Import Acid Yellow 186 — Buy in wholesale FOB from Supplier in India

Acid Yellow 186 is an acid dye with CAS number 10103-29-7, also known by the alternative name Coomassie Yellow 6G, supplied by Sparrowings International from Gujarat, India. Its molecular formula is C24H19N4NaO5S2, placing it in the monoazo or related azo dye chemical class typical for acid dye applications. The product is offered in powder form, which is standard for industrial dye handling and metering. Sparrowings International lists this dye for use on leather, textile, and polyamide substrates, reflecting its sulfonated structure that enables water solubility and fibre affinity.

The dye's sodium salt formulation (indicated by Na in the molecular formula) provides solubility in aqueous dyebaths, a typical typical characteristic of acid dyes designed for protein and polyamide fibres. Acid Yellow 186 typically exhibits moderate to good lightfastness and wet-fastness properties on nylon 6 and nylon 6,6, though exact ratings depend on application concentration and after-treatment. The powder form suggests a standardised strength, often quoted at a specific concentration (for example, 200% or similar) against which colour matching is performed. Typical moisture content for such dye powders ranges from 3% to 5% by weight at time of packing, though buyers should request a batch certificate for precise values.

This dye finds primary application in automotive textiles, sportswear, and fashion hosiery where polyamide colouration is required, as well as in leather finishing for footwear and accessories. Textile dyers and leather processors form the core buyer segment, often working to tight colour-matching tolerances (Delta E <1.0 against standard). Trade terms, MOQ, and lead time are not stated in the listing, so importers should confirm these directly with Sparrowings International along with any required certifications for their destination market.
