Information:
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 3000 to 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.
Innovation:
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, palm oil free, ecologically certified end product. Sirius' Ethoxybrite PEG products do not involve any petrochemicals.
Our line Ethoxybrite PEG provides a number of chain lengths to suit your exact application.
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.
Technical:
Ethoxybrite PEGs are harmless and non-toxic
Commercial:
Packaging: 25kg bags

Do you know how gunpowder was created? The Chinese emperor Wu Di (156-87 B.C.) wanted to have eternal life. He invested a significant number of resources, and his alchemists did a lot of unsuccessful experiments mixing and heating Sulphur and Saltpeter. Way later, during the 8th century, the idea was developed, and charcoal was added to the mixture. This substance also didn’t grant eternal life but at least proved itself useful in treating skin conditions and killing insects. Until, by chance, the alchemists found its explosive properties. This story demonstrates one of the ways to achieve significant innovation – by accident. However, there’s another, more successful way, which ensures having control over the process and managing the risks. The Sirius way! Our innovation process includes multiple small and well-considered steps rather than one big and dangerous jump. This step by step approach allows us to take fewer risks and to control our investment throughout the whole process.

The Innovation Process of Sirius
The Sirius Effect: We discuss consumer behavior a lot in these blogs, because most of our customers make products designed for those markets. However, the commercial cleaning industry is a huge one, where one business making the switch will have a much bigger impact on the environment than one consumer. Going green also happens to be good business, too. Building your brand these days requires satisfying increasingly conscious end users more than merely cutting costs.
