Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The fish bioconcentration test as as described in OECD Guideline  No. 305 was replaced by a theoretical based evaluation using QSAR model prediction 
methods, because reaction product of oleyl alcohol with polyphosphoric acid is highly insoluble in water. 
Evaluation of bioaccumulation potential
For substances that have exceptional properties (e.g. very low water solubility) and/or which consist of multiple constituents, test guidelines used to 
determine bioaccumulation, in the PBT/vPvB assessment may not be directly applicable. Instead specific assessment strategies may be warranted, such as QSAR based screening methods. When using QSAR model prediction methods for identifying the bioaccumulation potential of the UVCB test substance “Reaction product of oleyl alcohol with polyphosphoric acid”, the substance was considered to be non-bioaccumulative. All components of the UVCB substance 
“Reaction product of oleyl alcohol with polyphosphoric acid” had bioconcentration factors smaller than 2000 L/kg.
