Description

DC Red No 30 (CAS 2379-74-0), also known as D&C Red #30 and Japan Red 226, is a synthetic organic pigment used to impart vivid red-to-pink coloration across cosmetic, industrial, and printing applications. Regulatory acceptance under D&C and Japan Red designations makes it a recognized option for formulators working within defined colorant approvals. In personal care, it is used to color lipsticks and blushes.

It is also utilized in pressed powders where strong tint strength and skin-contact compliance are required. Printing ink manufacturers incorporate it into packaging inks where consistent hue and substrate adhesion are priorities. Coatings and industrial paint formulators use it to achieve saturated red shades in solvent-based and specialty systems. Textile and paper dyeing operations also draw on this pigment for surface coloration.

This pigment is ideal where surface coloration rather than fiber penetration is the target outcome. It is supplied as a fine dry powder to ensure easy dispersion within various manufacturing processes. Cosmetic-grade material is available meeting D&C specifications applicable to externally applied products. Technical-grade material serves industrial coatings and printing ink applications for diverse sectors.

Buyers should confirm grade and regulatory status against their target market colorant approval framework before sourcing. This ensures compliance with local safety standards and application requirements.
