Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
According to regulation (EC) No 1907/2006, Annex XI, paragraph 1.5., substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or "category" of substances. Environmental effects or environmental fate may be predicted from data for reference substance(s) within the group by interpolation to other substances in the group (read-across approach).
The substance (EC No 238 -063 -3) is the sodium salt of the read-across substance (EC No 202 -180 -8, naphthoic acid). Under environmental conditions the sodium salt will dissociate into the sodium cation and the organic acid. Therefore it is acceptable to predict the environmental behaviour from data of the free acid.
The test substanace is not readily biodegradable and does not bioaccumulate.
In a modified MITI-test (I) the read-across substance (EC No 202 -180 -8) was not readily biodegradable. After 14 days 1.3 % of the test substance biodegraded. The potential to bioaccumulate was investigated in a bioconcentration study with the carp (Cyprinus carpio) as test organism with the read-across substance (EC No 202 -180 -8). At the end of a 6 -week exposure period, the measured BCF was below 4.
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.
