Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

non flammable
The substance has no pyrophoric properties and does not liberate flammable gases on contact with water.

Key value for chemical safety assessment

non flammable

Additional information

solid: not highly flammable. Non flammable solid. Flammability derived from screening test.

Based on chemical structure pyrophoric properties and flammability in contact with water are not to be expected.

The flammability of DCDPS was investigated under GLP and a non-GLP according to the EU TGD A.10 . Based on the results of both studies, DCDPS would not be considered as “highly flammable” according to the criteria of the guideline.

It is considered needless to perform another experimental approach employing Method UN N.1. The differences in the test designs are irrelevant, since all attempts to ignite of DCDPS failed.

Justification for classification or non-classification

No need for classification according to EU legislation and CLP.
