- Temp.:
- 20 °C
- pH:
- > 6 - < 7
- Details on results:
- see below
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
- Executive summary:
Water solubility of Octylphenol was determined according to national standard ASTM E 1148 - 02, which is similar to OECD Guideline for Testing of Chemicals No. 105, adopted 27.07.95.
The water solubility was determined to be 7.0 mg/L at a temperature of 20 °C and a pH value of 6 - 7.
