Structure
R: olive oil group.
Properties
Appearance (1), liquid to solid.
Solubility soluble in water.
Stability stable. Easily oxidized.
Risk Liquid form: irritation, low 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, foaming, foam stabilizing, wetting, solubilizing abilities. Good compatibility. Can be compounded with cationic surfactants without affecting each other. Mild surfactant. Can reduce irritation of other surfactants. Under acidic condition, do not affect cleansing, foaming effects. Performance varies with EO number.
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), Can be used in children products.
Synthesis
(1), Chloroacetic acid process (Discontinuous process)
Obtained that PEG olive oil react with chloroacetic acid, sodium hydroxide.
The residual amount of sodium chloroacetate should be controlled in this process.
