The IFRA analytical methods represent the recommendations of the IFRA Analytical Working Group. They are intended to be used as a common tool for the dialogue between the different partners of the fragrance industry. Possible modifications for the internal use by a company is their sole responsibility and should be validated against the original IFRA procedure.
Quantifation of Potential Fragrance Allergens in Fragrance Compounds
The IFRA Analytical Working Group has developed an analytical method that allows the determination of the presence of potential allergens in fragrance compounds. This makes reference to the fragrance ingredients defined by the European Commission's Scientific Committee for Non-Food Products (SCCNFP now called the SCCS, Scientific Committee for Consumer Safety) as potential allergens and which are included in the seventh amendment to the European Cosmetics Directive for the purpose of labelling in finished cosmetic products.
An article extensively describing this method as well as results of testing was published in J.Agric.Food Chem. 2003, 51, 6398-6403.
