Ester Hydrolysis
Saponification is basically ester hydrolysis, the place the ester bonds of triglycerides are cleaved by a base, sometimes sodium hydroxide (NaOH) or potassium hydroxide (KOH). This course of breaks down the rendered pig fats into glycerol and fatty acid salts. The fatty acid salts are the energetic elements that present the cleansing motion.
-
Fatty Acid Composition
The particular fatty acid composition of the rendered pig fats straight influences the ensuing product’s traits. Lard primarily consists of saturated (palmitic, stearic) and monounsaturated (oleic) fatty acids. The ratio of those acids impacts bar hardness, lather high quality, and cleaning means. A better proportion of saturated fat sometimes leads to a tougher bar.
-
Alkali Choice and Focus
The selection between NaOH (for bar cleaning soap) and KOH (for liquid cleaning soap) and the exact focus of the alkali are paramount. The correct quantity ensures full saponification, changing all accessible triglycerides. Inadequate alkali leaves unsaponified fats, whereas extreme alkali leads to a harsh, irritating product. Exact measurements and calculations are due to this fact obligatory for a secure and efficient formulation.
-
Glycerin Manufacturing
Glycerin, a byproduct of saponification, is a humectant, drawing moisture to the pores and skin.
