  • Ethanolamine (MEA/DEA/TEA)
  • Expert review pending
High concern Level 3 of 4 How concern levels work

A regulatory warning or restriction somewhere, or strong evidence of harm at typical intake. The concern level sets how many points cocamide DEA costs on a product’s receipt.

What the evidence says

  • IARC Group 2B (possibly carcinogenic)Strong evidence

    IARC classifies diethanolamine and coconut oil diethanolamine condensate as Group 2B; the NTP study did not establish a link to cancer in humans. [1][2]

  • Warning label requiredRegulatory

    Listed under California Proposition 65 (cancer, 2012). [3]

  • Nitrosamine formation (cosmetics)Regulatory

    Secondary alkanolamines can form nitrosamines; the EU prohibits them in cosmetics and restricts the amides. [4]

Evidence tiers say how sure the evidence is, separately from how much it matters. About evidence tiers.
