The traditional manner of making batch soap adding only refined ingredients which have been balanced chemically to each other. This process has the advantage of being energy efficient as no external heat is applied. This process produces its own natural heat that effects the formation of soap. The cold process yields no waste products of any kind.
A byproduct of making soap out of natural ingredients. Glycerin is a skin moisturizer and is only present in soaps made by the cold-process.
The name of the soap making reaction.
