Description of key information
A study was performed to determine the oxidising properties of Cobratec 435. The test substance was found to be non-oxidising (EC Method A.17)
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
The test substance/cellulose mixtures did not burn to completion, whilst the barium nitrate reference burned vigorously to completion in 24 seconds.
The following observations were noted for each of the weakly-burning test substance samples:
| Test substance/cellulose ratio | Duration of combustion (seconds) | Observations |
| 2:1 | 2 | Only the tip of the cone burned with a yellow sooty flame, but the mixture remained almost entirely unburned |
| 1:1 | 3 | Only the tip of the cone burned with a yellow sooty flame, but the mixture remained almost entirely unburned |
| 1:2 | 55 | Burned with a yellow sooty flame,but approximately 30% remained unburned |
As none of the test substance/cellulose mixtures burned to completion, Cobratec 435 is considered to be non-oxidising.
Justification for classification or non-classification
The test substance/cellulose mixtures did not burn to completion, whilst the barium nitrate reference burned vigorously to completion in 24 seconds. The test substance was considered to be a non-oxidiser.
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).
