About

A hydroxyamine (alkanolamine) restricted under EU Annex II, representing a category of compounds with significant toxicity concerns.

Butylethanolamine is listed on EU Annex II under reference II/411, indicating it is prohibited for use in cosmetic products within the EU under Regulation (EC) No 1223/2009. The combination of both hydroxyl and amine functional groups in a butyl-substituted structure raises concerns for acute toxicity, skin penetration, and nitrosamine formation. Alkanolamines as a class have been subject to regulatory restriction due to their potential to form nitrosamines, which are known carcinogens, during storage or use.

Known concerns

  • EU Annex II restricted (II/411) - PROHIBITED in cosmetic products
  • Potential nitrosamine formation during storage or use
  • Skin penetration and acute toxicity concerns
