Applicant's summary and conclusion

Conclusions:

Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
The test material has been determined to have a water solubility fo less than 6.36E-04 g/l at 20 +/- 0.5°C.

Executive summary:

Method

The determination was carried out using a procedure based on the flask method, Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.

The calculation was performed using computer based specialist estimation software WSKOW, version 1.41, © 2000, U.S. Environmental Protection Agency

Results

Visual estimation

Excess test material remained in the sample solution.

Overall: Water solubility less than 6.36 x 10^-4g/l

Atom/Fragment Contribution

Using the chemical estimation software, the test material has been predicted to have water solubility values of:

Component	WSKOW Water Solubility (mg/l)
Lithium salt of oleic acid	6.458
Lithium salt of linoleic acid	10.12

Conclusion.

Using a visual estimation technique based on Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995, the test material has been determined to have a water solubility of less than 6.36 x 10^-4 g/l at 20.0 ± 0.5°C. A calculated value of water solubility gave results of:

 

Component	WSKOW Water Solubility (mg/l)
Lithium salt of oleic acid	6.458
Lithium salt of linoleic acid	10.12
