DIPROPYLENE GLYCOL | CAS 25265-71-8

Product Overview

Dipropylene Glycol (CAS: 25265-71-8) is a colorless, nearly odorless, hygroscopic liquid belonging to the glycol family. It is a mixture of three isomeric compounds produced as a by-product of propylene glycol manufacturing. DPG is known for its excellent solvency, low volatility, low toxicity, and moderate hygroscopicity, making it a versatile ingredient in industrial and consumer applications.

Product Description

Dipropylene Glycol is a water-white, clear, hygroscopic liquid having low volatility. It is fully miscible with water and many organic solvents such as ethanol, benzene, toluene, and acetone. DPG serves as an excellent solvent, coupling agent, humectant, and chemical intermediate across diverse industries including cosmetics, fragrances, resins, paints, coatings, and functional fluids.

Technical Specifications

Applications

Cosmetics & Personal Care

Dipropylene Glycol is widely used as a solvent, humectant, and viscosity modifier in lotions, creams, deodorants, shampoos, conditioners, and suncare products. It functions as a coupling agent and low-irritation carrier in perfumes, fragrances, skincare products, and hair care formulations.

Paints, Coatings & Inks

DPG serves as a coalescing agent and solvent in water-based coatings, lacquers, printing inks, and paint strippers. Its high boiling point and low vapor pressure facilitate penetration into fibers and promote the production of intense, bright shades in textile printing and dyeing processes.

Resins & Plastics

Acting as a plasticizer, chemical intermediate, and polymerization initiator, DPG is used in the manufacture of unsaturated polyester resins, polyurethanes, and alkyd resins. It adds flexibility and hydrolytic stability to unfinished resin systems.

Functional Fluids

Dipropylene Glycol is applied in hydraulic brake fluid formulations, cutting oils, antifreeze, deicing fluids, and heat transfer fluids due to its low volatility and excellent solvency.

Industrial & Agricultural

DPG functions as a solvent for agricultural chemicals, insecticides, and pesticides. It is also used in industrial soaps, cleaning products, textile lubricants, and as an extraction solvent for aromatics from hydrocarbon mixtures.
