- Type of method:
- flask method
- Water solubility:
- 84.5 mg/L
- Temp.:
- 20 °C
- pH:
- 6.4
- Remarks on result:
- other: Mean values for 24 -72 hours, deviation (24 - 72 hours) 8 %. Temperature 20 ± 0.5 ºC.
- Details on results:
- Tyndall Effect was negative for all samples.
The validity criteria were met:
The concentrations did not differ by more than 15 %.
The temperature were kept constant at ± 0.5 ºC. - Conclusions:
- Interpretation of results: slightly soluble (0.1-100 mg/L)
The water solubility of 1,3-dimethyl-3-phenylbutyl acetate was determined to be 84.5 mg/L at 20.0 ± 0.5 °C and pH 6.4. - Executive summary:
The water solubility of 1,3-dimethyl-3-phenylbutyl acetate was determined to be 84.5 mg/L at 20.0 ± 0.5 °C and pH 6.4. The water solubility of the test item was determined in a GLP study (2015) following OECD guideline 105. The study is considered reliable and relevant for use for this endpoint.
