Reference

Endpoint:

water solubility

Type of information:

experimental study

Adequacy of study:

key study

Study period:

1997-06-25 - 1997-07-03

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Remarks:

determination of solubility by visual observation, development of analytical method not possible

Qualifier:

according to guideline

Guideline:

OECD Guideline 105 (Water Solubility)

Qualifier:

according to guideline

Guideline:

EU Method A.6 (Water Solubility)

Principles of method if other than guideline:

Water solubility was determined by visual observation.

GLP compliance:

yes

Type of method:

other: visual observation

Water solubility:

0.92 mg/L

Temp.:

19.5 °C

pH:

6.8

Details on results:

0,92 mg/L at 19,5 °C (+/- 0,5 °C)

After stirring for 8 days, undissolved test substance were observed in both samples. Therefore, the water solubility of the test substance was determined to be < 9.2x10^-4 g/L at 19.5 ± 0.5 °C, by means of visual observations.

Description of key information

<0.92 mg/L at 19.5 ± 0.5 °C, pH = 6.8

Additional information

The water solubility of the substance fatty acids, C16-18 (even numbered) and C18-unsatd., branched and linear, di- and triesters with trimethylolpropane (former CAS 85005 -23 -8) was determined according to OECD guideline 105 / EU method A.6 using the preliminary test (visual observation).
