saponified meaning: turn (fat or oil) into soap with
sodium hydroxide also called Lye.
Modern soap makers use a standardized lye, called sodium hydroxide.
You may wonder, as I did, how a strong substance such as lye can produce soaps gentle enough to use on even the most sensitive skin types.
While it doesn’t seem to make sense at first thought, from a chemistry standpoint it’s absolutely necessary. You must use a highly alkaline solution, such as sodium hydroxide, in order to transform oils into soap. In the presence of heat and water, the fatty acids and glycerol in oils bond with the sodium and hydroxide portions of lye to form brand new substances—soap, plus glycerin—which are great for your skin.
No lye remains in the final soap.
