Propylene Glycol

Propylene Glycol (CAS No. 57-55-6) is a versatile chemical widely used in food, pharmaceutical, cosmetic, and industrial applications. It functions as a solvent, humectant, and carrier ingredient, helping improve product stability, moisture retention, and performance across a wide range of formulations and manufacturing processes.

Propylene glycol is widely used in the food industry as a multifunctional ingredient. It acts as a solvent, humectant, and carrier for flavors, colors, and additives. Its ability to retain moisture and improve ingredient dispersion helps maintain product stability and consistent quality in many processed foods.

1, 2-propanediol has good viscosity and hygroscopicity, and is widely used as a hygroscopicity, antifreeze, lubricant, and solvent in food, pharmaceutical, and cosmetic industries.

In the food industry, 1, 2-propylene glycol and fatty acids react to produce propylene glycol fatty acid ester, mainly used as a food emulsifier.
