Additional information

Due to the low water solubility and polymeric nature of the test substance (Formaldehyde UVCB Product), experimental methods were deemed to be unsuitable as the expected test substance concentrations in the resultant water layers could not be accurately assessed.

Determination of individual solubilities was performed and these results were used to estimate the Partition Coefficient.
