Monoisopropanolamine
A basic chemical used in many applications serving as an emulsifier, stabilizer, chemical intermediate, and a neutralizer that achieves basicity, buffering, and alkalinity objectives. It is a liquid product at room temperature, providing neutralization of acidic component and pH contribution to the formulations. Monoisopropanolamine-based formulations can offer better color and heat stability and improved oil solubility than conventional ethanolamines. It is a specialty alkanolamine that acts as a neutralizers for water-based coatings
