Structure
Properties
Appearance (1), liquid; or solid.
Solubility slightly soluble to soluble in water.
Stability stable.
Risk Liquid form: irritation, irritation to skin, eye.
GHS label: 
Ecology may be hazardous to environment. Water body should be given special attention.
Biodegradability biodegradable.
Characteristics excellent cleansing, emulsifying, dispersing, wetting, permeating, solubilizing, lubricating abilities. Performance varies with EO number, PO number. The foaming ability can be controlled by adjusting EO/PO ratio.
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.
(2), Should not be used in children products that can be direct prolonged contact with the skin, such as skin care products.
(3), Avoid using in children cleaning products, such as shampoos.
(4), Do not use in nitrosating environment. Reaction of monoethanolamine and nitrous acid can not produce nitrosamines, however, reaction of contained secondary amine of monoethanolamine and nitrous acid can produce nitrosamines. Nitrosamine is a carcinogen.
