Cyclopentadecanone

Flammability

Link to relevant study record(s)

Reference

Reference 1

Endpoint:

substances / mixtures which in contact with water emit flammable gases

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING

The data waiving was based on the expert statement in the study report.
The molecular structure of the test item does not contain groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas. Moreover the test item was dissolved in water during the determination of the water solubility. It demonstrated that the test item does not ignite spontaneously in contact with water. In conclusion, Cyclopentadecanone is considered ‘not highly flammable’ in contact with water.

Reason / purpose for cross-reference:

data waiving: supporting information

Qualifier:

according to guideline

Guideline:

other: UN ST/SG/AC.10/11: Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Appendix 6 "Screening procedures"

Version / remarks:

Rev. 6 (2015)

Deviations:

no

GLP compliance:

yes

Interpretation of results:

other: not classified under CLP/GHS

Conclusions:

The substance, in contact with water, does not emit flammable gases.

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

12 December 2015 - 21 April 2016

Reliability:

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Version / remarks:

2008

Deviations:

no

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)

Version / remarks:

Rev. 5 (2009)

Deviations:

no

GLP compliance:

yes

Key result

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

In contact with the flame of the gas burner the test substance melted and turned into a colourless white residue. Grey smoke was observed. After removal of the ignition source, no propagation of

combustion of the test substance was observed.

Interpretation of results:

other: not classified based on GHS / CLP criteria

Conclusions:

The substance was determined to be not highly flammable.

Executive summary:

The flammability of the solid substance was determined in a GLP study according to EC A.10 and UN Test N.1. In the preliminary screening test, the substance did not ignite. No propagation of combustion either by burning with flame or smouldering along 200 mm of the train was observed within the test period. The substance was therefore determined to be not highly flammable (not readily combustible).

Reference 3

Endpoint:

pyrophoric solids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING

The data waiving was based on the expert statement in the study report.
The molecular structure of the test item does not contain groups that might lead to ignition in contact with air. Moreover the test item was handled under normal laboratory conditions during the determination of physico-chemical properties (e.g. flammability test). It demonstrated that the test item does not ignite in contact with air.
In conclusion, Cyclopentadecanone has no pyrophoric properties.

Reason / purpose for cross-reference:

data waiving: supporting information

Qualifier:

according to guideline

Guideline:

other: UN ST/SG/AC.10/11: Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Appendix 6 "Screening procedures"

Version / remarks:

Rev. 5 (2009)

Deviations:

no

GLP compliance:

yes

Interpretation of results:

other: not classified under CLP/GHS

Conclusions:

The substance is not a pyrophoric solid.

Description of key information

Not highly flammable/not readily combustible (EC A.10 and UN Test N.1: preliminary screening test).

No pyrophoric properties (based on experience in handling and on structural features (UN-MTC Appendix 6)).

Not highly flammable in contact with water (based on experience in handling and on structural features (UN-MTC Appendix 6)).

Key value for chemical safety assessment

Flammability:

non flammable

Justification for classification or non-classification

- Because not highly flammable/not readily combustible in the EC A.10/UN N.1 test, no classification is required for the CLP hazard 'Flammable solid'.

- No classification is required for the CLP hazard 'Pyrophoric solids' or 'Substances which in contact with water emits flammable gases'.

- Because of the melting temperature < 160°C, the substance need not be considered for CLP classification in the 'Self-heating substances' class.
