Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance and its relevant degradation products decompose rapidly

Additional information

Since the substance rapidly hydrolyses in water, its environmental fate and distribution will be based on its primary degradate, isophthalic acid.

The relevant regression equation within KOCWIN v2.0 is: log Koc = 0.55313 log Kow + 0.9251 + correction factors (where n= 447, r2 = 0.855). This QSAR is preferred for use since an experimental value of logKow was available for IPA, logKow =1.66 (neutral form), and a correction factor is applied to account for IPA being an acid and therefore able to ionise. Since IPA lies within the domain of the QSAR as defined by the logKow and MW ranges, its prediction is considered valid for use.
