This chapter aims at providing an overview of the main contaminants that can be present in cosmetic products at trace levels. These may come from a large variety of sources that are considered in this work (e.g., impurities of raw materials, the manufacturing process, storage conditions, potential migration from the final packaging to the product or chemical changes caused by instability of the cosmetic). An overview of the regulations of various countries is included. The literature concerning analytical methods for determining contaminants such as some metals and metalloids, nitrosamines, 1,4-dioxane, hydroquinone, formaldehyde and acrylamide is reviewed. Future perspectives on the need for a strict analytical control of these substances to reduce risks to health and updated methods of analysis are also highlighted.
