there is no so much published about SPE of oxidation dyes. 
 The more related document is an extraction with ChemElut S: Determination of Aromatic Amines Derived from Azo Colorants by GC/MS using Supported Liquid Extraction Chem Elut S Cartridges (agilent.com) 
 And for the preservatives from finished cosmetic products have a look to
