Category name:
Butylene Oligomers - LOA

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.
