Glycerin
It is actually a by-product of the soap making process. What normally happens is that the lye mixes with water and that solution is added to oil. The water assists the oil and lye to form a chemical bond. What remains from this bond is glycerin and would be considered a by-product of the process.
This glycerin remains within the bar of soap. Unless you’re a large soap manufacturer because they will remove glycerin from their soaps. This makes the bar harder and has it lasting longer in your bathrooms. However individuals who hand make soaps love Glycerin. Usually we combat any softness in a bar of soap by using palm oil which gives the homemade bar added hardness and extends its use in your shower or bath.
Glycerin is a humectant, which means it attracts water and if it’s on your skin it helps to keep it hydrated. It also has emollient properties. Personally, we are a fan and we use it in both out soaps and body butters.
