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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Adsorption / desorption
Administrative data
Link to relevant study record(s)
- Endpoint:
- adsorption / desorption: screening
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance and its relevant degradation products decompose rapidly
- Justification for type of information:
- The organic components are considered to be readily biodegradable and highly soluble in water, but titanium dioxide is inorganic and the end point does not apply. titanium dioxide will collect in soil and sediment, but there is no evidence of any biological impact.
- Endpoint:
- adsorption / desorption: screening
- Type of information:
- (Q)SAR
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Estimation of the organic carbon-normalized sorption coefficient for soil and sediment
