Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrogen peroxide (87%) does not fulfil the criteria for classification as an explosive, which was demonstrated in a guideline study following EU Method A.14 (Degussa 1977).
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
The following text is copied from the EU Risk Assessment Report (European Commission 2003):
"Hydrogen peroxide can decompose explosively. At atmospheric pressure vapours containing 26 mol % or more hydrogen peroxide can be exploded by a spark, by contact with catalytically active materials initially at room temperature, or by “non-catalytic” materials at elevated temperatures. Because of the high relative volatility of water to hydrogen peroxide, the danger of vapour phase explosion on storage of liquid hydrogen peroxide will be encountered only with concentrated solutions above 74% at elevated temperatures (Schumb et al., 1955). At concentrations above 86% wt. the liquid itself can be made to explode (CEFIC, 1998). Hydrogen peroxide (87%) does not however fulfil the criteria for classification as an explosive (Degussa AG, 1977a)."
Justification for classification or non-classification
An aqueous solution of hydrogen peroxide containing 87 % w/w was not classified as an explosive in the steel tube test according to the
guideline study applying EU Method E.14 (Degussa 1977).
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.
