About

A petroleum gas fraction containing butadiene above regulatory limits, classified as a carcinogenic and mutagenic industrial stream not permitted in cosmetics.

This is a C3-4 petroleum gas stream containing >0.1% w/w 1,3-butadiene, a chemical intermediate classified as a Category 1B mutagen (H340) and Category 1 carcinogen (H350) under EU CLP Regulation 1272/2008. The EU Cosmetics Regulation 1223/2009 (Annex II) explicitly prohibits substances classified as CMR Category 1A or 1B from use in cosmetic products, and butadiene-containing streams are covered under this prohibition regardless of concentration processing.
