Science
Mechanism of Action
This ingredient operates as a cosmetic colorant by physically reflecting light in the violet spectrum, providing aesthetic appeal to formulations. Its particulate nature allows it to also act as a filler, adding bulk and improving application consistency, and as a binder, helping to hold other ingredients together for a smooth and even texture.

The Formula
Formulation
Stability
CI 77742 is insoluble in water but exhibits excellent dispersibility in various solvents, including oil, glycerin, and propylene glycol, facilitating its integration into both oil-based and water-based formulations. It maintains stability within a pH range of 6.0 to 9.0 and shows moderate heat stability up to 250°C. However, its stability is compromised by strong acids, strong alkalis, and exposure to high relative humidity combined with sulfur dioxide (SO2), which can induce a colorimetric shift from violet to grey.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has deferred evaluation as its safety has been assessed by the FDA. The FDA approves Manganese Violet as a color additive exempt from certification for use in cosmetics, including lip and eye areas, provided it conforms to FDA specifications. It is also approved for unrestricted use in all cosmetics within the European Union. While generally considered safe and non-toxic, a patch test is recommended for individuals due to a low potential for skin irritation or allergic reactions.
