Structure
Properties
Appearance (1), colorless transparent liquid to white paste to white solid.
Solubility insoluble in water to soluble in water. Soluble in ethanol, toluene. Solubility is related to EO number, PO number.
Stability stable.
Risk Liquid (or solid) form: flammable material; irritation, irritation to skin, eye, respiratory system. Harmful products of combustion are CO, CO2 and so on. Contact with strong oxidants, can cause to burn.

Ecology may be hazardous to environment. Water body should be given special attention.
Biodegradability biodegradable.
Characteristics excellent cleansing, emulsifying, dispersing, solubilizing, lubricating, wetting, permeating, antistatic, antifoaming, demulsifying abilities. Performance is related to EO number, PO number. Low foaming. Resistance to non-oxidative acid.
Note (1), The by-product 1,4-dioxane is a possible carcinogen. Generally, can be acceptable when concentration of 1,4-dioxane is less than 30ppm or less.
(2), Be careful with using in children's products.
(3), The STRUCTURE is only schematic. Ethylene oxide and propylene oxide can be random copolymerization or block copolymerization. Block copolymers can end with PEG or PPG.
Synthesis
Obtained by polymerization of ethylene oxide and methyloxirane.
