Import Direct Yellow 12 — Buy in Bulk from Supplier in India

Direct Yellow 12, also known as Direct Chrysophenine G, is a water-soluble azo dye with C.I. 24895 and CAS number 2870-32-8. It is designed for dyeing cellulosic fibers including cotton, flax, viscose rayon, acetate, and jute, and is also used in leather and paper coloring applications. The dye exhibits good solubility in hot water and moderate affinity for cellulose substrates under alkaline dyeing conditions.

This compound belongs to the direct dye class, meaning it applies without mordants and relies on molecular structure for fiber adhesion. Its chemical structure includes a diazo group and sulfonic acid groups that enhance water solubility and substantivity. Typical industry standards for this dye include a purity level above 85% and moisture content below 5%, though these are not guaranteed by the supplier. It is commonly supplied as a fine powder with a bright yellow hue and low levels of insoluble matter.

Buyers in the textile, leather finishing, and paper industries use Direct Yellow 12 for cost-effective, non-ionic dyeing processes. It is often selected for applications requiring moderate lightfastness and washfastness, particularly where bright yellow tones are needed without the cost of reactive or vat dyes. Trade terms are typically FOB Surat, with bulk packaging in 25kg polyethylene-lined bags. Buyers should confirm dyeing temperature profiles and pH requirements before use.
