The read across justification with sodium salt and evaluation of impurities document is attached on section 13 of the dossier.
The main constituent -thelong chlorinated paraffinic chain with one sulphonic group- is in common, because raw materials and the production process are the same. Therefore, a read-across approach between the sodium and the ammonium salt can be considered reliable, considering also that the portion of the on ammonium ions is less, ca. 2 %. Impurities have been evaluated.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
