Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In accordance with column 2 of REACH Regulation (EC) No. 1907/2006, Annex IX, section 9.4, the studies on terrestrial organisms do not need to be conducted as neither direct nor indirect exposure of the soil compartment is expected with the "reaction product of oleyl alcohol with polyphosphoric acid". The exposure via air is considered to be negligible, because the vapour pressure of the "reaction product of oleyl alcohol with polyphosphoric acid" is very low.
A study on activated sludge showed signs of respiratory inhibition. However, the NOEC is below the limit of water solubility. In summary, due to low bioavailability caused by low water solubility it is concluded that tests on terrestrial organisms will not provide additional information for the ecotoxicological risk assessment. Moreover, the exposure via different pathways is limited. Consequently the terrestrial studies are waived.

Additional information
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.
