Acid Red 14 - Carmosine Ws is a synthetic acid dye used for colouring natural and synthetic fibres, notably wool, nylon, silk, paper and leather. The product is supplied as a water-soluble powder, formulated from premium acids and compounds, and is designed for industrial applications where vibrant red shades are required. Karsandas Mavji, based in Mumbai, Maharashtra, packages the dye in multiple options to suit bulk and small-scale buyers.
This dye variant typically exhibits strong lightfastness and resistance to washing, making it suitable for textiles exposed to frequent laundering. In the dyeing industry, Carmosine Ws is often selected for its ability to produce consistent colour yields across different substrates, with a standard molecular formula of C20H12N2Na2O7S2. The powder form ensures easy dissolution in water, a key factor for uniform dyeing in industrial processes.
Manufacturers of wool, silk and leather goods are common buyers, along with producers of inks and coated papers. The dye is also used in the food industry under regulated conditions, though buyers should confirm compliance with local food-grade standards. For bulk imports, buyers should verify packaging integrity and storage conditions, as the dye is sensitive to moisture and direct sunlight.

Before ordering Acid Red 14 - Carmosine Ws from Karsandas Mavji, verify the dye’s purity and compliance with your industry’s standards. Request a certificate of analysis to confirm the molecular structure and absence of impurities, as these directly impact colour consistency and substrate bonding.
Confirm logistics details such as lead time, Incoterms (e.g., FOB or CIF), and payment terms. Since the supplier is based in Mumbai, discuss port of shipment (likely Nhava Sheva) and whether the dye is packed in moisture-resistant containers to prevent degradation during transit.
Conduct quality checks upon receipt, including solubility tests and colour matching against samples. For textiles, perform wash and lightfastness tests using ISO 105 standards to ensure the dye meets performance expectations. Always retain documentation for traceability and compliance purposes.
