Sodium O,O-diisobutyl dithiophosphate

Flammability

Link to relevant study record(s)

Reference

Reference 1

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

Reference 2

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 substance is known to be soluble in water to form a stable mixture

Reference 3

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2012-06-12 - 2012-07-02

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

GLP compliance:

no

Specific details on test material used for the study:

The production method yields the substance in an approximately 50% aqueous solution with a content of sodium hydroxide. A sample of this has been dehydrated in order to perform the test.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Not highly flammable

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 completely molten at 160°C

Description of key information

Flammability

EU method A.10: The test item is not considered a flammable solid. Thus test item has not to be classified according to EU GHS criteria.

Flammability_self heating substances

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

Flammability, contact with water

The study is scientifically not necessary, because the substance is known to be soluble in water to form a stable mixture.

Flammability, pyrophoric solids

The study is scientifically not necessary, because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and the test material does not contain structural components associated with pyrophoricity 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 pyrophoricity.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Dehydrated sample of IBP1-Na (produced by adding aqueous NaOH to IBP-1)

Justification for classification or non-classification

The test substance is not a readily combustible solid in the sense of Regulation (EC) No. 440/2008, Method A.10 and Regulation (EC) No. 1272/2008.

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.
