Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Justifications and discussions
- Category definition:
- Butylene Oligomers
- Category rationale:
- Butylene Oligomers category contains hydrocarbon streams obtained by the oligomerisation of butylenes. The substances within this category consist predominantly of C4, C8, C12, C16 and/or C20 hydrocarbons. The category stream components boil between 100 and 350 °C and the streams contain less than 0.1% butadiene. The physico-chemical properties associated with these types of UVCBs indicated that they comprise a category based on the range of boiling points (from 100°C to 350°C) and will have similar behaviour in the environment. The estimated log Kow ranges from 4.12-9.91 and the streams in this category are considered to be readily biodegradable. The mammalian toxicity information and environmental assessment also indicated that the streams in this category exert similar effects.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
