About

A Girbatol unit feed gas containing butadiene at levels above 0.1% w/w — an EU Annex II CMR Cat 1A material that cannot be used in any cosmetic formulation.

Refinery gas stream fed to the Girbatol (amine) process for sulfur removal, containing residual C2–C4 hydrocarbons including 1,3-butadiene above 0.1% w/w. This conditional trigger places the substance in the CMR Cat 1A prohibited category of EU Regulation 1223/2009 Annex II when applicable, making it illegal as a cosmetic ingredient in EU markets, reflecting its well-established role as a human carcinogen.

Known concerns

  • Contains 1,3-butadiene >0.1% w/w — EU Annex II CMR Cat 1A carcinogen, prohibited in cosmetics
  • Volatile refinery by-product with inhalation and dermal exposure hazards
  • IARC Group 1 human carcinogen — no safe exposure threshold established
