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
Endpoint:
pyrophoric liquids
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
Endpoint:
flammable solids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid
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
the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture

Description of key information

In accordance with section 1 of REACH Annex XI, the study does not need to be conducted as:
a) No flammability in contact with water: The substance contains no metals or metalloids and therefore will not release flammable gases in contact with water.
b) Experience in production or handling; substance is known to be stable at room temperature.
c) Not a flammable solid: On approach of an ignition source, a short burning may be expected, however, due to the low melting point, a self-sustaining combustion without supply of further energy is to be excluded. Therefore, a classification as flammable solid can be ruled out. The hazard of flammability is then described by the flash point of 81°C.
d) Further, due to the low melting point, self-heating behavior can be excluded.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

o-Cresol is a not readily combustible solid, has no pyrophoric property, does not emit flammable gases in contact with water and is not a flammable solid. Hence no classification according to both Directive 67/548/EEC and GHS (Regulation EC 1272/2008) is required.
