Description
N-Methylethanolamine (CAS 109-83-1, EC 203-710-0) is a secondary alkanolamine also known as Methylethylolamine, 2-Methylaminoethanol, and N-Methylaminoethanol. It carries no assigned E-code and is classified under HS code 29221980. The compound belongs to the amine chemical family with molecular formula C3H9NO.
In coatings and adhesives formulations, N-Methylethanolamine functions as a pH buffer, neutralising acidic components to stabilise emulsion systems and extend shelf life. In personal care applications such as hair dyes, it acts as a humectant by attracting and retaining moisture, while also supporting antimicrobial preservation by disrupting microbial cell membranes at controlled pH ranges.
N-Methylethanolamine is supplied as a technical-grade liquid and is subject to REACH registration requirements within the European Economic Area. It is available in standard drum and IBC packaging formats. Procurement teams should verify SDS documentation and confirm supplier REACH compliance prior to import or formulation use.
