poly(oxyethylene)

polymer

Poly(oxyethylene), commonly known as polyethylene glycol (PEG) or polyethylene oxide (PEO), is a synthetic linear polyether characterized by repeating ethylene oxide units. It is a water-soluble, semi-crystalline polymer available across a wide range of molecular weights, from liquid oligomers to solid polymers, making it highly versatile. The material is widely used in pharmaceuticals as a binder and solubilizer, in cosmetics and personal care products, as a lubricant in manufacturing processes, and in biomedical applications including drug delivery systems and tissue engineering scaffolds. Engineers select poly(oxyethylene) for its biocompatibility, ease of processing, excellent solubility in polar solvents, and ability to reduce friction and improve flow characteristics in formulations.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
