Acid Yellow 3

Acid Yellow 3 (CAS 8004-92-0 ), commercially recognized as Quinoline Yellow and approved as E104 , is a synthetic quinoline-based dye used to impart bright greenish-yellow coloration across industrial and regulated applications. It is available as both a water-soluble acid dye form and an oil-soluble variant, covering a broad range of substrate and formulation requirements. In textile and leather processing, it is applied to protein and polyamide fibers. This includes wool, silk, and nylon, delivering strong color fastness under acidic dyebath conditions. Ink and printing formulators use it to achieve vivid yellow tones in water-based inks for packaging and commercial print runs. In plastics, the dye is incorporated into polymer matrices where surface coloration or mass pigmentation of films and molded parts is required. As E104, it is also permitted in certain food, beverage, and cosmetic applications. These applications are common in jurisdictions where regulatory approval is in force. Acid Yellow 3 is supplied as a fine powder or granulate, with water-soluble grades standard for textile and food-contact applications. Food-grade material conforming to E104 specifications is available for regulated end uses, while technical-grade product serves industrial dyeing and ink formulation. Purity levels and solubility profiles vary by grade. Buyers should confirm specification alignment with their application requirements. This ensures the product meets the necessary performance standards for specific industrial, food, or cosmetic manufacturing processes. Contact us for supply of Acid Yellow 3 Request Quote
