Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
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

Remarks:
pH and temperature are not calculated
Conclusions:
Adsorption calculated in PETRORISK is ca. 5.07 dimensionless.
Executive summary:

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 in the RSS justification as well as in IUCLID section 13).

 

Adsorption calculated in PETRORISK is ca. 5.07 dimensionless.

Description of key information

Hydrocarbons, C4, 1,3-butadiene-free, polymd., tetraisobutylene fraction, hydrogenated  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 in the RSS justification as well as in IUCLID section 13).

 

Adsorption calculated in PETRORISK is ca. 5.07 dimensionless.
