Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

For this endpoint, the read across between PWH/ammonium and PWH/sodium salt is valid, therefore data from this latter dossier can be taken into account.

The read across justification is attached on section 13 of the dossier.

The commercial form of the test item has a boiling point of 118 °C. The dry substance can be expected to have a similar behaviour than Paraffin waxes and Hydrocarbon waxes (C14 -17), chloro, sulfochlorinated, low sulphonated saponified, and then decomposes for temperature > 238°C.

It is supposed that the ammonium salt has the similar phisicochemical property, as reported in the SDS of the registrant.
