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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
The data are derived from Karanal, which is a reaction mass containing several components. Karanal consists of the same components as Aurawood but the concentration of these components are slightly different.
Though ECHA (GB349025-60, 2012, see physico-chemical section) has responded that Karanal is not identical to Aurawood the constituents are the same and may be around the ECHA's threshold when considering Karanal and Aurawood dissimilar.In IFFs view the similarity between these two substances is such that an overall read across justification for fate and distribution is not considered necessary also because the variation in the concentration of the components is not considered to influence the fate and distribution results. Therefore the data of Karanal can be used for Aurawood. In the sections on test substance Karanal is considered the same as Aurawood.
Hydrolysis: The substance is considered to be slightly hydrolysable and most likely restricted to acidic conditions only (Annex XV report).
Biodegradation: In a screening for ready biodegradability test (301F) no significant biodegradation test was seen.
In an OECD TG 309 study the substance is slowly degraded with the DT50 at 22 °C amounting to 56 days (Annex XV, 2015).
Adsorption /desorption: In a GLP-compliant study a log Kocof 3.61 for the substance is reported (Annex XV report, 2015).
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.
