Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
Water solubility: 2.0 mg/L at 25 °C, pH 6 - 7 - Executive summary:
Water solubility of Dodecylphenol 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 2.0 mg/L at a temperature of 25 °C and a pH value of 6 - 7.
