Bis(2-hydroxypropyl) ether

Bis(2-hydroxypropyl) ether (CAS 110-98-5), commonly known as DPG or dipropylene glycol, is a diol solvent and humectant used across personal care, coatings, and polymer manufacturing. It functions primarily as a carrier and coupling agent. This chemical enables the uniform dispersion of active ingredients and additives across a broad range of formulations. In personal care, it acts as a solvent and humectant in lotions, fragrances, and skin-conditioning products.

The material improves spreadability and moisture retention in various cosmetic applications. Coatings and adhesives formulators use it as a reactive diluent and plasticizing co-solvent to control viscosity and enhance film flexibility. In polyurethane production, it serves as a chain extender and polyol building block, influencing the mechanical properties of foams, elastomers, and sealants. It also functions as a stabilizer and carrier in UV-absorber systems.

The product is utilized in preservative blends where solubility of actives is a formulation constraint. It is supplied as a clear, low-viscosity liquid in drum and IBC quantities for industrial use. Bulk tanker supply is available for high-volume industrial buyers requiring consistent delivery. Standard commercial grades include industrial/technical and cosmetic-grade, with the latter meeting purity requirements for personal care.

Specifications are aligned with recognized industry standards for glycol-based solvents across major markets. This ensures reliability and performance for manufacturers across the global chemical supply chain.
