convenience of melt-and-pour soap base might keep you away from good old fashioned cold process soap-making. But why would you pick the longer, more challenging path?
Easy: you get better quality soap for less money!
Cold process soap is made by combining lye with oils and butters, in a chemical reaction known as 'saponification'. This process gives you complete control over the ingredients, and it allows the use of fresh additions, such as milk or even fruit. It results in a highly moisturizing soap that's good for both the skin and the environment.
Soap making process can be customized with swirls of frosting, among others, and it can also hold heavier additives due to its thicker texture. Through the long curation process, cold process soap will also keep for a long time - so while you do have to put it more effort, you'll be reaping the benefits of your work for longer.
One more thing: buying the raw ingredients for cold process soap is generally less expensive than a melt-and-pour base! Scroll down for our best cold process soap recipes to get you started:
