Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 284-892-9 | CAS number: 84989-04-8 The fraction of tar acid rich in 3- and 4-methylphenol, recovered by distillation of low-temperature coal tar crude tar acids.

Description of key information
The log Pow of tar acids, methylphenol fraction is between 1.5-2.5 (read-across).
Key value for chemical safety assessment
Additional information
There is no experimental data of partition coefficient for this substance available.
The value of log Pow is obtained by using read-across estimation based on the available data for cresol isomers (m, p, o-cresol) and two other types of cresol mixtures (mix-cresol CAS 1319 -77 -3 and reaction mass of m- and p-cresol EC no. 906 -151 -7). The key value is taken from the study of reaction mass of m- and p-cresol, which reported a range of log Kow covering all other results.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.
