- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- flask method
- Water solubility:
- ca. 0.429 g/L
- Temp.:
- 20 °C
- pH:
- ca. 6.5
- Remarks on result:
- other: The pH of the aqueous sample was determined after 72 hours stirring.
- Details on results:
- The results for the samples taken at 24, 48 and 72 hours are given in Table 1 below.
The maximum difference (MD) of the concentrations determined in the 24, 48 and 72 hour test samples was 15 %. According to the guidelines, the water solubility of the test substance is given as the mean value of the analysed concentrations.
In the pre-treated sample from the bank water mixture a small response was observed, the maximum contribution was 0.06 %, thus neglegible. - Conclusions:
- 2-Ethylhexyl-S-lactate is moderately soluble in water.
- Executive summary:
The flask method was chosen for the determination of the water solubility of PURASOLV®EHL (2 -ethylhexyl-S-lactate). The water solubility of the test substance at 20 °C was 0.429 g/L. The pH of the aqueous sample after 72 hours stirring was 6.5.
