Oxidising properties
Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising properties
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Remarks:
- The study is well documented and method and results are scientifically valid, althought the measurements were not conducted according to official guidelines and under GLP.
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- other: Solvay internal method PF 30/27 (Determination of oxidizing power through potentiometric titration in neutral Fomblin PFPE fluids.)
- Deviations:
- no
- Principles of method if other than guideline:
- Iodine released from the redox reaction of peroxidic groups of the test item with Sodium Iodide (NaI) is titrated with an aqueous solution of Sodium thiosulfate (0.005 N), in the presence of NOVEC7100® and glacial acetic acid.
The oxidizing power (OP) is expressed in mg of active oxygen released per Kg of test item. - GLP compliance:
- no
- Interpretation of results:
- other: no oxidising properties
- Remarks:
- Migrated information
- Conclusions:
- GALDEN LMW does not possess oxidising properties.
- Executive summary:
The purpose of measurements was to determine the Oxidising Power of GALDEN LMW due to the potential presence of peroxidic groups.
The Oxidising Power (OP) is determined according to the Company internal method PF 30/27.
The principle of the method is to measure the Iodine released from the redox reaction of peroxidic groups of the test item with Sodium Iodide (NaI) through titration with an aqueous solution of Sodium thiosulfate (0.005 N), in the presence of NOVEC7100® and glacial acetic acid.
The oxidizing power (OP) is expressed in mg of active oxygen released per Kg of test item.
The method is applicable to substance with OP greater than 2mgO/kg.
The oxidizing power was determined on six different batches of GALDEN LMW. All the analyzed samples of GALDEN LMW showed an oxidizing power (OP) lower than 2 mgO/kg.
These results show that GALDEN LMW does not possess oxidising properties.
- Endpoint:
- oxidising liquids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied
- the study does not need to be conducted because the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
Basing on the assessment of the chemical structure GALDEN LMW is not expected to be an oxidizing agent and to react exothermically with combustible materials and therefore, according to Column 2 of REACH Annex VII (7.13), conducting an experimental study would be unjustified. In fact, GALDEN LMW contains oxygen and fluorine in its structure but these elements are chemically bonded only to carbon. Furthermore the substance does not contain any of the chemical groups known to confer oxidising properties (attached background material)
Moreover, an experimental determination of the oxidising power due to the potential presence of peroxidic groups as residuals of the manufacturing process was performed.
The determination was conducted according to the Solvay internal method No. PF 30/27, well documented and scientifically valid.
The principle of the method was to measure the Iodine released from the redox reaction of peroxidic groups of the test item with Sodium Iodide (NaI) through titration with an aqueous solution of Sodium thiosulfate (0.005 N), in the presence of NOVEC7100® and glacial acetic acid. The oxidizing power (OP) was expressed in mg of active oxygen released per Kg of test item. Six different batches of GALDEN LMW were analyzed and all of them showed an oxidizing power (OP) lower than 2 mgO/kg. These results confirm that GALDEN LMW does not possess oxidising properties.

Justification for classification or non-classification
GALDEN LMW does not meet the EU criteria to be classified as oxidising liquid.
