Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Categories
- Category name:
- Isomerised olefins including branched, linear, alpha and internal olefins with a range of carbon numbers
Justifications and discussions
- Category definition:
- Isomerised Olefins with a Range of Carbon Numbers
- Category rationale:
- The Isomerised Olefins category covers products which comprise a range of carbon number (generally <10) that may contain several isomers. As the category name implies, these materials are all olefins. These products are a mix of linear/branched and alpha/internal olefins. The category covers a carbon range of C6 to C30. The phys-chem and environmental fate properties of the category members will be similar or if they change they will change in a predictable fashion. For example, the water solubility is expected to decrease as the carbon number range increases. Environmental effects will behave in a similar manner, acting via non-polar narcosis. It is expected that the low water solubility will limit the potential aquatic toxicity of the higher carbon number members. With regard to mammalian endpoints, category members are liquids of moderate to low volatility. Skin contact therefore represents the primary route of exposure with inhalation expected to be only a minor or secondary source of exposure. The category members differ from one-another only in carbon number range. The carbon number, position of the double bond and or presence of branching is not anticipated to have a significant effect on the mammalian toxicity. It can therefore, be assumed that products meeting the applicable domain will behave in a similar manner and that use of read-across is valid.
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.
