Tin bis(2-ethylhexanoate)

Flammability

Link to relevant study record(s)

Reference

Reference 1

Endpoint:

pyrophoric liquids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

28 JAN 2010 - 19 APR 2010

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.13 (Pyrophoric Properties of Solids and Liquids)

Principles of method if other than guideline:

no deviations

GLP compliance:

no

Remarks:

This study was conducted in a facility operating to GPL within the UK national GPL monitoring programme, but the study report was not audited by the QA unit. No formal claim for GPL compliance is made for this study.

Test procedure:

ignition time on contact with air

Remarks on result:

no ignition within 5 minutes

No evidence of smoldering, charing, or heating upon contact with dried diatomaceous earth and filter paper.

Interpretation of results:

other: EU GHS criteria not met

Conclusions:

The test material has been determined to be non-pyrophoric as it did not spontaneously ignite (diatomaceous earth, filter paper).

Executive summary:

The pyrophoric properties of Tin bis(2-ethylhexanoate) were investigated according to EU Method A.13, by contacting the substance with dry diatomaceous earth and filter paper matrices for 5 min. As such contact did not result in spontaneous ignition, smoldering, or charing, the substance was concluded to be not pyrophoric. This conclusion is consistent with the absence of known pyrophoric functional groups of the test substance.

Endpoint:

flammable liquids: obsolete as covered by section 'Flash point'

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a liquid

Reason / purpose for cross-reference:

reference to other study

Reference 3

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 organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied

Interpretation of results:

not classified based on GHS criteria

Reference 4

Endpoint:

self-heating substances / mixtures

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 a liquid

the study does not need to be conducted because the substance is completely molten at 160°C

Interpretation of results:

not classified based on GHS criteria

Description of key information

Flammability:

This endpoint is covered for liquid substances by flash-point:

The flash point of Tin bis(2-ethylhexanoate) was determined using the EU Method A.9 (flash point) using a closed-cup apparatus. The temperature associated with flash point was determined for five repeated determinations with fresh portions of the test substance. The lowest temperature at which flash point was reproducibly achieved was 136 °C, which was corrected for deviation of the ambient atmospheric pressure from the standard pressure of 101.325 Pa. The reported flash point, corrected to a pressure of 101.325 Pa, is 137 °C.

Flammability, contact with water:

The study is scientifically not necessary, because the organic substance does not contain metals or metalloids. Also the test material does not contain structural components associated with flammability on contact with water mentioned in the Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, chapter R.7.1.10.3, page 123. Therefore, it can be concluded that the test material exhibit no risk for flammability on contact with water.

Flammability, pyrophoric liquids:

The pyrophoric properties of Tin bis(2-ethylhexanoate) were investigated according to EU Method A.13, by contacting the substance with dry diatomaceous earth and filter paper matrices for 5 min. As such contact did not result in spontaneous ignition, smoldering, or charing, the substance was concluded to be not pyrophoric. This conclusion is consistent with the absence of known pyrophoric functional groups of the test substance.

Flammability, self-heating substances:

The study is scientifically not necessary, because the substance is completely molten at 160 °C. In addition the substance is a liquid.

Key value for chemical safety assessment

Flammability:

non flammable

Justification for classification or non-classification

Flash Point of 137 °C, which is > 93 °C

Auto-ignition temperature > 400 °C

Based on the physical state, the structural elements and the melting point the substance has neither to be classified as flammable in contact with air, nor as pyrophoric solid, nor as self-heating substance.

Taking the above mentioned observations into account, classification according to EU GHS does not apply.
