Triglyceride 3 NaOH / H 2 O Δ 3 × soap 3 × glycerol Triglycerides can be saponified with sodium hydroxide to give glycerol and fatty sodium salt or soap. Typical plant sources include soybeans or palm. Animal-derived tallow is another source. Approximately 950,000 tons per year are produced in the United States and Europe; 350,000 tons of glycerol were produced per year in the U.S. alone ...

USP grade vegetable glycerin is acceptable for Halal certifying and in some instances a Halal standard may (but not always) accept Kosher certified USP Grade vegetable glycerin as meeting Halal standards (i.e. to be Halal 'compliant'). Where the issue of Halal Alcohol-Free versus Haram Alcohol-Removed glycerites is concerned, even though U.S ...
Ethanol has the advantage of being an excellent solvent for both acidic and basic (alkaline) constituents. A tincture using glycerine is called a glycerite. Glycerine is generally a poorer solvent than ethanol. Vinegar, being acidic, is a better solvent for obtaining alkaloids but a poorer solvent for acidic components.

Monoglycerides and diglycerides are types of glycerides both naturally present in food fats, [2] including various seed oils; [3] however, their concentration is usually low and industrial production is primarily achieved by a glycerolysis reaction between triglycerides (fats/oils) and glycerol, [4] followed by purification via solvent-free molecular distillation.
