Molecular Formula & Molecular Weight
Molecular Formula: N/A
Molecular Weight: N/A
R: wheat germ oil group.
Appearance    (1), solid; (2), liquid.
Solubility    soluble in water.
Stability    stable in weak alkali, weak acid, hard water. Under strong acid or strong alkali, easily hydrolyze. Easily oxidized.
Risk    Solid form: flammable material; irritation, low irritation to skin, eye. Harmful products of combustion are CO, CO2 and so on. Contact with strong oxidants, can cause to burn.
GHS (Rev.6) label:  
Ecology    may be hazardous to environment. Water body should be given special attention.
Biodegradability    biodegradable.
Characteristics    excellent wetting, emulsifying, dispersing, cleansing, foaming, solubilizing, permeating abilities. Good lime soap dispersing power. Suitable for neutral formula system. Mild surfactant.
(1), Esterification reaction
Maleic anhydride reacts with wheat germamido MEA, obtain wheat germamido MEA maleate.
(2), Sulfonation reaction
