Structure
R: palm kernel oil group.
Properties
Appearance (1), pale yellow to yellow liquid; or solid.
Solubility soluble in water.
Stability stable.
Risk Liquid form: irritation, low irritation to skin, eye.
GHS label: 
Ecology may be hazardous to environment. Water body should be given special attention.
Biodegradability biodegradable.
Characteristics excellent cleansing, emulsifying, dispersing, solubilizing, foaming, antirust, anticorrosive, wetting, permeating abilities. Good compatibility. Resistance to hard water. Mild surfactant. Suitable for “non-sulfate” formula system.
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.
