Toxicity to aquatic algae and cyanobacteria
Administrative data
- Endpoint:
- toxicity to aquatic algae and cyanobacteria
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
The study is not technically feasible as the substance is a gas insoluble in water. Furthermore, the Log Kow <3 indicates that the substance is unlikely to cross biological membranes. Consequently, the study is technically not feasible and scientifically not necessary.

- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Log Kow (Log Pow):
- 1.97
The calculated value of 1.97 is used as key value.
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- No information provided
- GLP compliance:
- not specified
- Type of method:
- other: no information provided
- Key result
- Water solubility:
- 0.024 mg/L
- Temp.:
- 25 °C
- pH:
- 7
- Conclusions:
- The water solubility of octafluorocyclobutane is 0.024 mg/L at 25°C.
- Executive summary:
Octafluorocyclobutane is a gaz with very low solubility value (0.024 mg/L at 25°C) and thus can be considered as insoluble (<0.1mg/L).
