Structure
Schematic formula:
Properties
Appearance (1), yellow viscous liquid to solid.
Solubility dispersible in water (slightly soluble in water) to soluble in water. The solubility increases with the increase of EO number.
Stability stable. Easily oxidized.
Risk Solid (or liquid) 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 not easy to degrade.
Characteristics excellent emulsifying, dispersing, solubilizing, wetting, film-forming 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.
Synthesis
Obtained that propenyl nonylphenol reacts with ethylene epoxide.
