Elaboration procedures have been long, but finally the European Union has detailed and specific laws concerning cosmetics. They define a series of rules under banner of three main targets: product safety, proved efficacy, customer information. Are they clear, detailed and univocal for all Member States? Not exactly, but they have the good merit to settle the co-operation needed among the different professional characters: in first place, the formulator, who must be aware about forbidden and allowed ingredients and their limits of use. Then, the technical manager, who is responsible for the GMP observation and quality checks. Additionally, the safety assessor, who becomes the supervisor for the immediate and long-term toxicological impact of the cosmetic product. Finally, the responsible for launching the products on the market. He must particularly take care of the label norms, in addition to the above mentioned responsibilities, that he shares with the listed professionals. The result of such co-operation is the Cosmetic Dossier, as is requested by the law: a rational and detailed collection of all the relevant product informationís.
