Monoethanolamine (MEOA) belongs to the class of ethanolamines, with both primary amine and hydroxyl functionality.


Monoethanolamine (MEOA) is used as a building block, ph-control agent as well as a dilution agent.


MEOA is used as a pH control agent in the formulation of packaging and printing inks.


Ethanolamines combine the properties of amines and alcohols in one molecule. They exhibit the unique capability of undergoing reactions common to both groups (bifunctioncal). As amines, they are mildly alkaline and react with acids to form salts or soaps. As alcohols they can be transformed to ethers and esters. Ethanolamines are miscible with water, most alcohols and polyols.
Most of their industrial applications are dependent to some degree on these features.

Applications include the production of wood-treatment chemicals, detergents and surfactants.

Products are offered pure and in solutions with water.

As the newest unit at BASF Verbund site in Geismar, Louisiana, methylamines started production in 2012. Methylamine is used in the production of agrochemicals, personal care products, detergents, pharmaceuticals, textiles, solvents and animal feed additives.
