This strong violet pigment is a complex of manganese ammonium pyrophosphate. It is stronger violet than ultramarine and is primarily used in eye products. Manganese violet decomposes in water and cannot be used in hydrated emulsion systems. It is relatively stable in acid ph ranges. Along with the standard shade of manganese violet, we also offer material that is considerably redder in mass tone and tint. It is slightly weaker in strength, but more transparent. The red tone and transparency are benefits for customers using carmine in formulations. Addition of this grade will allow the formulator to reduce the amount of carmine required which will give excellent cost savings.
