Structure
Properties
Appearance (1), solid; or liquid.
Solubility slightly soluble to soluble in water.
Stability stable. At strong acid, strong alkali, easily hydrolyzed.
Risk 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.
GHS label: 
Ecology may be hazardous to environment. Water body should be given special attention.
Biodegradability biodegradable.
Characteristics excellent emulsifying, dispersing, wetting, solubilizing, lubricating abilities. Performance varies with EO number.
Note (1), 1,4-dioxane generated during polyether preparation: probable carcinogen. However, can be acceptable when concentration of 1,4-dioxane is less than 30ppm or less.
