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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Thermal sensitivity (effect of a flame) Tests with the 6.0 mm diameter orifice plate on the Centella Asiatica Dried Extract sample are described below:
- widening of the flame from around 38 seconds, with white smokes and spurts (start of the culmination phase;
- end of the culmination phase at around 370 seconds;
- end of the of any event after around 600 seconds.
Tests with the 2.0 mm diameter orifice plate on the Centella Asiatica Dried Extract sample gave the same results described above except for a more intense flame. No one of the six tests performed (three with the 6.0 mm orifice plate and three with the 2.0 orefice plate) produced the fragmentation of the steel tube containing the Centella Asiatica Dried Extract sample.
Mechanical sensitivity (shock) Explosions did not occur (bursting into flame and/ or a report is equivalent to explosion) in anyone of the six tests performed with impact energy of 40 J on a sample of Centella Asiatica Dried Extract. Then the sample of Centella Asiatica Dried Extract resulted not sensitive to shocking.
Mechanical sensitivity (friction) Explosions did not occur (crepitation and/or a report or bursting into flame are equivalent to explosion) in anyone of the six tests performed with whit a loading of 360 N on a sample of Centella Asiatica Dried Extract.
Then the Centella Asiatica Dried Extract resulted not explosive.

Justification for classification or non-classification
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.
