What is Dipropylene Glycol and What is Its Use?

What is Dipropylene Glycol (DPG)?

Dipropylene glycol (DPG) is a clear, colorless, viscous liquid that belongs to the class of organic compounds called glycols. It is a derivative of propylene oxide and has the chemical formula C₆H₁₄O₃. DPG is a diol, which means it contains two hydroxyl (OH) groups. It is odorless and has a low vapor pressure.

DPG is commonly used as a solvent, plasticizer, and diluent in a variety of industries and applications. It has excellent solvent properties and is miscible with water, alcohol, and many other organic solvents. DPG is often used as a solvent for dyes, resins, and oils, and as a diluent for fragrances and perfumes. It is also used in the formulation of personal care products, such as skin creams, lotions, and hair care products.

DPG has a relatively low toxicity and is considered safe for use in various applications. However, like other glycols, it can be irritating to the skin and eyes, and excessive inhalation of its vapors should be avoided. DPG should be handled and stored in cool, well-ventilated areas away from sources of ignition.
