- Specific details on test material used for the study:
- Test Item: Ocimene PQ
Chemical Name: Reaction mass of (Z)-3,7-dimethylocta-1,3,6,-triene and dipentene
Batch No.: A170524D
CAS No.: 338-55-4/138-86-3
Appearance: colourless liquid
Expiry Date: 06/06/19
Purity: 100% - Key result
- Water solubility:
- 8.73 mg/L
- Conc. based on:
- test mat.
- Loading of aqueous phase:
- 125 mg/L
- Incubation duration:
- 72 h
- Temp.:
- 20 °C
- pH:
- > 4.2 - < 4.3
- Details on results:
- The difference between the 24 and 48 hours samples was lower than the 15% limit and between the 48 and 72 hours were out of 15%. The 24 and 48 hours results were averaged to calculate the solubility. The solubility is given as mean±SD.
The water solubility of the test item is 8.73±0.20 mg/L at 20±0.5°C. - Conclusions:
- The water solubility of the test item is 8.73±0.20 mg/L at 20±0.5°C.
- Executive summary:
The water solubility of Ocimene PQ was determined using the flask method and according to to OECD 105 technical guidelines. The water solubility of the test item is 8.73±0.20 mg/L at 20±0.5°C.
