Description of key information

Additional information

Data available show that PWH/ammonium and PWH/sodium saltsare similar. The two substances are different only in the salification, in fact the paraffinic chain with one sulphonic group, three Cl atoms is always in common.

The read across between PWH/ammonium and PWH/sodium salt is valid, because environmental behaviour is defined by the main component.The read across justification that takes into account the ammonium ion properties is attached on section 13 of the dossier.

The substance is chemically stable, not easily hydrolysable, ready biodegradable, not bioaccumulative. This makes water the preferred compartment for distribution, even if ready biodegradability makes the substance with no concern about persistency
