Description of key information

Granulometry was not investigated because the test item is a low melting point solid with determined melting temperature of 30 to 47°C at 102 kPa. Particle size influencing toxicological profile is irrelevant because the substance is on the border between the solid and liquid state at ambient temperature.

Additional information

In accordance with REACH Annex XI, a granulometry determination has been omitted because properties of the substance mean it is technically not possible to conduct the study. This decision is in line with OECD guideline 110 where melting point is noted as guidance information because that physical property must be available in order to confirm the solid nature of any substance being considered for testing.
