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 triamine based amphoteric, glycinate with the shortest alkyl chain (Amines, N-(3-aminopropyl)-Nā€™-C12-18-alkyltrimethylenedi-, N-(carboxymethyl)derivs., sodium salts with CAS number 2060541-51-5) is available and used for the entire group. This value is low and also considered to be a worst case compared to the vapour pressure for the aqueous solutions of the substances which are used and put on the marked. Taking together the low acute oral toxicity profile within this group of substances 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.
