从India供应商批发进口Acid Yellow 23 — FOB条款

Acid Yellow 23 is a synthetic organic dye used for direct dyeing and printing of wool, silk, vinegar-treated fabrics and polyamide fibres. It is also supplied as a barium salt for applications in paper, leather, soap, pharmaceuticals, plastics and aluminium surface shading. The dye is water-soluble and delivers a bright yellow hue with good lightfastness in textile applications, making it a standard choice for vibrant colouration in natural and synthetic fibres.

The product is available in powder form and is classified under the synonyms Acid Yellow N and Acid Tartrazine in industrial catalogues. It is typically used in concentrations of 0.5 to 3% by weight of the substrate, depending on the desired shade intensity. For leather and paper, the barium salt variant is preferred due to its stability in alkaline conditions, a standard requirement for these industries. The dye exhibits good compatibility with other acid dyes and is often combined to achieve specific colour profiles.

Primary buyers include textile mills, leather processors and manufacturers of inks, cosmetics and food colourants. In textile applications, it is valued for its uniformity and resistance to bleeding during washing. For bulk orders, the dye is typically packed in 25 kg or 50 kg multi-layer paper bags with a polyethylene inner liner to prevent moisture absorption. Importers should confirm packaging specifications and stability under local storage conditions before placement of orders.
