Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Other Petroleum Gases - LOA

Justifications and discussions

Category definition:
Category K ‘Other Petroleum Gases’
Category rationale:
The ‘Other Petroleum gases’ category covers hydrocarbon streams containing petroleum gases (alkanes/alkenes) predominantly in the C1-C5 range (with some carbon numbers present at lower levels up to C10) and includes some LPGs. The majority of the members of this category contain <0.1% 1,3-butadiene. Members of this category are products of refining for example distillation of crude oil, catalytic cracking and catalytic reforming, sometimes in association with steam-crackers, or they are produced in association with natural gas processing. Companies importing streams will need to confirm that such streams meet the chemical description and are in domain.
By definition, from the category, these streams have overlapping hydrocarbon compositions, within a defined range, and hence, will have similar properties. It is therefore reasonable to assume that the components of petroleum gases will behave in a reasonably predictable manner, and with respect to phys-chem and environmental fate and effect properties read-across is valid.
With regard to mammalian endpoints, category members may be very volatile liquefied gases or gases with inhalation representing the primary route of exposure. Longer term health effects are not anticipated from the various constituents. The exception to this is the C4 streams which may be classified as a possible carcinogenic hazard (due to the possible presence of 1,3-butadiene at >0.1%).
