Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

A determination of particle size distribution (granulometry) need not be conducted on substances that are marketed or used in non-solid or non-granular form.  Dimethyl terephthalate is not marketed or used in powder or granular form: it is commonly produced, transported and used in the molten state and as briquettes without respirable dust.  If allowed to cool and solidify, the melt forms a rigid, solid cake.  Milling or grinding would be necessary to transform the cake to a granule or powder (e.g. for testing purposes), but neither process is applied in the commercial production of DMT.
