Methyldiethanolamine (MDEA) is a dihydroxy functional tertiary amine. It is a versatile intermediate with a variety of applications.
Methyldiethanolamine is used as a co-initiator for type II photoinitiator combinations.
As a neutralizing agent, Methyldiethanolamine increases resin solubility and improves solution stability by reducing pH drift. Additionally, it aids pigment dispersion.
Methyldiethanolamine can be used as a chain extender to synthesize polyol-based polyurethane foams and elastomers.
In metal working fluids, Methyldiethanolamine is used as a pH buffer and an anticorrosion additive.
Methyldiethanolamine forms quat salts with fatty acids, which are applied in fabric softener formulations.
Methyldiethanolamine is used to manufacture softeners, soap emulsifying agents, Lubricants, Paraffin Emulsions, and dyes.
Methyldiethanolamine purifies the gases, particularly natural gas, for the bulk removable Carbon Dioxide and is also used as a scrubbing and extracting agent in Gas treatment.
N-Methyl Diethanolamine MDEA is used in the production of various pharmaceutical products, including anti-malarial drugs
