Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 266-023-5 | CAS number: 65996-88-5 The distillate from coke oven light oil having an approximate distillation range below 100°C (212°F). Composed primarily of C4 to C6 aliphatic hydrocarbons.

Description of key information
A literature search on available data for the key components was performed with the following results:
* Benzene and Toluene are readily biodegradable but due to some long term toxicity studies with values between 0.1 and 1.0 mg/L it has to be considered as harmful to aquatic organisms which would result in H412 classification
* Carbon Disulphide is readily biodegradable and acute aquatic toxicity values are higher than 1.0 mg/L, therefore no aquatic classification is warranted.
* Limited data on 2 -Pentene were retrieved, however data on 1 -Pentene indicated that the substance was not biodegradable and acute toxicity values could go down to between 1 and 10 mg/L, therefore 2 -Pentene can potentially be toxic to aquatic organisms, resulting in H411 classification.
* Dicyclopentadiene has a harmonised classification as H411. The chronic NOEC for some throphic levels ranges between 0.1 and 1.0 mg/l, confirming the H411 classification. An EC50 of just below 1.0 mg/L (0.823 mg/L) for aquatic invertebrates was also reported, which would in addition require H400 classification, however as other compounds are less toxic to aquatic organisms the overall EC50 for the UVCB is expected to be above 1.0 mg/l confirming the H411 from chronic studies.
* On pentadiene and cyclopentadiene no data were retrieved.
=> Based on the high dicyclopentadiene content and the indications that the other substances present in benzol forerunnings (coal) have similar or lower toxicity a classification as H411 "Toxic to aquatic life with long lasting effects" with chronic NOECs for some throphic levels between 0.1 and 1.0 mg/l, warranting a H411 classification.
Additional information
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.
