New Reference Materials for Quality Control of Fragrances and Cosmetics: Neat Reference Materials for Allergenic Fragrances Listed in the New IFRA Method

Quality Control of Fragrances

In Analytix Reporter, Issue 3, we presented two certified reference material mixes and a chromatographic application for use with the new IFRA method for the testing of 57 potentially allergenic fragrances. This new method allows the screening of complex fragrance mixtures for the presence of these chemically defined allergens by GC-MS.

We now introduce a number of new individual reference materials as neat compounds for some of the allergenic fragrances contained in the mixes. These reference materials have been certified by quantitative NMR (qNMR) and are traceable to NIST SRMs. The certificate contains information about traceability, homogeneity and stability and the values are given with calculated uncertainties.
