Structure
R: tallow alkyl.
Properties
Appearance (1), pale yellow to yellow liquid to solid.
Solubility insoluble in water to soluble in water. The solubility increases with the increase of EO number. Soluble in acetone, benzene.
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.

Ecology may be hazardous to environment. Water body should be given special attention.
Biodegradability biodegradable.
Characteristics excellent emulsifying, dispersing, solubilizing, antistatic, lubricating, anticorrosive, antirust abilities. Good antibacterial, antimicrobial abilities. Performance is related to EO number. Acid resistance. Low EO: poor resistant to alkali. Low EO: poor compatibility with anionic surfactants.
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.
Synthesis
Obtained that tallow amine reacts with ethylene epoxide.
