Polypropylene Glycol

Polypropylene glycol (PPG) is a versatile synthetic liquid made from petroleum. It's part of the glycol family, similar to antifreeze but with different properties. PPG is used in many products, including cosmetics, such as skin creams and hair conditioners, where it acts as a moisturizer or solvent. It also serves as a building block in manufacturing plastics, rubber, and paints. PPG is valued for its stability, low toxicity, and ability to blend well with other ingredients. Properly produced and used, it is safe, but can cause irritation if not handled properly.
