- Details on test material:
- The 8-2 Telomer B alcohol (CAS number 678-39-7; CAS name: 1-decanol, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,-10,10,10-heptadecafluoro) was obtained from Clariant (Germany) and was shown to be 99.2% pure via gas chromatography.
The major impurity (0.8% by area) was tentatively identified as C7F15CF=CHCH2OH based on the mass spectral fragmentation pattern.
Melting point (Clariant): 48-50 °C. All solutions were prepared in ultrapure water.

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The 8-2 Telomer B alcohol which is the main constituant of the substance has a very low water solubility (137 ppb at 25°C) - Executive summary:
The solubility in water at 12 °C is 134 ppb ((29 ppb) (134µg/L), 137 ppb ((53 ppb) at 25 °C, 318 ppb ((176 ppb) at 37 °C, and 225 ppb ((51 ppb) at 60 °C. Varying pH from 3 to 11 had little or no impact on the solubility measurement.
