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

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:

other: At a dinotefuran : cellulose ratio of 4 : 1, See Table 1 for summary of average rates

Sample tested:

reference mixture (not specified)

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.

Type of information:

experimental study

Adequacy of study:

key study

Study period:

13/10/2000 - 30/05/2001

Reliability:

test mixture (not specified)

Parameter:

maximum burning rate

Result:

0.5 other: sec/mm

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:

other: Burning rate of dinotefuran:cellulose ratio of 60:40 - faster than the fastest reference mixture.

Sample tested:

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.

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.
