Glycerol, commonly known as glycerol, is an organic substance, colorless, tasteless, sweet, hygroscopic, clear and viscous liquid. Often used as an additive raw material for cosmetics, it can be dissolved with water in any proportion.

Glycerol can absorb moisture in the air, as well as hydrogen sulfide, hydrogen cyanide and sulfur dioxide. Insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oil. The relative density is 1.26362. The melting point is 65438 07.8℃. The boiling point is 290.0℃ (decomposition). The refractive index is 1.4746. Flash point (open cup) 176℃.

Main uses of glycerol:

1. Adhesive: Use its plasticity and permeability.

2. Agriculture: used as spray, soaking agent and detergent.

3. Frost resistance: Use the low freezing point and good compatibility of glycerol.

4. Cleaning and polishing agents: widely used in families and markets.

5. Anti-corrosion: glue and resin used to cover the metal surface.

6. Cosmetics: used as basic materials, emollients, wetting agents, lubricants and solvents, and currently used in skin creams and lotions, shampoos and conditioners, soaps and detergents.

Extended data

Water absorption of glycerol:

1, glycerol's good water absorption is two-way, it can absorb water from the air to moisturize the skin, and it can also absorb water from the skin, so wash your hands and keep your skin moist before applying glycerol.

2, and glycerol is not suitable for long-term dry climate, and the air humidity is too low. Glycerol can not only keep the skin moist, but also make the skin drier.
