Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 28th March to 5th May 1995
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.6 (Water Solubility)
- Deviations:
- yes
- Remarks:
- 14C-radiolabelled material was used; pH not measured; no preliminary study.
- GLP compliance:
- not specified
- Type of method:
- column elution method
- Water solubility:
- 38 µg/L
- Temp.:
- 20 °C
- pH:
- 7
- Remarks on result:
- other: No pH check due to system design
- Details on results:
- Two assays were conducted:
Assay 1:
Temperature: 19.9 - 21.1°C
Water solubility: 46.3 +/- 0.56 µg/L
Time to attain saturation plateau = 1230 hours
Assay 2:
Temperature: 19.5 - 21.0°C
Water solubility: 64.9 +/- 1.13 µg/L
Time to attain saturation plateau = 1290 hours
The difference between assay results was 17.5%. Therefore, assays agreed with a repeatability of less than 30% - Conclusions:
- Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
The substance was found to be practically insoluble in water. The water solubility was found to be 38 µg/L. - Executive summary:
The water solubility of a mixture of benzyltoluene and dibenzyltoluene was determined according to EU Method A.6 (column elution method) using radioactive material. It was found to be 56 µg/L. As another study as shown that water solubility of dibenzyltoluene is 18 µg/L, it can be concluded that solubility of benzyltoluene in pure water is 38 µg/L (at 20°C).
Reference
Description of key information
A good quality study shows that solubility of benzyltoluene in pure water is 38 µg/L at 20°C
Key value for chemical safety assessment
- Water solubility:
- 0.038 mg/L
- at the temperature of:
- 20 °C
Additional information
The key study has been carried out (according to EC method A.6) on a mixture of benzyltoluene (3/4) and dibenzyltoluene (1/4). The measured solubility was 56 µg/L. As it is known from another experiment carried out in same conditions that solubility of pure dibenzyltoluene was 18 µg/L, it can be concluded that 38 µg/L on the present study can be attributed to benzyltoluene.
