Last year, the International Fragrance Association (IFRA) published a new method for the testing of 57 potentially allergenic fragrances in response to calls to do so by the European Scientific Committee on Consumer Safety, which also proposed a amendment to the EC regulation No. 1223/2009.

This new analytical method uses gas chromatography and mass spectrometry, to detect and to quantify the 57 fragrance substances and their relevant isomers at a concentration higher than 0.002% (20 mg/kg) in ready-to-inject fragrance materials and oils.

Merck developed two ready-to-use certified reference material mixtures suitable for use as calibrants for the new IFRA method.
