Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
(Q)SAR
Adequacy of study:
key study
Study period:
18 May 2018
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
As the test item (an insoluble UVCB) is not appropriate for testing as such a QSAR has been conducted in order to assess this particular endpoint.
1. SOFTWARE: US EPA On-Line EPI Suite™ model KOCWIN Program (v2.00)
2. MODEL (incl. version number): KOCWIN Program (v2.00)
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL:
Mono:O=C(C)OCC(COC(=O)C)(COC(=O)C)COC(=O)C
