Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Interpretation of results:
other: no oxidising properties
Conclusions:
The test item does not have to be classified as oxidizing solid according to GHS and EC 1272/2008 (CLP-Guideline) Annex 1: 2.14.
Executive summary:

The mean burning times of the test item-to-Kieselguhr ratio 4:1 (57s) and 1:1 (94 s) are lower than the mean burning times of a 4:1 and 1:1 mixture of test item-to-Cellulose (73 s and 156 s, respectively). This shows that the test results with Cellulose are false positive, as the pure test item itself is flammable in mixtures with Kieselguhr. Due to this the test item does not have to be classified as oxidizing solid.
