Structure
Schematic formula:
Properties
Appearance (1), colorless to pale yellow liquid; or solid.
Solubility insoluble in water to soluble in water. Solubility is related to the degree of polymerization of siloxane, EO number.
Stability stable.
Risk Liquid form: irritation, irritation to skin, eye, respiratory system.
GHS label: 
Ecology may be hazardous to environment. Water body should be given special attention.
Biodegradability biodegradable.
Characteristics excellent emulsifying, dispersing, solubilizing, antistatic, adsorbing, lubricating, film-forming abilities. Performance is related to the degree of polymerization of siloxane, 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.
