Description of key information

No particle size distribution necessary due to different uses and manufacturing processes.

Additional information

Glycerides with a melting point below 50 °C are marketed in a semisolid or sticky form and are often melted for further processing and therefore there is no risk for respirable dust or dust explosion in the handling. Glycerides with a melting point above 55 °C are typically marketed as flakes, pastilles or powders. The transformation from liquid to solid is achieved by spray cooling. Therefore the particle size distribution is more a point of the spray cooling conditions and methods than a substance typical property. For standard and coarse powders the mean particle size is > 150 µm the proportion of respirable dust (particles < 10 µm) is negligible (0 - 1.1%). For fine powders the proportion of respirable dust is below 5.5% and is not considered to be significant. The explosion risk posed by glycerides is low.
