Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Read-across in accordance with Annex XI, Section 1.5 of Regulation (EC) No. 1907/2006 (REACH) is justified on the following basis:
Polyphosphoric acids, ammonium salt (also known as ammonium polyphosphate) is a mixture of oligomeric species of ammonium phosphate. When analysed, the substance appears to consist mainly of ammonium orthophosphates, ammonium diphosphate and ammonium triphosphate. The proportion of the substance that is an ammonium orthophosphate is ≤ 50% and therefore the data presented in the key study is considered to be relevant to the substance to be registered.
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.
