A C2-3 petroleum gas stream containing butadiene above the regulatory limit, classified as a prohibited CMR substance in EU cosmetics.

This is a C2-3 hydrocarbon gas stream from petroleum processing containing >0.1% w/w 1,3-butadiene. Butadiene is classified as a Category 1B mutagen (H340) and Category 1 carcinogen (H350) under EU CLP Regulation 1272/2008. The EU Cosmetics Regulation 1223/2009 prohibits CMR Category 1A/1B substances from cosmetic products, and this listing covers all C2-3 gas streams exceeding the 0.1% butadiene threshold.
