Water solubility

Link to relevant study record(s)

Reference

Endpoint:

water solubility

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: The reliability rating was 2 because the water solubility was determined using the water solubility-partition coefficient correlation method of Yalkowsky et al. (1983). The partition coefficient was measured experimentally.

Qualifier:

according to guideline

Guideline:

other: calculated using method of Yalkowsky and McKay

Principles of method if other than guideline:

The water solubility could not be reliably measured using the OECD 105 flask method due to emulsion formation difficulties. Instead, water solubility of the substance was estimated from its experimentally determined octanol-water partition coefficient values using the water solubility-partition coefficient correlation method of Yalkowsky et al. (1983).

GLP compliance:

no

Type of method:

other: Water solubility-partition coefficient correlation method of Yalkowsky et al (1983)

Water solubility:

> 0 - < 0.001 mg/L

Temp.:

25 °C

Remarks on result:

other: the water solubility was estimated to be 0.000026 to 0.00068 mg/L at 25 °C using the water solubility-partition coefficient correlation of Yalkowsky et al (1983)

Conclusions:

Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
The water solubility of the test substance was estimated to be 0.000026 to 0.00068 mg/L at 25 °C using the water solubility-partition coefficient correlation method of Yalkowsky et al. (1983). Experimentally measured log partition coefficient values of 9.5 to 11 were used in the calculation equation. Attempts to measure the water solubility of the test substance using the OECD 105 flask method turned out to be unreliable due to emulsion formation difficulties.

Executive summary:

The water solubility of the test substance was estimated to be 0.000026 to 0.00068 mg/L at 25 °C using the water solubility-partition coefficient correlation method of Yalkowsky et al. (1983). Experimentally measured log partition coefficient (log Kow) values of 9.5 to 11 were used in the calculations.
