Description of key information

In order to assess the auto-flammability of Ginger selective extract (UVCB), a screening test was performed according to the EU A.15 and DIN51794, under GLP conditions. In this study, The auto-flammability of Ginger selective extract was found to be 235 ºC at 999-1028 hPa. Ginger CO2-to extract has an auto-flammability of 235ºC at standard pressure (WOE approach from Ginger CO2-Se extract). See additional information for background information about the WOE approach.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

235 °C

Additional information

No study information is available regarding the auto-flammability of the substance Ginger oil CO2-Total Extract. However, there is sufficient weight of evidence information available from two independent sources to provide appropriate evidence to fulfil the information requirement. Therefore, in line with section 1.2 of Annex XI in regulation (EC) No 1907/2006, a weight of evidence (WoE) approach was used. In this WoE approach the results from EC A.15 and DIN 51794, GLP studies, performed on two qualities of ginger oil extracts (Ginger CO2-SE extract and Ginger oil Hot Flavor CO2-TO extract) were used in order to fulfil the auto-flammability endpoint for Ginger oil CO2-Total Extract. These two qualities of ginger oil constitute to the volatile and the non-volatile fraction of the target UVCB (Ginger oil CO2-Total Extract). The two fractions combined cover the constituents present in Ginger oil CO2-Total Extract, albeit in higher concentration ranges in both fractions. By assessing the study results of both fractions in a WoE approach, there is adequate and reliable information available to assess if Ginger oil CO2-Total Extract has or has not a particular dangerous property. For this end-point, the selective extract value was selected as worst-case, 235 °C.
