EC number: 290-335-0 | CAS number: 90131-24-1 Extractives and their physically modified derivatives such as tinctures, concretes, absolutes, essential oils, oleoresins, terpenes, terpene-free fractions, distillates, residues, etc., obtained from Spilanthes acmella, Compositae.
The lowest auto-ignition temperature of the test item was determined to be 277 °C in the preliminary test.
The following table show the results of the main tests.

3rdmain test (2 K)
The lowest auto-ignition temperature of the test item was determined to be 266 °Cin the main test. Due to safety reasons and according to the guidelines the lowest measured temperature at which an ignition was observed was rounded to the next lower number divisible by 5, giving a value of 265 °C.
The study was performed in order to determine the auto-ignition temperature of test item according to EU A.15 guideline.The lowest auto-ignition temperature of the test item was determined to be 266°C in the main test.
The three lowest results of the tests with 2 K steps were within a range of less than 10K. Therefore, the results were considered as valid.
Due to safety reasons and according to the guidelines the lowest measured temperature at which an ignition was observed was rounded to the next lower number divisible by 5, giving a value of 265 °C.
The auto-ignition temperature of the test item according to the auto-ignition test conditions in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.15. was 265 °C.
A fully reliable experimental study, conducted according to EU A.15 guideline is available.
It is considered as a key study, and the result is retained as key data.
This parameter is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
