CI 15850 (D&C Red No. 6 Or 7)
What is CI 15850 (D&C Red No. 6 Or 7)?
CI 15850, also called D&C Red No. 6 or D&C Red No. 7, is a synthetic monoazo pigment created via chemical coupling of diazotized toluidine with beta-naphthol. This oil-soluble dye delivers a brilliant red shade prized in cosmetics. Commonly found in lipsticks, rouges, eyeshadows, and nail enamels, it functions by selectively absorbing light wavelengths outside the red spectrum, reflecting intense color for visual enhancement. Approved by the FDA as a certified color additive for cosmetics and drugs when pure, it adheres to strict specifications limiting impurities like heavy metals and amines. In formulations, it disperses evenly to maintain shade uniformity across production batches and product shelf life, supporting aesthetic quality without altering texture.
