About Polyethylene Glycol (PEG) 400 Food Grade (FCC)
Polyethylene Glycol , (C2n H4n+2 On+1 ), is synthesized by ring-opening polymerization of ethylene oxide. This synthesis process gives PEG a range of molecular weights and distributions from 300 grams per mole to 10,000,000 grams per mole.
PEG 400 has a molecular weight of 400 and is a clear, colorless, viscous liquid. Polyethylene Glycol is colorless, inert, odorless, and non-volatile. PEG is biocompatible (it won’t damage tissues or cells), hydrophilic, dissolves readily in water without changing the color odor or taste, and is nontoxic. Due to the high purity of Polyethylene Glycol 400, it is certified by the United States Pharmacopeia (USP) grade and the Food Chemicals Codex (FCC) grade.
Common Uses and Applications
PEG 400 is used in personal care products that need to remain viscous
PEG 400 is used as a food additive and to preserve moisture
PEG 400 is used to readily dissolve hydrophobic drugs
PEG 400 is often used to make viscous lubricants
