Quinacridone

Quinacridone (CAS 1047-16-1), also marketed as C.I. Pigment Violet 19, PV19, and CINQUASIA RED, is a high-performance organic pigment valued across demanding colorant applications.

It delivers exceptional lightfastness, heat stability, and color strength that synthetic alternatives struggle to match, making it a benchmark pigment in premium color formulations.

In automotive OEM and refinish coatings, PV19 produces clean violet-to-red hues that retain color integrity under prolonged UV exposure and high-bake oven cycles.

Plastics compounders incorporate it into engineering polymers where processing temperatures would degrade conventional organic pigments. Printing ink manufacturers rely on it for high-end packaging.

These inks require consistent gamut and resistance to bleed or migration. Cosmetic formulators use C.I. Pigment Violet 19 in color cosmetics such as lipsticks and eyeshadows.

Regulatory compliance and batch-to-batch color consistency are critical sourcing criteria. Quinacridone is supplied as a dry powder in both crude and finished pigment forms.

Particle size and surface treatment vary by application target. Standard commercial grades include uncoated pigment grades for ink and coating systems, and resin-coated or flushed grades.

These are optimized for plastics and high-viscosity applications. Cosmetic-grade material is available with documentation supporting compliance with regional color additive regulations.
