Polyethylene Glycol (PEG) 4000, Granular, Lab Grade, Kosher

Polyethylene Glycol , (C 2n H 4n+2 O n+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 4000 has a molecular weight of 4000 and is colorless, inert, odorless, and non-volatile. PEG is biocompatible, hydrophilic, dissolves readily in water without changing the color odor or taste, and is nontoxic. The number 4000 mentioned with the Polyethylene Glycol 4000, describes its average molecular weight. Lab Grade chemicals possess reasonable purity but do not comply with any official standard for quality or purity. It is recommended to use Polyethylene Glycol 4000, Lab Grade be used in training institutes, research labs, and for other commercial applications.
