Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 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
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
According to Regulation (EC) No 1272/2008 (CLP Regulation) and ECHA's CLP guidance, explosive properties are associated with the presence of certain chemical groups in a molecule which can react to produce very rapid increases in temperature and/or pressure.
Examples of such chemical groups are:
- C-C unsaturation (e.g. acetylenes, acetylides, 1, 2-dienes);
- C-Metal, N-Metal (e.g. Grignard reagents, organo-lithium compounds);
- Contiguous nitrogen atoms (e.g. azides, aliphatic azo compounds, diazonium salts, hydrazines, sulphonylhydrazides);
- Contiguous oxygen atoms (e.g. peroxides, ozonides);
- N-O (e.g. hydroxyl amines, nitrates, nitro compounds, nitroso compounds, N-oxides, 1,2-oxazoles);
- N-halogen (e.g. chloramines, fluoroamines);
- O-halogen (e.g. chlorates, perchlorates, iodosyl compounds).
Butyl-(S)-lactate does not contain any of these chemical groups. Although it is acknowledged that the list mentioned above is not exhaustive, the molecular structure of the substance nevertheless clearly suggests that explosive hazards are absent. - Conclusions:
- In accordance with a Column 2 adaption of REACH Annex VII, section 7.11., this study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.
- Executive summary:
In accordance with a Column 2 adaption of REACH Annex VII, section 7.11., this study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.
