TEA-Lauryl Sulfate
Triethanolamine dodecyl sulfate
Triethanolamine (TEA) counterion raises significant concern: TEA can react with nitrosating agents (certain preservatives, contaminating nitrites) to form nitrosamines, which are potential carcinogens. EU regulations restrict TEA levels to control nitrosamine formation. Irritation profile similar to SLS. Considered an older formulation technology; largely being replaced by better alternatives in modern formulations. Not recommended in products where nitrosating agents may be present.
