Description of key information
The estimated water solubility of Procrylat is 0.072 µg/L (WATERNT v1.01, as in EPISUITE v4.11).
Key value for chemical safety assessment
Additional information
Procrylat is of low water solubility. In a supporting study done as a modified column elution experiment under OECD TG105, Procrylat was not present above the limit of quantitation (LOQ) as injected (LOQ, 0.900 µg/L) and was subject to sorbtion to the sampling equipment used in the test. Given experimental LOQ, dilution factor, estimated sorption potential and experimental variance, an upper water solubility limit of <16.8 µg/L was reported. QSAR modeling was done to assess actual limit of water solubility. The model chosen, WATERNT v.1.01, is a valid model and Procrylat is within its applicability domain. The modeled solubility is therefore accepted as the key result. A third report, <0.1 % v/v, could not be assigned as to its reliability and is not considered further.
