Description

Propylene glycol is a colorless, odorless, and slightly viscous organic compound with the chemical formula C3H8O2. It is a diol, which means it has two alcohol groups (-OH) and is used as a solvent, humectant, and viscosity agent in various industries.

Propylene glycol is derived from petroleum, and it is commonly used as a food additive, pharmaceutical ingredient, and in cosmetic and personal care products. It is also used in the manufacturing of polyester resins, antifreeze, and as a solvent for flavorings and dyes.

Propylene glycol is considered safe for use in food, pharmaceuticals, and cosmetics, but it can cause irritation and allergic reactions in some people. It is important to note that propylene glycol is different from ethylene glycol, which is a toxic compound that can cause severe health problems when ingested.
