Saponification
Saponification is the basic process used to make soaps and certain cosmetic products. In simple terms, it's the chemical reaction that occurs when oils or fats are mixed with an alkali (like lye) to create soap. This is a fundamental skill in cosmetic manufacturing, especially for natural and handmade beauty products. When you see this term on a resume, it typically indicates that the candidate has hands-on experience in cosmetic product formulation, particularly in soap making or related beauty product development.
