Description of key information

- Thymol is not a flammable solid as tested according UN method N.1 (Currenta, 2010).
- No pyrophoric properties: Experience in production or handling shows that the substance does not ignite spontaneously on coming into contact with air at normal temperatures (i.e. the substance is known to be stable at room temperature for prolonged periods of time).
- Does not emit flammable gases in contact with water: The structural formula of the test item contains none of the functional groups quoted in Manual of Tests and Criteria, appendix 6, article 5.3).

Key value for chemical safety assessment

Additional information

Justification for classification or non-classification

According to the information summarized in this below, no classification on flammability is needed for Thymol:

- As solid, the flash point is 116°C at 1013 hPa (Currenta, 2008);

- Thymol is not a flammable solid (Currenta, 2010)

- No pyrophoric property, based on experience from production and handling (Currenta, 2010);

- Thymol does not emit flammable gases in contact with water (Currenta, 2010).

Meanwhile, thymol is also not flammable according to GHS (Regulation EC 1272/2008).
