About

A viscous residual stream from vacuum baking operations, containing butadiene above the 0.1% w/w threshold that triggers EU Annex II prohibition for cosmetic ingredients.

Residue stream from the vacuum distillation of visbreaker unit products, containing light hydrocarbon gases including 1,3-butadiene at levels exceeding 0.1% w/w. The presence of butadiene at this concentration classifies this substance as CMR Cat 1A under EU Regulation 1223/2009 Annex II, absolutely prohibiting its use in cosmetic products in EU jurisdictions due to its recognized carcinogenic hazard.

Known concerns

  • Contains 1,3-butadiene >0.1% w/w — EU Annex II CMR Cat 1A carcinogen, banned from cosmetics
  • Complex high-boiling residual matrix with inhalation toxicity concerns
  • IARC Group 1 carcinogen with mutagenic properties — no dermal safe threshold known
