PEG
polymerPolyethylene glycol (PEG) is a synthetic polymer composed of repeating ethylene oxide units, available in a wide range of molecular weights from liquid to solid forms at room temperature. It is widely used in pharmaceuticals as an excipient for drug delivery and solubility enhancement, in cosmetics and personal care products for humectancy and texture, in food processing as an additive, and in industrial applications including lubricants, hydraulic fluids, and polyurethane foam production. Engineers select PEG for applications requiring water solubility, low toxicity, thermal stability, and compatibility with diverse formulations, making it a versatile choice where biocompatibility and processability are priorities.

Regulatory Screening
Environmental
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.
