Polyethylene Glycol 200 (PEG)

Product Overview

Polyethylene Glycol 200 (PEG 200) is a high-purity, low molecular weight polymer essential for industrial formulation and processing. A clear, colorless, and viscous liquid, PEG 200 functions as a versatile solvent, humectant, and lubricant. It is characterized by excellent solubility in water and various organic solvents, low volatility, and high thermal stability.

Alliance Chemical supplies PEG 200 that meets USP-NF Monograph and Food Chemical Codex (FCC) standards, ensuring the strict impurity control (trace metals, chlorides, sulfates) required for regulated industries. Whether used as a carrier in chemical processing, a plasticizer in ceramics, or a lubricant in textile manufacturing, this product delivers consistent viscosity (50-70 cP at 25°C) and performance.

Common Industrial Applications

• Chemical Processing & Formulation: Serves as a hydrophilic solvent and carrier for varied chemical reactions and formulations due to its stable molecular structure.
• Industrial Lubrication: utilized as a water-soluble lubricant for rubber molds, textile fibers, and metalworking operations where easy wash-off is required.
• Humectant & Plasticizer: Acts as a moisture-retaining agent in adhesives, paper coatings, and ceramic manufacturing to prevent drying and cracking.
• HPLC Mobile Phase: Used in reversed-phase chromatography for the separation of organic compounds.
• Pharmaceutical & Cosmetic Excipient: Functions as a solvent, vehicle, and viscosity modifier in creams, lotions, and liquid preparations (conforming to USP-NF standards).

Safety & Handling

While Polyethylene Glycol 200 is generally considered low-toxicity, standard industrial safety practices must be observed. Store in a cool, dry, well-ventilated area away from strong oxidizing agents to prevent degradation. The product is hygroscopic; keep containers tightly closed to prevent moisture absorption.

Operators should wear appropriate Personal Protective Equipment (PPE), including safety glasses and gloves, to avoid direct contact. In case of contact, rinse thoroughly with water. Refer to the Safety Data Sheet (SDS) for full handling, storage, and emergency response guidelines.
