General Description
D&C Red 33 is a synthetic, water-soluble azo dye approved for use in cosmetics and personal care products. It is widely used to impart bright red to pink shades in formulations, offering excellent color consistency, stability, and vibrancy. D&C Red 33 is commonly supplied as a fine powder or granules and dissolves easily in water-based systems, making it suitable for a broad range of cosmetic applications.

It is commonly found in lipsticks, lip glosses, blushes, liquid soaps, shampoos, bath products, and mouthwashes. In skincare and hygiene products, it enhances visual appeal and product differentiation. Cosmetic manufacturers prefer D&C Red 33 for its good stability across a wide pH range and its compatibility with other cosmetic ingredients. It is widely used in rinse-off and leave-on formulations that require reliable and repeatable color performance.
