Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 284-895-5 | CAS number: 84989-06-0 The fraction of tar acids, rich in 2,4- and 2,5-dimethylphenol, recovered by distillation of low-temperature coal tar crude tar acids.
Endpoint summary
Administrative data
Description of key information
The toxicity of m-cresol to lettuce seedlings (Lactuca sativa) was determined according to OECD Guideline 208 in soil. The EC50 was 69 mg/kg soil d.w. after 7 d and 96 mg/kg soil d.w. after 14 d, representing the most sensitive value.
No data on other terrestrial organisms available. Results with Lactuca sativa were used to derive PNEC soil and to conduct risk-assessment.
Additional information
Data on the toxicity to terrestrial plants are available for constituents of Tar acids, Xylenol fraction (CAS 84989-06-0), namely o-, m-, and p-cresol. These data are used to determine the hazard of Tar acids, Xylenol fraction (CAS 84989-06-0) by applying a weight of evidence and an analogue read-across approach. The studies were conducted with seedlings of Lactuca sativa. A worst-case scenario is followed, i.e. for assessment purposes the most sensitive values are considered. For details on the read-across approach please refer to the analogue justification provided in IUCLID section 13.

Data on other terrestrial organisms are not available and endpoints are waived based on the outcome of the risk assessment conducted and the Integrated Testing Strategy for toxicity to sediment (ECHA, 2017; Endpoint specific guidance, Chapter R.7c, Section 7.11.6).
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.
