Polyethylene glycol (PEG)
Formula:
C2nH4n+2On+1
GOST/CAS:
CAS: 25322-68-3
Polyethylene glycol (PEG) is a versatile thermoplastic polymer available as a viscous liquid, gel, or waxy solid depending on its molecular weight. Known for its exceptional water solubility, low toxicity, and high biocompatibility, PEG serves as a universal binder, plasticizer, antistatic agent, and humectant across various industries. Its unique chemical structure allows it to maintain stability across a wide range of pH and temperature conditions.
Applications
Pharma & Cosmetics: Used as a base for ointments, creams, and toothpastes. Acts as a safe binder in tablets and a reliable humectant in skincare.
Chemical Production: Serves as a vital raw material and intermediate in the manufacturing of polyurethanes, resins, paints, and lacquers.
Textile & Paper: Imparts softness to fabrics, acts as an antistatic agent, and improves the quality of paper coating and sizing.
Metal & Ceramics: Utilized as a high-performance lubricant in metalworking fluids and a temporary binder for ceramic mold shaping.
Key Advantages
High Hygroscopicity: Effectively retains moisture, preventing the drying out of finished products like cosmetics or construction mortars.
Biological Inertness: Non-toxic and non-irritating to skin and mucous membranes, making it ideal for medical and personal care use.
Viscosity Stability: Maintains its physical and chemical properties over a wide range of temperatures and pH levels.
Full Water Solubility: Easily mixes with water in any proportion, forming clear, stable solutions without residue.
Storage & Transportation
- Store in original airtight packaging in a cool, dry, well-ventilated warehouse.
- Protect from direct sunlight, precipitation, and contact with strong oxidizing agents.
- Stable under normal conditions; however, prone to oxidative degradation if exposed to air at high temperatures.
- Transport is allowed by all types of covered vehicles in compliance with freight regulations.
