Ultramarine pigments are generally recognised as being amongst the safest available : for example, they are included in the US FDA "GRAS" (Generally Recognised As Safe) list for use in food-contact applications in 21 CFR § 178.3297. They are also not classed as hazardous under any EU legislation.

Please also note that the data above refers to "normal" use of these products eg in plastics etc : specialised applications such as cosmetics may be covered by specific legal requirements. Please contact us for further information in such cases.
