Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
White phosphorus is of limited water solubility (3 mg/L) and the solubilised substance is rapidly oxidised to phosphate. It is well documented that phosphates are critical nutrients required for the growth of algae and other aquatic plants.
Key value for chemical safety assessment
Additional information
No data are available: a waiver is proposed for this endpoint. White phosphorus is of limited water solubility (3 mg/L) and the solubilised substance is rapidly oxidised to phosphate. It is well documented that phosphates are critical nutrients required for the growth of algae and other aquatic plants. Low aquatic concentrations of phosphate resulting from white phosphorus will stimulate the growth of algae. Higher concentrations of phosphate are unlikely to be achieved due to the low water solubility of white phosphorus, but have the potential to cause adverse effects as a consequence of the stimulation of excessive algal growth and subsequent eutrophication.
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.
