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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
Additional information
The endpoints used to describe the intrinsic properties of the REACh substance are filled in with data obtained on the substance itself (i.e. without water): melting point; boiling point and density. The endpoints used to assess the classification and hazard properties of the REACh substance are filled in with data obtained on commercial products (i.e. aqueous solutions): surface tension, flash point, auto flammability, flammability, viscosity and metal corrosion.
For some endpoints, an analogy is made with the substance EC 939-455-3 (C8-18 AAPHS): substances EC 242-893-1 (target) and EC 939-455-3 (source) share indeed the same functional groups, the same general composition and the same main component (C12 alkylamidopropylhydroxysultaine).
In the following table are summarized the physico-chemical properties of the REACh substance:
Endpoint |
Experimentalresult |
Melting point |
55°C at 101 325 Pa |
Boiling point |
311.6°C at 101 325 Pa |
Relative density |
1,304 at 20°C |
Particle size distribution |
Waiving in accordance with column 2 of REACH Annex VII (a granulometry study does not need to be conducted as the test item is manufactured and used in a non-solid (liquid) form) |
Vapour pressure |
0.000000023 Pa at 20°C |
Partition coefficient |
2.1 at 25°C |
Water solubility |
556g/l at 20°C |
Surface tension |
38.5 mN/m at 20°C |
Flash point |
No flash point was observed up to 120.0 °C (aqueous solution) |
Auto Flammability |
396°C at 101 325 Pa |
Flammability |
Non flammable (aqueous solution) |
Explosiveness |
Non explosive |
Oxidising properties |
Non oxidising |
Stability in organic solvents |
Waiving according to column 2 of REACH annex IX column 1 of end point 7.15. The study is only required if stability of the substance is considered to be critical. Stability in solvents is not critical for this substance. |
Dissociation constant |
In accordance with column 2 of REACH Annex IX, dissociation constant (required in section 7.16) does not need to be conducted as it is scientifically not possible to perform the test (an amphoteric UVCB substance). The substance is always in an ionised form.. |
Viscosity |
28.65 mPa.s at 20°C (aqueous solution) |
Metal corrosivity |
Non corrosive on metal |
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).
