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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
No autoignition up to the maximum test temperature of 401°C (Read across from structural homologue "[938-147-6] Fatty acid chlorides, C8-14 (even numbered), reaction products with glycine").
Key value for chemical safety assessment
Additional information
The autoflammability of the structural homologue "[938-147-6] Fatty acid chlorides, C8-14 (even numbered), reaction products with glycine" was determined. No self-ignition temperature was observed up to the maximum test temperature of 401 °C, according to the testing guideline for auto-flammability (solids - determination of relative self-ignition temperature) in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.16.
The composition of the source material [938-147-6] Fatty acid chlorides, C8-14 (even numbered), reaction products with glycine only slightly deviates from the target material with regard to the C-chain distribution:
C-chain distribution of N-Alkanoyl glycin sodium constituents of the UVCB substances (normalised to 100%), melting ranges, boiling and physical state:
| Source material (Glycine, N-coco acyl derivs., sodium salts) | Target Material | |
| C8 | 4 -12 % | 3 -14% |
| C10 | 5 -12 % | 4 -10% |
| C12 | 55 -68 % | 75 - 90% |
| C14 | 14 -24% | - |
| C16 | < 8% | - |
| melting range | 141 -190°C | 143 -174°C |
| boiling behaviour | decomposition before boiling at 260°C | decomposition before boiling at 290°C |
| phys. state | white crystalline solid | white crystalline solid |
Compared to the source material the content of the main C-homologue (C12) of the target material is increased, whereas longer C-chain lengths are not present in the target material. All other constituents are identical and are present at comparable concentrations. The melting ranges and boiling behaviour of both substances are comparable. Therefore, it is reasonable to conclude that the auto flammability of source and target materials are in the same order of magnitude.
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.
