Description of key information
In line 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 on a waxy solid with determined melting point in the range 29 to 60 °C. This decision is in accordance 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.
Additional information
Particle size influencing toxicological profile is irrelevant because the substance is on the border between the solid and liquid state at ambient temperature. Furthermore, the determined vapour pressures of0.0345 Pa at 25 °C, 0.0985 Pa at 55 °C and 0.891 Pa at 145 °Cindicate that exposure of humans to the test item via the inhalation route is of low concern.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
