D&C Red 7
Description
D&C Red 7 (CAS 5281-04-9 ), also known as Lithol Rubine BK, is a synthetic azo pigment approved for use in cosmetics and personal care products in the United States. It delivers a vivid, bluish-red hue with strong tinting strength. This pigment is a reliable colorant choice across regulated and industrial applications. In cosmetics, it is used to achieve deep red and pink shades in lipsticks, lip glosses, blushes, and nail lacquers. Color consistency and batch-to-batch stability are critical for formulators using this pigment. Printing ink manufacturers incorporate it into lithographic and flexographic inks for packaging applications requiring bright reds. In industrial coatings, it functions as a pigment in solvent-based and water-based systems where opacity and lightfastness are priorities. Adhesive and sealant producers also use it for color-coding products. D&C Red 7 is supplied as a fine powder or press cake, with particle size and dispersibility varying by grade. Cosmetic-grade material is available to meet FDA 21 CFR specifications for the US market. This regulatory benchmark ensures the material is suitable for sensitive applications. Technical grades are also available for industrial ink and coating applications where cosmetic compliance is not required. Contact us for supply of D&C Red 7 Request Quote
