Additional information

Glycols with a melting point above 40 °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.
