Polyethylene Glycol (PEG), identified by its CAS Number 25322-68-3, is a fundamental chemical intermediate that finds extensive application across a wide spectrum of industries. Its unique combination of properties—including excellent water solubility, biocompatibility, and tunable molecular weights—makes it an indispensable ingredient for formulators and manufacturers. As a premier chemical supplier, we provide high-quality PEG to meet the diverse needs of our B2B clientele.

PEG is a polyether compound synthesized from ethylene oxide. Its structure, H-(O-CH2-CH2)n-OH, allows for a broad range of molecular weights, from liquid forms like PEG200 and PEG400, to solid, waxy materials like PEG1000, PEG4000, and PEG8000. This variation in molecular weight dictates its physical state and suitability for different applications, offering formulators remarkable flexibility.

In the pharmaceutical sector, PEG serves as a crucial excipient, acting as a solvent, binder, lubricant, and viscosity modifier. It is essential in oral, topical, and injectable formulations, often enhancing the solubility and bioavailability of APIs. The process of PEGylation, attaching PEG to therapeutic proteins, is a key strategy in modern drug development to improve drug stability and prolong circulation time.

The cosmetic and personal care industry relies heavily on PEG as a humectant, emollient, and surfactant. It is a common ingredient in moisturizers, creams, lotions, and hair care products, providing hydration and improving product texture. Its non-irritating nature makes it suitable for a wide range of sensitive skin applications.

Industrially, PEG is a vital chemical intermediate. It is a primary raw material for producing ester surfactants, crucial in detergents, emulsifiers, and wetting agents. In the rubber industry, it functions as a lubricant and plasticizer. It also finds use in metal processing, as a component in lubricants and coolants, and in the textile industry as a finishing agent or lubricant. Furthermore, PEG is utilized in the agrochemical sector for pesticide formulations and in pigment manufacturing as a dispersant.
