Description of key information
Isobutyl-R-lactate is considered to be non-explosive, based on screening-level assessment.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
- 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).
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:
Isobutyl-R-lactate does not contain any of these chemical groups. Although it is acknowledged that the above list is not exhaustive the molecular structure of the substance nevertheless clearly suggests that explosive hazards are absent. Furthermore, the oxygen balance of the molecule is –197, which is only marginally higher than the trigger value of –200, which allows classification of a substance as non-explosive even if chemical groups associated with explosive hazards are present. Based on this screening level assessment, testing of explosive properties of isobutyl-R-lactate is considered to be scientifically unjustified. Isobutyl-R-lactate is therefore not classified as an explosive substance.
Justification for classification or non-classification
Isobutyl-R-lactate does not contain any chemical groups that are associated with an explosive hazard. Furthermore, the oxygen balance of the molecule is clearly negative, with a value of –197. Isobutyl-R-lactate is therefore not classified as an explosive substance.
