Name PEG-47 POLY(1,2-BUTANEDIOL)-66 PROPYLENE GLYCOL Description PEG-47 Poly(1,2-Butanediol)-66 Propylene Glycol is a block copolymer made by reacting propylene glycol with 66 mols of 1,2-butylene oxide, followed by 47 mols of ethylene oxide. It conforms generally to the following formula, where x+y has an average value of 66 and w+z has an average value of 47: Benefits VISCOSITY CONTROLLING Considerations • Ethoxylated Chemical This is an ethoxylated chemical, meaning it’s been created with ethylene oxide, traces of which, along with its carcinogenic byproduct, 1,4-dioxane, can remain in the product.
