About
Dea-ceteareth-2 Phosphate is a cosmetic ingredient used in product formulations. Note: subject to regulatory restrictions in some markets. Exercise caution due to limited available safety data.
DEA-Ceteareth-2 Phosphate is a phosphate ester of a C16-18 alcohol ethoxylate neutralised with diethanolamine. EU Annex II entry 411 restricts DEA-related compounds in cosmetic products due to the risk of nitrosamine formation (N-nitrosodiethanolamine is a known carcinogen). Products containing this ingredient require careful purity assessment and may be restricted in certain cosmetic applications. The primary concern is not the ingredient itself but residual DEA and resulting nitrosamine contamination.
Known concerns
- Listed under EU Annex II/411 - may contain and release DEA (diethanolamine)
- DEA and DEA-related compounds are restricted due to nitrosamine formation potential
- Potential for residual diethanolamine as impurity
- Possible nitrate/nitrosamine contamination
