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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The pH of hydrobromic acid (the strong mineral acid formed by hydrogen bromide [HBr] in water) is known to be acidic – the pH of a 62 % solution is 1. Toxicological studies have shown that HBr gas and hydrobromic acid are well known to cause burns to skin and eyes. This fact is reflected in the EU classification and labelling of HBr and hydrobromic acid as they are classified/labelled with the symbols "C" and "Xi" and the risk phrases "R35" and "R37".
SKIN
Quevauviller, A., et al. (1974) reported that upon application to rat skin HBr causes more severe burns than hydrogen chloride (HCl) or hydrogen iodide (HI).

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.
