Manganese Violet is a violet pigment used the formulation of makeup, hair coloring products, bath products, nail polish and skin care products.
The most stable oxidation state for manganese is +2, which has a pale pink color, and many manganese(II) compounds are known, such as manganese(II) sulfate (MnSO 4) and manganese(II) chloride (MnCl 2). This oxidation state is also seen in the mineral rhodochrosite (manganese(II) carbonate).n 2+ often competes with Mg 2+ in biological systems. Manganese compounds where manganese is in oxidation state +7, which are restricted to the unstable oxide Mn 2 O 7 and compounds of the intensely purple permanganate anion MnO 4 â , are powerful oxidizing agents.
