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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 701-354-5 | CAS number: -
Acute Toxicity: inhalation
Administrative data
- Endpoint:
- acute toxicity: inhalation
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size
- Justification for type of information:
- The measured vapour pressure data on the freeze-dried β-Alanine, N-(2-carboxyethyl)-N-[3-[(2-carboxyethyl)amino]propyl]-, N-C12-18-alkyl derivs., trisodium salt CAS No 2136366-30-2 was very low at 2.6 Pa at 20°C. This value is low and also considered to be a worst case compared to the vapour pressure for the aqueous solutions of the substance which are used and put on the market. Taking together the low acute oral toxicity of this substance and the low vapour pressure of the aqueous technical product in combination with the low potential for aerosol formation, it is not considered justified from an animal well-fare perspective to perform any additional acute dose toxicity studies.

Applicant's summary and conclusion
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.
