Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Adsorption / desorption
Administrative data
Link to relevant study record(s)
- Endpoint:
- adsorption / desorption: screening
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Study period:
- From 1997-06-06 to 1997-06-30
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Qualifier:
- according to guideline
- Guideline:
- other: LYMAN, W.J., REEI江， W.F. and ROSENBLATT, D.H. (1 982). Handbook of Chemical Property Estimation Methods. McGraw-Hill.
- Deviations:
- no
- Principles of method if other than guideline:
- The absorption coefficient was estimated through correlation with the water solubility and the n-octanol/water partition coefficient.
- GLP compliance:
- yes
- Key result
- Type:
- log Koc
- Value:
- 2.4 dimensionless
- Remarks on result:
- other:
- Remarks:
- The mean log Koc estimated based on water solubility and partition coefficient.
- Conclusions:
- A mean log10Koc value of 2.4 was estimated for the test item based on water solubility and partition coefficient, which gave an equivalent Koc value of 250.
- Executive summary:
As the test item does not possess a distinct UV /vis spectrum, an experimental determination of the adsorption coefficient is not possible. Values for the adsorption coefficient, Koc, were estimated based on empirical relationships with the water solubility, S, and the partition coefficient, Pow.
The water solubility was determined to be 717 mg/L. An estimated log10Koc value of 2.07 was thus calculated for the test item. The log10Kow was determined to be 2.39. An estimated log10Koc value of 2.68 was thus calculated for the test item.
A mean log10Koc value of 2.4 was thus determined for the test item, which gave an equivalent Koc value of 250.
