Properties
Appearance (1), pale yellow to yellow-brown liquid to solid.
Solubility insoluble in water to soluble in water. The solubility increases with the increase of EO 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 (Rev.10) 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 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.
(2), Be careful with using in children's products.
