EC number: 268-071-2 | CAS number: 68002-58-4 This substance is identified by SDA Substance Name: C14-C18 dialkyl dimethyl ammonium methyl sulfate and SDA Reporting Number: 17-049-00.
Flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
- Deviations:
- no
- GLP compliance:
- no
- Test procedure:
- burning rate test: preliminary screening test
- Moisture (wt %):
- 0.1
- Remarks on result:
- substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
- Remarks:
- In the preliminary test using a gas flame the sample showed only melting. Therefore no propagation of combustion was given.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Di-C14-18 alkyldimethyl ammonium methosulfate is not flammable.
- Executive summary:
The flammability of Di-C14-18 alkyldimethyl ammonium methosulfate was determined in a UN-N.1 preliminary test. The test item only melted, when a gas flame the was applied.
Therefore, no propagation of combustion was given. The conduct of the definitive test was not required. The test item does not fulfil the criteria for the transport class 4.1 “readily combustible solids”.
