Product Description

Product Description

Polyethylene Glycol (PEG)

Chemical Name: Polyethylene glycol
CAS No.: 25322-68-3
Synonyms: PEG, Poly(ethylene oxide), Macrogol, Carbowax, Polyglycol 

Chemical Properties

• Appearance: Colorless, odorless viscous liquid (low MW) to waxy solid (high MW) 

• Solubility: Highly soluble in water, ethanol, and polar solvents; insoluble in fats and hydrocarbons 

• Thermal Stability: Stable up to 200-240°C; degrades at 300°C 

• Hygroscopicity: Absorbs moisture, especially in low-MW forms 

Key Characteristics

• Non-toxic & Biocompatible: Widely used in pharmaceuticals and cosmetics 

• Versatile Solubility: Acts as a solvent, thickener, and stabilizer 

• Low Immunogenicity: Reduces protein aggregation in drug formulations 

Applications

1. Pharmaceuticals:

   • Drug delivery (PEGylation improves drug solubility and half-life) 

   • Laxatives (PEG 4000/6000 as osmotic agents) 

   • Ointments, suppositories, and tablet coatings 

2. Cosmetics:

   • Moisturizer in creams, lotions, and shampoos 

   • Lubricant and viscosity modifier 

3. Industrial Uses:

   • Lubricants, plasticizers, and surfactants 

   • Oil drilling fluids and textile processing 

4. Biotechnology:

   • Cell fusion and DNA transformation in research 

   • Protein purification and cryoprotection
