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 attached) 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 physico-chemical properties is not considered necessary also because the variation in the concentration of the components is not considered to influence the physico-chemical results. Therefore the data of Karanal can be used for Aurawood. In the sections on test substance Karanal is considered the same as Aurawood.
