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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: - | CAS number: -
Adsorption / desorption
Administrative data
Link to relevant study record(s)
- Endpoint:
- adsorption / desorption
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Study period:
- From 1996-01-04 to 1996-05-09
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Remarks:
- LYMAN, W.J., REEHL, W.F. and ROSENBLATT, D.H. (1982). Handbook of Chemical Property Estimation Methods. McGraw-Hill.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- No experimental determination was possible due to lack of a suitable analytical method. Therefore log Koc was estimated by correlation with the n-octanol/water partition coefficient.
- GLP compliance:
- yes
- Specific details on test material used for the study:
- - Substance type: Organic
- Physical state: Solid
- Composition of test material, percentage of components: relative proportions components 1, 2 and 3 are 100:60:40 - Type:
- Koc
- Value:
- > 10 000 L/kg
- Remarks on result:
- other: estimated by correlation with the n-octanol/water partition coefficient
- Type:
- log Koc
- Value:
- > 4 L/kg
- Remarks on result:
- other: estimated by correlation with the n-octanol/water partition coefficient
- Conclusions:
- Log10Koc >4 for the 3 main components, Equivalent Koc >1E+04
- Executive summary:
No experimental determination was possible due to lack of a suitable analytical method. Therefore log Koc was estimated by correlation with the n-octanol/water partition coefficient.
Log10Koc was estimated to be >4 for the 3 main components, Equivalent Koc >1 E+04.
Reference
From the Kow values estimated for the three main components of test item, the following estimated Koc values were obtained: Log10Koc>4 for the 3 main components
Equivalent Koc>1 E+04
Description of key information
Conducted using a recognised calculation method as described in:
LYMAN, W.J., REEHL, W.F. and ROSENBLATT, D.H. (1982). Handbook of Chemical Property Estimation Methods. McGraw-Hill.
Log10Koc was estimated to be >4 for the 3 main components, Equivalent Koc >1 E+04.
Key value for chemical safety assessment
- Koc at 20 °C:
- 10 000
Additional information
From the Kow values estimated for the three main components of test item, the following estimated Koc values were obtained: Log10Koc>4 for the 3 main components. Equivalent Koc>1 E+04.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
