Direct Yellow 8 is a sodium salt azo dye with the CAS number 10130-29-7 and EINECS number 233-365-1, appearing as a fine yellow powder. Its molecular formula is C24H19N4NaO5S2, indicating a disulfonated structure that enhances water solubility. It produces a bright yellow shade in aqueous solutions and is used primarily in paper and textile dyeing applications.
This dye is classified as a direct dye, meaning it bonds directly to cellulose fibers without mordants. It is suitable for dyeing cotton, viscose, and paper substrates. The dye has limited solubility in organic solvents and shows good affinity for paper pulp. Typical applications include low-cost printing inks, decorative paper, and disposable textiles where high lightfastness is not required.
Buyers commonly source Direct Yellow 8 for paper mills producing colored stationery, textile printers producing low-end garments, and manufacturers of packaging materials. The product is supplied in 25kg kraft paper bags with polyethylene lining. Buyers should confirm batch consistency through absorbance measurements and request a test report for sulfonate content to ensure dyeing uniformity.
