About
A monoethanolamine-neutralized coconut fatty acid soap. Mild cleanser but carries MEA nitrosamine-precursor concerns.
MEA-cocoate (CAS 66071-80-5) is the monoethanolamine salt of coconut fatty acids — essentially an MEA-soap. MEA is a primary alkanolamine that, like its di- and tri- relatives, can react with nitrosating agents (2-bromo-2-nitropropane-1,3-diol, DMDM hydantoin, formaldehyde donors) to form nitrosamines — some of which are IARC-listed. EU SCCS specifically flags MEA/DEA/TEA surfactants for nitrosamine control and restricts use alongside nitrosating preservatives. CIR considers ethanolamine cocoates safe as used provided residual free amine is controlled and nitrosating combinations are avoided. Mostly found in rinse-off cleansers.

Known concerns
- Monoethanolamine (MEA) salt — secondary amine with nitrosamine-formation risk if combined with nitrosating agents
