- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- GLP compliance:
- no
- Type of method:
- column elution method
- Specific details on test material used for the study:
- hemical name C14 chlorinated N-alkane, 50% Cl (wt.)
Batch/Lot number C14CL50 20160623
Purity 100% (UVCB)

Expiry date 01-12-2018
Solubility in water insoluble in water
Stability not relevant
Storage at ambient temperature in the dark
The concentrations cited in this report refer to the as-received sample of C14 chlorinated N-alkane, 50% Cl (wt.). - Water solubility:
- 6.1 µg/L
- Conc. based on:
- test mat.
- Temp.:
- 18.7 °C
- pH:
- 5.97
- Water solubility:
- >= 4.5 - <= 8.5 µg/L
- Conc. based on:
- test mat.
- Temp.:
- 18.7 °C
- pH:
- 5.97
- Details on results:
- See table for full details.
- Conclusions:
- The average water solubility (Ws) value of a duplicate experiment was 6.1 µg/L with a standard deviation of 29%. The experimental values are in agreement with the range of predicted water solubility by others. The Ws of C14congeners with different chlorine numbers varied between 0.011 and 2.3 µg/L. A quadratic trend between water solubility and chlorine number was found, with a slight increase in water solubility up to 53% Cl.
- Executive summary:
The objective of this study was to experimentally determine the solubility of a C14polychlorinated n-alkane test material with 50% Cl content by weight using OECD Test Guideline 105.The average water solubility (Ws) value of a duplicate experiment was 6.1 µg/L with a standard deviation of 29%. The experimental values are in agreement with the range of predicted water solubility by others. The Ws of C14congeners with different chlorine numbers varied between 0.011 and 2.3 µg/L. A quadratic trend between water solubility and chlorine number was found, with a slight increase in water solubility up to 53% Cl.

Description of key information
The average water solubility (Ws) value of a duplicate experiment was 6.1 µg/L with a standard deviation of 29%. The experimental values are in agreement with the range of predicted water solubility by others. The Ws of C14congeners with different chlorine numbers varied between 0.011 and 2.3 µg/L. A quadratic trend between water solubility and chlorine number was found, with a slight increase in water solubility up to 53% Cl.
Key value for chemical safety assessment
- Water solubility:
- 0.006 mg/L
- at the temperature of:
- 20 °C
