DEA
This ethanolamine is manufactured by reacting ethylene
oxide (EO) and ammonia (NH3). It is reacted with fatty acids to
form amides which are used extensively as a foam stabilizer, emulsifier
and viscosity builder in dishwashing liquids, shampoos and cosmetics.
DEA is also used in such application as gas conditioning, metalworking
fluids and agriculture products. Carbonyl sulfide and carbon disulfide
may react irreversibly with DEA.
