Adsorption / desorption
Administrative data
- 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 physicochemical properties of the substance indicate that it can be expected to have a low potential for adsorption
- 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 component is miscible in water and readily biodegrades.
Titanium salts exist in nature, but have very poor ion exchange capacity with sedioments and clays; instead, insoluble and inert oxides will persist.
Cross-referenceopen allclose all
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 28 days
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Justification for type of information:
- Taken from peer reviewed publication.
Not all method details were reported, but sufficient data to confirm outcome - Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 301 B (Ready Biodegradability: CO2 Evolution Test)
- GLP compliance:
- not specified
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge (adaptation not specified)
- Duration of test (contact time):
- 28 d
- Initial conc.:
- ca. 10 mg/L
- Based on:
- not specified
- Parameter followed for biodegradation estimation:
- CO2 evolution
- Reference substance:
- other: Not specified
- Key result
- Parameter:
- % degradation (CO2 evolution)
- Value:
- ca. 97
- Sampling time:
- 28 d
- Details on results:
- Rate of degradation not reported and 10-day window not assessed.
- Validity criteria fulfilled:
- not specified
- Interpretation of results:
- readily biodegradable, but failing 10-day window
- Conclusions:
- It is possible that the 10-day window is attained, but not specified.
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Justification for type of information:
- Quality control assessment for manufacture in water, resultig in stable clear solution at ca 55% w/w in water (550 g/l)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Principles of method if other than guideline:
- Direct observation in water - similar to screening stage of shake-flask method
- GLP compliance:
- not specified
- Type of method:
- flask method
- Key result
- Water solubility:
- > 550 g/L
- Conc. based on:
- test mat.
- Temp.:
- 20 °C
- pH:
- ca. 1
- Details on results:
- Attempts to removed water lead to increased viscosity and cloudy mixturne. The loss ov clarity may be due to formation of degradation products such as hydroxides and oxides of titanium.
- Conclusions:
- The substance is hightly soluble. It is supplied commercially as a solution in water at 550 g/L and is never isolated from water.
- Executive summary:
The substance is hightly soluble. It is supplied commercially as a solution in water at 550 g/L and is never isolated from water.
