Key result
Test procedure:
other: Evaluation of chemical structure
Remarks on result:
other: resulted in no groups which might lead to ignition

A test substance is considered highly flammable when it ignites spontaneously in contact with water, or evolves a flammable gas at a minimum rate of ≥ 1 litre/kg of the substance per hour.

None of the components of the test substance does contain groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas. The molecular structures of impurities at =< 1% were not taken into account.

 

In conclusion, Decanoic acid, mixed esters with heptanoic acid, octanoic acid and trimethylolpropane is considered ‘not highly flammable’ in contact with water.

Interpretation of results:
not classified based on GHS criteria
Conclusions:

Key result
Test procedure:

Remarks on result:
other: No groups found which may result in ingnition in contact with air.

A test substance is considered pyrophoric when it ignites within five minutes of coming in contact with air.

None of the components of the test substance does contain groups that might lead to ignition in contact with air. Moreover the test substance was handled under normal laboratory conditions during this project. It demonstrated that the test substance does not ignite in contact with air at room temperature. The molecular structures of impurities at =< 1% were not taken into account.

 

In conclusion, Decanoic acid, mixed esters with heptanoic acid, octanoic acid and dimethylolpropane has no pyrophoric properties.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
In conclusion, Decanoic acid, mixed esters with heptanoic acid, octanoic acid and dimethylolpropane has no pyrophoric properties.

Description of key information

Regarding flammability (contact with water) and pyrophoric properties, a statement based on the molecular structure rather than a full study was considered sufficient to cover these endpoints. The substance is non flammable.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Flammability in contact with water

 

The structural features of the substance were evaluated and it was concluded that none of the components contains groups that might lead to the evolution of a dangerous amount of flammable gas when coming into contact with water or damp air. No metals, transition metals, boron or silicon are present.

 

In conclusion, the test substance is not highly flammable in contact with water or damp air.

 

Pyrophoric properties

 

The structural features of the components of the substance were evaluated and it was concluded that none of the components contain any chemical groups that might lead to spontaneous ignition a short time after coming into contact with air. Furthermore, experience from using this substance as a lubricant shows that the test substance does not ignite spontaneously after coming in contact with air at room temperature.

Justification for classification or non-classification

Based on the above mentioned evaluation, classification according to the CLP Regulation (EC) 1272/2008 and the Dangerous Substance Directive 67/548/EC is not necessary.
