Glycerin
$ 1.20
Glycerin, also known as glycerol, is a colorless, odorless, viscous liquid with a sweet taste and hygroscopic properties. It is a trihydroxy alcohol (triol) used extensively across food, pharmaceutical, cosmetic, and industrial applications. Food-grade glycerin is produced through hydrolysis, saponification, or transesterification of fats and oils, ensuring compliance with stringent purity standards. It is supplied in bulk (e.g., 250kg drums) for large-scale applications where non-toxic, biodegradable humectants or solvents are required. Glycerin is widely appreciated for its moisture-retaining ability, solubility, lubricity, and stabilizing properties.
