scope:

NEN-EN 16521 describes a GC/MS method for the assay of 12 phthalates, amongst which the 8 phthalates regulated by the European cosmetic regulation 1223/2009 [16]. This method is given for the analysis of samples ready for analytical injection from cosmetic products or raw materials used in cosmetic products. Samples should be compatible with GC analysis possibly after dilution. This method does not include requirements for the preparation of samples in cosmetic matrices for which direct injection in GC is not feasible.
