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:
- JUSTIFICATION FOR DATA WAIVING
In accordance with Annex VIII of REACH, Column 2, testing via inhalation is only appropriate if exposure of humans is likely. Vapour pressure of 2-Propenoic acid, 2-methyl-, tetracosyl ester(branched) was investigated during a study performed in accordance with ASTM D2879 - 97 Standard Test Method for Vapour Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope, which concluded that the substance has a vapour pressure below 100 Pa. In addition formation of aerosols during the use of the substance is unlikely. It is therefore concluded that exposure to 2-Propenoic acid, 2-methyl-, tetracosyl ester(branched) is unlikely and that it is not appropriate to investigate this route exposure.

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.
