Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 4 April - 17 April 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: OECD test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Deviations:
- yes
- Remarks:
- followed by visual assessment
- Principles of method if other than guideline:
- No definitive determination was feasible by either EC Method A6 or OECD Method 105 because of significant surface active properties in water. At the request of the sponsor, the water solubility was estimated using a visual assessment procedure as detailed below.
- GLP compliance:
- no
- Type of method:
- flask method
- Remarks:
- followed by visual assessment
- Water solubility:
- < 0.51 mg/L
- Temp.:
- 20 °C
- pH:
- >= 5.4 - <= 5.5
- Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
Water solubility was less than 0.51 mg/L. It is highly likely that the sulphated fish oil is insoluble (less than 0.1 mg/L) by OECD test guideline definition. - Executive summary:
No definitive experimental determination of the water solubility was possible as the test item demonstrated significant surface active properties in water. However visually, following a standard procedure and the Tyndall beam technique, the water solubility was determined to be less than 0.51 mg/L of solution at 20 degrees C.
Reference
Beam of light observed, highlighting presence of excess, undissolved test item dispersed throughout the sample in both Flasks #1 and #2. No beam of light observed in the Control flask.
Description of key information
0.51 mg/l
Key value for chemical safety assessment
- Water solubility:
- 0.51 mg/L
- at the temperature of:
- 20 °C
Additional information
No definitive determination was feasible by either EC Method A6 or OECD Method 105 because of significant surface active properties in water. At the request of the sponsor, the water solubility was estimated using a visual assessment procedure -
Tyndall beam technique.
Per the test conducted the substance is slightly soluble (0.1-100 mg/L). Water solubility was less than 0.51 mg/L using a visual assessment method. It is highly likely the substance is insoluble (less than 0.1 mg/L) by OECD test guideline definition.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
