About

A DEA-salt of an ethoxylated oleyl alcohol phosphate similar to DEA-OLETH-5 Phosphate, restricted in the EU due to diethanolamine content and nitrosamine formation potential in cosmetic formulations.

Bis(2-hydroxyethyl)ammonium salt of ethoxylated oleyl alcohol phosphate ester (10 mol EO average). Listed in EU Regulation (EC) No 1223/2009 Annex II under reference II/411, prohibiting cosmetic use. Like the 5 mol EO analogue, the DEA component presents a nitrosation risk, forming NDELA. The higher EO chain does not mitigate the regulatory restriction driven by the DEA moiety.

Known concerns

  • EU Annex II restricted — prohibited in cosmetic products
  • DEA content may form carcinogenic nitrosamines
  • Nitrosation risk is independent of EO chain length
