Endpoint:
oxidising solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
12/03/2004
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Non-GLP, Guideline study
Qualifier:
according to
Guideline:
other: CLP/GHS testing criteria
Deviations:
no
GLP compliance:
no
Contact with:
powdered cellulose
Duration of test (contact time):
> 9 - < 11 min
Sample tested:
test mixture (not specified)
Parameter:
maximum burning rate
Result:
711 s
Remarks on result:
other: At a dinotefuran : cellulose ratio of 1 : 1, See Table 1 for summary of average rates
Sample tested:
test mixture (not specified)
Parameter:
maximum burning rate
Result:
634 s
Remarks on result:

Remarks:
migrated information
Parameter:
maximum burning rate
Result:
69 s
Remarks on result:
other: At a potassium bromate : cellulose ratio of 2 : 3, See Table 1 for summary of average rates
Sample tested:
reference mixture (not specified)
Parameter:
maximum burning rate
Result:
208 s
Remarks on result:
other: At a potassium bromate : cellulose ratio of 3: 7, See Table 1 for summary of average rates

Table 1: Summary of results

dinotefuran : cellulose

1 : 1

4 : 1

Average burn rate:

10 min. 30 sec

9 min. 52 sec

potassium bromate : cellulose

3 : 2

3 : 7

Average burn rate:

1 min. 7 sec

3 min. 13 sec

Interpretation of results:
GHS criteria not met
Conclusions:
The average burning time of the 4 : 1 and 1 : 1 mixture of dinotefuran : cellulose tested was 9 min. 52 sec and 10 min. 30 sec respectively which is longer than the average burning time of the 3 : 7 mixture of potassium bromate : cellulose; therefore dinotefuran is not classified as an oxidiser.
Endpoint:
oxidising solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
13/10/2000 - 30/05/2001

according to
Guideline:
EU Method A.17 (Oxidising Properties (Solids))
Deviations:
no
GLP compliance:
yes

Remarks on result:
other: Burning rate of dinotefuran:cellulose ratio of 50:50 - faster than the fastest reference mixture.
Sample tested:
test mixture (not specified)
Parameter:
maximum burning rate
Result:
0.49 other: sec/mm
Remarks on result:

test mixture (not specified)
Parameter:
maximum burning rate
Result:
0.43 other: sec/mm
Remarks on result:
other: Burning rate of dinotefuran:cellulose ratio of 70:30 - faster than the fastest reference mixture.
Interpretation of results:
other: oxidising: maximum burning rate equal or higher than reference mixture
Conclusions:
Dinotefuran demonstrated oxidising properties on the basis of test method EC A17.

Description of key information

Key value for chemical safety assessment

Oxidising properties:
oxidising

Additional information

Dinotefuran demonstrates oxidising properties on the basis of test method EC A17. A non-GLP test conducted according to the UN GHS test indicates that dinotefuran does not demonstrate oxidising properties.
