Conclusions:
The mean density of aluminium orthophosphate is 604.0 g/L which corresponds to 604.0 kg/m³.


The study is considered to be adequate and reliable for the purpose of registration under REACH (Regulation (EC) No. 1907/2006).

Description of key information

One key study exists. This study was conclusive, done to a valid guideline (OECD 109) and the study was conducted under standard laboratory conditions. It is therefore scientifically justified for use as a key study under Regulation (EC) No. 1907/2006 (REACH).

Key value for chemical safety assessment
