Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 7 to 11 July, 2016.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.21 (Oxidising Properties (Liquids))
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Contact with:
- other: Fibrous cellulose
- Key result
- Sample tested:
- test mixture 1:1
- Parameter:
- mean pressure rise time
- Result:
- 25.53 s
- Sample tested:
- test mixture 1:1
- Remarks:
- 65 % nitric acid: cellulose
- Parameter:
- mean pressure rise time
- Result:
- 4.59 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The sample of Sodium Chlorite Solution 25.6 % (w/w) was found to have a mean pressure rise time greater than that observed for the nitric acid reference sample. The sample was therefore not considered to be an oxidising liquid.
- Executive summary:
A physicochemical test was conducted in order to determine the oxidising properties of an aqueous solution of sodium chlorite 25.6 % w/w. The test was conducted according to the EEC method A.21 under GLP conditions. The test item was found to have a mean pressure rise time greater than that observed for the nitric acid reference sample. The sample was therefore not considered to be an oxidising liquid.
