Polyethylene Glycol PEG-800 (CAS No.: 25322-68-3) is a non-ionic water-soluble polymer primarily produced by Guoli Chemical, formed by the polymerization of ethylene oxide, appearing as a white waxy solid. With its excellent chemical stability, very low physiological toxicity, and broad compatibility, PEG-800 has become an indispensable functional basic raw material in many industrial fields.
In the pharmaceutical industry, PEG-800 is mainly used as an ointment base, suppository base, and drop pill excipient, effectively regulating drug release rates and improving formulation quality. In the personal care sector, its moisturizing and emollient properties make it widely used in creams, lotions, and facial cleansers, forming a protective film to reduce water evaporation. In industrial manufacturing, PEG-800 plays a key role in metalworking fluids, wire drawing lubricants, and rubber mold release agents by reducing friction coefficients and minimizing mold adhesion.
In the textile industry, PEG-800 is used in sizing and softening finishing processes to improve yarn bundling properties and fabric hand feel. In coatings and ink systems, it serves as an efficient pigment dispersant and leveling aid, preventing pigment flocculation and sedimentation. Additionally, in papermaking and ceramic forming processes, PEG-800 provides lubrication and plasticizing assistance, improving slurry flowability and body forming quality while reducing processing defects.
