When we make our lye soap, we use the cold process method. We first stir all-natural oils with lye until it becomes a perfect pudding-like consistency. We then add fragrance and color, and pour the soap into a mold.
We let the soap saponify for 24-48 hours before cutting it and laying it out to cure (harden) for four weeks.
It sounds like a long process. But, as we all know, good things come to those who wait. And, this is one way to ensure you get an all-natural, lye soap.
What is lye?
Lye is sodium hydroxide, which is a caustic metallic base and alkali salt used to produce soap, paper and other products. While soap must be made with lye, there is no lye in the final product.
What is saponification?
It’s the chemical reaction that occurs between the oils and lye and results in the production of soap and glycerin.
What are the benefits of glycerin?
Glycerin provides natural moisturizing properties, and makes handmade soap unique. Most commercial-made soaps are stripped of their natural glycerin. Factories sell glycerin separately for a greater profit.
