Dipropylene glycol
Description
Dipropylene glycol (DPG, CAS 25265-71-8) is a low-volatility diol solvent and carrier used across personal care, industrial, and polymer applications. It functions as a humectant, plasticizer, and coupling agent depending on the formulation context.
In personal care and cosmetics, DPG is a primary carrier for fragrance compounds and active ingredients. It improves spreadability and skin feel in lotions, creams, and deodorants while maintaining stability.
Polymer and resin manufacturers use it as a plasticizer and reactive intermediate in the production of polyurethane foams. It is also essential for the manufacturing of unsaturated polyester resins.
In printing inks and packaging coatings, it acts as a slow-evaporating solvent that controls viscosity. This property improves substrate adhesion and ensures consistent application during the printing process.
Lubricant and metalworking formulators incorporate DPG as a base fluid and coupling agent. It is frequently used in cutting fluids and hydraulic formulations to enhance performance and stability.
DPG is supplied as a clear, low-viscosity liquid in drum, IBC, and bulk tanker quantities. Standard commercial grades include industrial and fragrance-grade (FG) for specific manufacturing needs.
Fragrance-grade material meets purity requirements set by IFRA and relevant industry standards. A food-grade specification is also available for applications requiring compliance with FCC standards.
This versatile chemical serves as a reliable component for applications requiring food-contact compliance. Our logistics network ensures timely delivery of high-purity DPG for all industrial sectors.
