Product type
Dipropylene glycol (DPG) is a colorless, odorless liquid that is a type of glycol, primarily used as a solvent and in the production of various chemical formulations. It is produced through the hydration of propylene oxide and is known for its low toxicity and high boiling point. DPG is commonly utilized in the cosmetics, pharmaceuticals, and food industries due to its ability to dissolve a wide range of substances and its stability under various conditions.
