Sodium 4-[(C16-18-(even numbered)-alkylamino)carbonyl]benzoate

Flammability

Administrative data

Endpoint:

flammable 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:

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. The samples of substance prepared for hazard testing were washed in water and no reaction occurred. The substance is synthesised and only ever expected to reside within a base oil grease matrix. The thickener isolated from base grease exists as a white solid at ambient temperature and pressure which decomposes at 200°C. The self-ignition temperature of the thickener is >400°C, which indicates the substance is not self-heating. Further, the vapour pressure of the substance is predicted to be extremely low (i.e. <<1 Pa at 25°C) using Quantitative Structure Property Relationship (QSPR) models. The substance is therefore not expected to partition from the grease into air and is not expected to be flammable except at very high temperatures. On the basis of the above arguments, coupled with the fact that this substance is only present inside a grease matrix (which implies that this endpoint is considered irrelevant for the assessment of the potential hazard of the registered substance), the requirement to undertake an experimental determination of flammability is waived.
