Tex Lab Supply PEGs are available in average molecular weights ranging from 200 to 8000 in a variety of viscosities and physical forms. Tex Lab Supply PEGs meet all applicable requirements in the National Formulary (NF) for use in drug applications, Food Chemicals Codex (FCC) requirements for use in certain food applications and personal care products. Chemical Intermediates The primary hydroxyl functionality of Tex Lab Supply PEGs allows reactions typical of alcohols, such as conversion of a functional alcohol group to esters, ethers, amines and acetals. Tex Lab Supply MPEGs have one primary hydroxyl group and can be used to prepare high purity monoesters. All Tex Lab Supply PEGs and MPEGs meet the requirements necessary to produce the highest quality fatty acid esters. Esters based on PEGs provide valuable surface active properties. They are classed as nonionic surfactants and are not affected by acids or hard water, an advantage over anionic or cationic soaps. These characteristics have been found valuable in the textile, agricultural, paper, personal care and cosmetics industries. In addition to fatty acids and fatty acid esters, numerous other compounds can be reacted with polyethylene glycols, including diethyl sulfate, alkyl halides, aryl halides containing nitro groups, and isocyanates. Reaction of PEGs with isocyanates results in the formation of polyurethane polymers. Food Processing and Packaging
