- Justification for type of information:
- 1. HYPOTHESIS FOR THE ANALOGUE APPROACH
Both the source and target substances are UVCB alkyldimethyl betaines. The Source substance has an alkyl chain length distribution comprising mainly C12-14, whilst the target chain length distribution is C12-16. It is considered that the presence of a greater percentage of C16 chain lengths in the target will not affect the flammability of the substance compared to the C12-14 source.
2. SOURCE AND TARGET CHEMICAL(S) (INCLUDING INFORMATION ON PURITY AND IMPURITIES)
Source: betaines, C12-14 (even numbered) -alkyldimethyl [EC 931-700-2]
Target: betaines, C12-16 (even numbered) -alkyldimethyl [EC 947-036-1, CAS n/a]. Composition information per section 1.2
3. ANALOGUE APPROACH JUSTIFICATION
The Target substance contains approximately 30-35% of the Source substance (C12-14 betaines) in terms of betaines content, with the remaining 65-70% being the closely related C16 betaine. No data are available for the C16 betaine with regards to flammability. It is condered justified to read across from the C12-14 to the C12-16 betaines as the C16 betaine is not expected to contribute to the potential flammability of the substance.
4. DATA MATRIX
Source: betaines, C12-14 (even numbered) -alkyldimethyl [EC 931-700-2]: Not flammable; EU Method A.10
Target: betaines, C12-16 (even numbered) -alkyldimethyl [EC 947-036-1]: No data - Reason / purpose for cross-reference:
- read-across source
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- 345 s
- Remarks on result:
- other: From the preliminary screening test the sample was seen to burn in a time > 4 minutes and therefore no further testing is required.
Referenceopen allclose all
Results of Preliminary Screening Test Rate of burning (over 200 mm) : 345 sec
From the preliminary screening test the sample was seen to burn in a time > 4 minutes and therefore no further testing is required.
Classification of substance : Not Highly Flammable
Comments: Initially on heating, the sample ignited with an orange flame slowly propagated along the sample train.
Description of key information
The substance is not flammable based on read-across to C12-14 betaines.
The substance is not pyrophoric, and does not release flammable gases in contact with water based on experience in use.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
No studies are available for the substance itself. Data are read across from a study performed according to EU Method A.10 using the analogue substance C12 -14 betaines. In the preliminary screening test the sample was seen to burn in a time > 4 minutes and no further testing was required. The substance was not highly flammable.
Experience in use demonstrates that the substance in not pyrophoric and does not release flammable gases in contact with water.
Justification for classification or non-classification
Based on the results of a study performed using the C12 -14 betaines analogue, the substance is not flammable.
The substance is not pyrophoric, and does not release flammable gases in contact with water based on experience in use. Therefore, classification according to CLP is not required.
