Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: the solubilty of UVCB is the limiting factor for the logPow determination
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 117 (Partition Coefficient (n-octanol / water), HPLC Method)
- GLP compliance:
- not specified
- Type of method:
- HPLC method
- Partition coefficient type:
- octanol-water
- Key result
- Type:
- log Pow
- Partition coefficient:
- < 1.9
- Remarks on result:
- other: < 5 % of the UVCB test item, mainly associated to disulfonated carbonic acids
- Key result
- Type:
- log Pow
- Partition coefficient:
- >= 1.9 - <= 5.1
- Remarks on result:
- other: aprox. 25% of the UVCB test item, associated to sulfoacids of carbonic acids and dibutylamides
- Key result
- Type:
- log Pow
- Partition coefficient:
- > 5.1
- Remarks on result:
- other: 10-15% of the UVCB test item, associated to carbonic acids and dibutylamides
- Conclusions:
- Below 5 % of the test item has a log Pow < 1.9 (disulfonated carbonic acids), approximately 25 % has a log Pow between >= 1.9 and <= 5.1 (sulfoacids of carbonic acids and dibutylamides) and 10-15 % has a log Pow >= 5.1 (carbonic acids and dibutylamides)
- Executive summary:
A study was conducting according to OECD test guideline 117 to determine the logPow of the test item. Therefore, the HPLC method was used.
The logPow of < 5 % of the UVCB test item, mainly associated to disulfonated carbonic acids is < 1.9.
The logPow of aprox. 25% of the UVCB test item, associated to sulfoacids of carbonic acids and dibutylamides is >= 1.9 <= 5.1
The logPow of 10-15% of the UVCB test item, associated to carbonic acids and dibutylamides is > 5.1.
The estimated key value (log Pow 2.99) for chemical safety assessment is based on combination of worst case assumption of water/n-octanol solubilities and HPLC-chromatogramm of the the target substance of the UVCB (N,N-dibuty(sulphonatooxy)octadecanamidate and sodium sulphooctadecanoate) according oecd test guideline 117.
