Product Details

Monoethanolamine CAS# 141-43-5

Ethanolamine is a variety of viscous hygroscopic amino alcohol incorporates each amine and alcohol chemical groups. It is extensively dispensed interior the physique and is a thing of lecithin. It has many sorts of industrial applications. For example, it can be used in the manufacturing of agricultural chemical compounds such as ammonia as properly as the manufacturing of prescription drugs and detergents. It can additionally be used as a surfactant, fluorimetric reagent and casting off agent of CO2 and H2S. In pharmaceutical field, ethanolamine is used as a Vascular Sclerosing agent. It additionally has antihistaminic property, which alleviates the bad signs and symptoms brought about through H1-receptor binding.

Product Usage

Ethanolamine is used as an absorption agent to remove carbon dioxide and hydrogen sulfide from natural gas and other gases, as a softening agent for hides, and as a dispersing agent for agricultural chemicals. Ethanolamine is also used in polishes, hair waving solutions, emulsifiers, and in the synthesis of surface-active agents (Beyer et al 1983; Mullins 1978; Windholz 1983). Ethanolamine is permitted in articles intended for use in the production, processing, or packaging of food (CFR 1981).

Ethanolamine undergoes reactions characteristic of primary amines and of alcohols. Two industrially important reactions of ethanolamine involve reaction with carbon dioxide or hydrogen sulfide to yield water soluble salts, and reaction with long chain fatty acids to form neutral ethanolamine soaps (Mullins 1978). Substituted ethanolamine compounds, such as soaps, are used extensively as emulsifiers, thickeners, wetting agents, and detergents in cosmetic formulations (including skin cleaners, creams, and lotions) (Beyer et al 1983).
