概要

詳細

Glycerol, or glycerin, is a chemical compound of the formula HOH 2 C-CHOH-CH2OH. It is a colorless liquid, viscous and odorless sweet taste and low toxicity, used in many pharmaceutical compositions. Its molecule has three hydroxyl corresponding to three alcohol functions responsible for its solubility in water and its hygroscopic nature.

In cosmetics, glycerol is often used as a moisturizer, solvent and lubricant. In food it often replaces sorbitol as a sweetener because it has a better taste. This product is also used in toothpaste, mouthwash, moisturizers, hair products and as a component of glycerin soaps, including Marseille’s soap

Glycerol is also used as a humectant (to retain moisture), solvent (aroma carrier), emulsifier, stabilizer and thickener in a wide variety of food products. In water based paints, it is used to slow the drying time.
