Properties
Appearance (1), colorless to pale yellow liquid.
Solubility soluble in water; soluble in ethanol.
Stability stable. Under strong acid condition, easily hydrolyzed.
Risk Liquid form: irritation, irritation to skin, eye.
GHS label: 
Ecology may be hazardous to environment. Water body should be given special attention.
Biodegradability biodegradable.
Characteristics excellent emulsifying, dispersing, anticorrosive, antirust, lubricating, cleansing, solubilizing, antistatic, wetting abilities. Low to moderate foaming. Resistance to high concentration of alkali. Can be used as soap substitute. Suitable for preparation of transparent liquid products.
Note (1), Should not be used in children products that can be direct prolonged contact with the skin, such as skin care products.
(2), Avoid using in children cleaning products, such as shampoos.
(3), Do not use in nitrosating environment. Reaction of triethanolamine and nitrous acid can not produce nitrosamines, however, reaction of contained secondary amine of triethanolamine and nitrous acid can produce nitrosamines. Nitrosamine is a carcinogen.
