Structure
Properties
Appearance (1), colorless to pale yellow liquid to solid.
Solubility soluble in water.
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.
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 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.
Synthesis
Obtained that beta-D-methyl glucoside reacts with ethylene epoxide.
