EC number: 919-164-8 | CAS number: -
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
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Justification for type of information:
- The substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. However, this endpoint is characterised using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see Product Library in PETRORISK spreadsheet attached below in Attached Justification as well as in IUCLID section 13)
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- Model(s) used: PETRORISK v7.04 that incorporates the updated TLM that resulted from the 2014 – 2016 Concawe projects performed in response to an ECHA compliance check
- GLP compliance:
- not specified
- Type of method:
- other: PETRORISK
- Key result
- Type:
- log Koc
- Value:
- ca. 3.5 dimensionless
- Remarks on result:
- other:
- Remarks:
- pH and temperature are not calculated
- Conclusions:
- Adsorption of Hydrocarbons, C10 -C13, n-alkanes, isoalkanes, cyclics, aromatics (2 -25%) calculated in PETRORISK is ca. 3.50.
- Executive summary:
Substance is a hydrocarbon UVCB and the constituent hydrocarbons will exhibit a wide range of water solubility. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance as the composition of the total dissolved hydrocarbons will be different from the composition of the parent substance. However, this endpoint is characterized using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see Product Library in PETRORISK spreadsheet attached in section 13 of the dossier).
Adsorption of Hydrocarbons, C10 -C13, n-alkanes, isoalkanes, cyclics, aromatics (2 -25%) calculated in PETRORISK is ca. 3.50.
