Structure
Properties
Appearance (1), white to pale yellow powder.
Solubility soluble in water.
Stability stable.
Risk 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 film-forming, emulsifying, dispersing, lubricating, sustained-release abilities. Polyelectrolyte.
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.
