Properties
Appearance    liquid to solid.
Odor    faint characteristic odor.
Solubility    slightly soluble to soluble in water. The solubility increases with the increase of EO number.
Stability    stable in weak acid and hard water; unstable in strong acid, hydrolyzed; react with alkali to produce the corresponding salts.
Risk    Liquid form: corrosion, irritation, irritation to skin, eye.
GHS (Rev.6) label:  
Ecology    may be hazardous to environment. Water body should be given special attention.
Biodegradability    biodegradable.
Characteristics    excellent cleansing, foaming, emulsifying, wetting, dispersing, solubilizing, foam stabilizing abilities. Resistant to hard water. Performance is affected by EO number, such as: with the increase of EO number, cleansing capability decreases, solubilization capacity increases.
Note    (1), 1,4-dioxane generated during preparation: probable carcinogen. However, can be acceptable when concentration of 1,4-dioxane is less than 30ppm or less.
