Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 266-026-1 | CAS number: 65996-91-0 The distillate from coal tar having an approximate distillation range of 220°C to 450°C (428°F to 842°F). Composed primarily of three to four membered condensed ring aromatic hydrocarbons and other hydrocarbons.
Short-term toxicity to aquatic invertebrates

Description of key information
Three structure related tar oil fractions were tested. Creosote oils, acenaphthene fraction had the lowest EC50/LC50 (2.7 mg/l). This is also the lowest effect level over all trophic levels an will thus be decisive for classification
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 2.7 mg/L
Additional information
Three structure-related tar oils were tested according to OECD guideline 202. Together, These fractions contain the entire range of 2 -5 ring PAH compounds and are therefore considered representative for the aquatic toxicity of distillates (coal tar), upper.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
