- Executive summary:
In a GLP study (Défitraces, 2011), Ethylvanillin was tested for its explosive properties, when subjected to heat (heat sensitivity), shock or friction (mechanical sensitivity), according to the EC A14 method.
The results were the following:
Mechanical sensitivity (friction)
Six negative assays were recorded: No friction sensitivity was noted with the test item with a loading of 360 Newtons.
Mechanical sensitivity (shock)
Six negative assays were recorded: No shock sensitivity was noted with the test item.
Heat sensitivity (flame test)
Six negative assays were recorded: No heat sensitivity was noted with the test item.
Ethylvanillin was not considered to have explosive properties under our experimental conditions.
Reference
1. Mechanical sensitivity (friction)
1.1.Preparation of the test item
The melting point of the test item was situated between 76 and 78°C according to the MSDS. So it was not dried. The test item was sieved at 500 µm. The fraction passing through the sieve was used.
1.2.Safety-in-handling test
A small quantity of the test item was submitted to a friction by means of a metallic device. No sign of explosion was recorded.
1.3.Main test

3.3.Observed reactions
Assays using a tube with a hole of 6 mm diameter
Assay
No. 1: From 2 minutes 17
seconds to 2 minutes 42 seconds, intermittent yellow flame and white
smokes were observed. At 2 minutes 42 seconds, the test item overflowed
on the nut and around the tube. From 2 minutes 42 seconds to 3 minutes
52 seconds, a 0.5-m flame was observed all over the nut. From 3 minutes
52 seconds to 4 minutes 19 seconds, a 0.25-m yellow flame was observed
on the hole. From 4 minutes
19 seconds to 4 minutes 49 seconds, a little yellow flame was observed.
Assay No. 2: From 3 minutes 07 seconds to 3 minutes 35 seconds, intermittent yellow flame and white smokes were observed. At 3 minutes 35 seconds, the test item overflowed on the nut. From 3 minutes 35 seconds to 4 minutes 42 seconds, a flame was observed all over the nut. From 4 minutes 02 seconds to 5 minutes, a 0.5-m yellow flame was observed all over the nut and around the tube with intermittent projections.
Assay No. 3: From 3 minutes 25 seconds to 3 minutes 55 seconds, intermittent yellow flame and smokes were observed. From 4 minutes 05 seconds to 4 minutes 22 seconds, a yellow flame was observed all over the nut. From 4 minutes 22 seconds to 5 minutes, a 0.5-m yellow flame was observed all over the nut and around the tube. At 4 minutes 45 seconds, projections were observed.
Assays using a tube with a hole of 2 mm diameter
Assay No. 1: From 3 minutes 48 seconds to 4 minutes 48 seconds, intermittent yellow flame and white smokes were observed. At 4 minutes 48 seconds, the test item overflowed on the nut. From 4 minutes 48 seconds to 5 minutes, a 0.25-m flame was observed all over the nut and around the tube.

Description of key information
Ethylvanillin was not explosive in contact in with a flame, nor shock and nor friction.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
Only one study (Défitraces, 2011) dealing with the explosive properties was available and was selected as key study (quoted reliability 1 according to Klimisch scale). In this study, Ethylvanillin was tested for its explosive properties, when subjected to heat (heat sensitivity), shock or friction (mechanical sensitivity), according to the EC A14 method.
The results were the following:
Mechanical sensitivity (friction)
Six negative assays were recorded: No friction sensitivity was noted with the test item with a loading of 360 Newtons.
Mechanical sensitivity (shock)
Six negative assays were recorded: No shock sensitivity was noted with the test item.
Heat sensitivity (flame test)
Six negative assays were recorded: No heat sensitivity was noted with the test item.
Ethylvanillin was not considered to have explosive properties under our experimental conditions.
Justification for classification or non-classification
Ethylvanillin was tested for its explosive properties, when subjected to heat (heat sensitivity), shock or friction (mechanical sensitivity), according to the EC A14 method. All the experiments gave negative results.
In these conditions, Ethylvanillin is not classified for its explosive properties, according to CLP 1272/2008.
