Structure
Properties
Appearance (1), colorless to pale yellow liquid or solid.
Solubility insoluble in water to soluble in water. Solubility is related to PO number.
Stability stable. Under strong acid or strong alkali condition, easily hydrolyzed.
Risk Liquid (or solid) 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 biodegradable.
Characteristics excellent emulsifying, dispersing, solubilizing, lubricating abilities. Low foaming. Performance is related to PO number.
Synthesis
Obtained that stearic acid reacts with propylene oxide.
