Uses:
(1) It reacts with fatty acids to form fatty acid isopropanolamide (alkyl isopropanolamide) and esters. Due to its excellent foaming properties, foam stability and ability to dissolve oils, it can be used as an industrial synthetic detergent.
(2) The product obtained from the reaction with thioglycolic acid can be used as a base for cosmetics.
(3) Due to its good hygroscopicity and weak alkalinity, it can be used as a raw material for surfactants, as well as a refining agent, antistatic agent, dyeing auxiliary and fiber wetting agent in the fiber industry.
(4) Its phosphate and nitrite can be used as antioxidants for various lubricants and cutting oils.
(5) The reaction products with various acids and higher fatty ketones can be used as plasticizers, emulsifiers and solvents. Isopropanolamine mixtures have a particularly strong ability to dissolve hydrocarbons. When kerosene, halogenated hydrocarbons, naphtha, etc. are stirred in water with isopropanolamine (4%) and oleic acid (15%), a stable emulsion can be obtained. The salts formed with long-chain fatty acids can be used as emulsifiers for vinyl acetate resins, and the emulsions have good stability and stable color.
