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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Explosiveness
Administrative data
Link to relevant study record(s)
- Endpoint:
- explosive properties of explosives
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties
Reference
The oxygen balance of an organic molecule is defined as:
[-1600 * (2X + Y/2 - Z)]/M,
with
• X = the number of carbon atoms in a molecule
• Y = the number of hydrogen atoms in a molecule
• Z = the number of oxygen atoms in a molecule and
• M = its molecular weight
An oxygen balance of zero would then denote a compound with a high propensity for explosive decomposition. High positive or negative values denote a low explosivity.
Methyl lactate has an oxygen balance of -138.3, which denotes a low explosive risk.
Description of key information
In accordance with column 2 of REACH Regulation 1907/2006 Annex VII, the study does not need to be conducted because on the basis of its chemical structures, there are no chemical groups in the molecule associated with explosive properties. Methyl (S)-lactate does not contain any of the group recognized as associated with explosive risk (Brethrick, Handbook of Reactive Chemical Hazards, Butterworth, London, 1979).
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
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.
