Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The vapour pressure of STPP is negligible, the IUCLID chemical data sheet from the EINECS register indicates a vapour pressure of 0.1 hPa (10Pa). The Henrys law constant is calculated to be 0.03 Pa·m3·mol-1. Atmospheric exposure is not therefore anticipated.
STPP and its soluble complex salts are not expected to adsorb highly onto the solid particles of the aquatic environment, due to their solubility.
In soils, it is expected that STPP will hydrolyse and be bio-assimilated via the same mechanisms in the aquatic environment.
The formation of complex insoluble species is likely to occur in soils. Thus it is expected that STPP may also be transformed in soils to insoluble forms which will remain trapped in soils.
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.
