Formulation
Stability
CI 77007 exhibits significant incompatibility with acidic conditions, particularly at pH levels below 6. Contact with acids can lead to the release of hydrogen sulphide, a highly toxic and flammable gas with a characteristic rotten egg odor, and may cause color fading. Formulators can mitigate this risk by opting for acid-resistant grades of Ultramarines. While insoluble, it can be effectively dispersed in both water-based and oil-based formulations.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a direct assessment of CI 77007. In the European Union, it is an approved colorant under the EC Cosmetics Regulation (Regulation (EC) No. 1223/2009) Annex IV, where specific maximum concentrations and permitted applications are defined. In the United States, the FDA approves CI 77007 (Ultramarine Blue) for all cosmetic uses, with the sole exception of lip products. It is deemed safe for externally applied cosmetics, including those around the eye area, when used in accordance with good manufacturing practices.
