what is Diethanolamine ?

1.Diethanolamine (DEA) is a polyfunctional product that is a secondary amine and a diol and acts as a weak base.

2.Diethanolamine buffer (10 mM diethanolamine, 0.5 mM MgCl2, pH 9.5) is frequently used in colorimetric assays (ELISA) using p-nitrophenyl phosphate (PNPP, sc-3720) substrate and diethanolamine buffer.

3.DEA (5% diethanolamine, pH 11.5) may also be useful for the dissociation of antigen-antibody complexes. For surface staining of monoclonal antibody-alkaline phosphatase conjugates by flow cytometric analysis,

4.diethanolamine buffer (pH 9.6) has been used with BCIP/NBT (sc-24981) substrate.

5.sed as an absorbent for acid gases and as a chemical intermediate.




1. Added in shampoo and hand washing, it can not only stablize foam and thicken the liquid, but also will reduce the irritation to skin.

2. for it can soften fibre textile, it is especially suitable for washing animal’s fibre, such as hair and thread, etc.

3. Its applications are in liquid detergent, shampoo, dishware detergent, liquid soap, fibre modifier, wool cleanser and metal rinser, etc.

4. Also uded in electric plating, shoe polish and printing ink etc.

5. In pharmaceutical industry, it is used as raw material for corrosion inhibiter; in synthesize highelastic froth of polyaminoester used as cross-linking agent; mixed with triethanolamine, used as decarburizing agent for engines of airplanes Reacts with fatty acids, to form amides of alkyl alcohol. Also used as raw material in organic synthesis to produce surface activators and absorbents for acid gases.




1.Used as analytical reagent,acidic gas absorption agent.

2.used for coke gas purification of industries,and can Be recycled.

3.used for making detergent, Polish, lubricants, softeners, surfactants, etc.,

4.used for organic synthesis.

5.In shampoo and light detergent foam is used as thickener improver,used as a softening agent in the synthetic fiber and leather production.
