Structure
Properties
Appearance (1), liquid to solid.
Solubility insoluble in water to soluble in water. Solubility is related to EO/PO number.
Stability stable. Easily oxidized. Under strong acid or strong alkali condition, easily hydrolyzed.
Risk Solid (or liquid) 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, solubilizing, lubricating abilities. Performance is related to EO/PO number.
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.
