n-Butylethanolamine

N-Butylaminoethanol (CAS 111-75-1, EC 203-904-5) is a primary alkanolamine also referenced under the names 2-butylaminoethanol, butylethanolamine, and NSC 1098. It carries no assigned E-code and is classified under HS code 29221990 within the broader amines category.

In metalworking fluids, it functions as a corrosion inhibitor and pH buffer, neutralising acidic byproducts that would otherwise attack ferrous surfaces. In waterborne coatings and adhesives, it acts as an emulsifying agent, stabilising resin dispersions and improving film formation by controlling interfacial chemistry between aqueous and organic phases.

N-Butylaminoethanol is supplied as a technical-grade clear liquid and falls under REACH registration requirements for supply within the European Economic Area. Procurement quantities typically range from drum to IBC and bulk formats. Buyers should confirm supplier SDS documentation and purity specifications prior to formulation use.
