Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The toxicology of sulphur trioxide has been adequately described. The hazards associated with its corrosive or irritant nature (depending on the dilution) are known, and appropriate risk and safety phrases are in place. The immediate reaction with water to form sulphuric acid and the subsequent dissociation to hydrogen and sulphate ions in water coupled with the ubiquitous nature of both of those ions in physiological processes render further testing unnecessary.

Justification for classification or non-classification
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.
