Structure
Properties
Appearance    (1), liquid; (2), solid.
Solubility    soluble in water.
Stability    stable in weak acid, weak alkali, hard water. Under strong acid or strong alkali, easily hydrolyze. Easily oxidized.
Risk    Liquid form: irritation, irritation to skin, eye.
GHS (Rev.6) label:
Ecology    may be hazardous to environment. Water body should be given special attention.
Biodegradability    biodegradable.
Characteristics    excellent emulsifying, dispersing, cleansing, wetting, solubilizing, foaming, permeating abilities. Good lime soap dispersing power. Mild. Suitable for neutral formula system.
Note    (1), Do not use 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.
Synthesis
(1), Esterification reaction
Maleic anhydride reacts with oleamido PEG, obtain oleamido PEG maleate.
(2), Sulfonation reaction
Oleamido PEG maleate reacts with triethanolamine bisulfite(salt), then obtain this product.
