Lithol Rubine B

Lithol Rubine B (CAS 5858-81-1), also known as D&C Red No. 6 and Pigment Red 57, is an azo-based organic pigment delivering a strong, bluish-red hue across a broad range of industrial and consumer applications.

Its combination of color strength and regulatory acceptance in cosmetic markets makes it a practical choice for formulators and procurement teams sourcing red colorants for diverse manufacturing needs.

In personal care and cosmetics, it is approved as D&C Red No. 6 for use in lipsticks, blushes, and other leave-on products where a vivid red tone is required for high-end aesthetic results.

Printing ink manufacturers rely on Pigment Red 57 for offset and gravure inks, particularly in packaging applications demanding consistent, high-density color reproduction and reliable performance on various substrates.

Plastics and polymer processors incorporate it to achieve uniform red coloration in films, molded parts, and masterbatches. Textile and paper producers also use it as a surface colorant for bright red shading.

Lithol Rubine B is supplied as a fine powder or press cake, with particle size and dispersion characteristics varying by grade. Standard commercial grades include cosmetic-grade material meeting specific purity requirements.

Technical-grade pigment is available for industrial ink and plastics applications. Barium and calcium salt variants are available, and buyers should confirm the specific salt form when sourcing for their formulations.
