Synonyms: PEG, poly oxy ethylene, poly ethlyene oxide, Poly(oxy-1,2-ethanediyl),.alpha.-hydro-.omega.-hydroxy, C2nH4n+2On+1, where 2n represents the number of C-atoms in the chain.
Polyethylene glycol is used in many industries: medications (primarily in pill coatings and in some surgical liquids), as thickener in cleaning agents, as a lubricant in hydraulic fluid, to thicken coatings, and even in food (as an antifoaming agent). PEG has the curious property of being able to bind many water molecules along its main body, while the ends remain more hydrophobic. The chain length dictates how many water molecules can be bound, and therefore allows it to be used in a variety of ways. For example, in the coatings industry, PEGs with a molecular weight of up to 400 are used to keep water in paints, so that the paints stay hydrated during the process of applying them. However, PEGs with a molecular weight of 3-4000 are used as thickeners, because their hydrophobic heads form a network with each other which helps immobilize the rest of the paint. In cleaning agents and detergents, PEG is often used as a thickening agent, a penetration enhancer and a water carrier. But again, different uses require different chain lengths.
Historically, the synthesis of PEGs is performed with ethylene oxide and glycol of petrochemical source. Sirius International and its partners managed to perform above mentioned step by exclusively adding ethylene oxide and glycol from vegetal sources. As such, Ethoxybrite PEG biobased is the ideal raw material for any green, 100% sustainable, ecologically certified end product.
Our line Ethoxybrite PEG provides a number of chain lengths to suit your exact application.
Ethoxybrite PEGs are harmless and non-toxic
