Description of key information

According to the Wskowwin v. 1.42 model in EPISuite v. 4.1, the test substance has a QSAR- predicted solubility in water of 2E- 12 mg/L. This model estimate is a likely upper bound, because it was computed with a representative structure of the major component (mono- (2- tetradecylnapthalene)) that is expected to have the highest aqueous solubility among the major constituents in the substance.

The extremely low aqueous solubility predicted by the QSAR model is further supported by the results of an attempted aqueous solubility measurement using a slow- stir flask method. This experiment was conducted over the course of an 11 - day stirring period, to ensure that the test substance reached dissolution equilibrium with the aqueous phase. No definitive aqueous solubility result is reported using this method, because the aqueous solubility of the test substance falls below the method detection limit. Based on the method detection limit, the study authors conclude that the aqueous solubility of the test substance is <0.001 mg/L.
