Dusting Analysis
As a colorant, Pigment Red 190's primary function is aesthetic, not active. The concept of 'dusting' typically applies to active ingredients where a minimum concentration is needed for a therapeutic effect, which is not relevant here.
The Formula
Formulation
Stability
Pigment Red 190 is a highly durable perylene pigment, exhibiting excellent resistance to solvents, migration, heat (up to 200°C), and light. It maintains stability across a broad pH range, resisting both acid and alkali conditions. As it is insoluble in water, it is typically dispersed rather than dissolved in formulations. Optimal storage involves a tightly closed container in a dry, cool, well-ventilated environment, avoiding wet conditions.
