Key result

Water solubility:

< 0 g/L

Conc. based on:

test mat.

Temp.:

20.4 °C

pH:

7.9

Details on results:

Test substance was stirred with double distilled water for 6 days at 20.4 ± 0.7°C (nominal concentration was 12 mg/l). The concentration of HATCOL 5150 in the supernatant after two, three and four successive times of centrifugation (3500 g, 5 min. and 20 °C) was 8.91, 8.13 and 7.35 µg/l, respectively. The measured pH was after two, three and four successive times of centrifugation 7.9, 7.8 and 7.9, respectively.
Due to the experience with similar test substances (e.g. Hatcol 3365) it was decided not to perform a main study. Taking all results into account, the water solubility of Hatcol 5150 at 20.4 ± 0.7 °C is reported as < 9x10-6 g/l.
Based on NOTOX experience with similar test substances, a more accurate determination of the water solubility for this kind of extremely apolar test substances (log Pow ≥ 7, see NOTOX project 388057 “Determination of the partition coefficient (N-octanol/water) of Hatcol 5150”) is impossible.

Conclusions:

The water solubility of Hatcol 5150 at 20.4 ± 0.7 °C is < 9x10-6 g/l, the pH was between 7.8-7.9.

Executive summary:

A preliminary test was used to determine the water solubility of HATCOL 5150, which was based on the following guidelines:

OECD guideline for testing of chemicals no. 105: 'Water Solubility', Adopted July 27.1995.

EEC Directive 92/69 EEC, Part A. Methods for the determination of physico-chemical properties, A.6: "Water solubility. EEC Publication no. L383, December 1992.

 

The water solubility of Hatcol 5150 at 20.4 ± 0.7 °C is < 9x10-6 g/l, the pH was between 7.8-7.9.
