Acid Blue 25 from Sparrowings International is a powder-form acid dye with the CAS number 6408-78-2 and the molecular formula C20H13N2NaO5S. It is also known as Weak Acid Blue AS and is identified by the EINECS number 229-068-1. This dye is primarily used for colouring leather, textiles, and polyamide materials, offering consistent performance in industrial dyeing processes.
The dye’s chemical structure ensures strong affinity for protein and polyamide fibres, providing vibrant blue shades with good light and wash fastness. Typical for acid dyes of this class, it exhibits solubility in water and is applied under mildly acidic conditions. The standard appearance is a fine powder, which dissolves uniformly in dye baths to ensure even colour distribution.
Leather tanneries and textile mills source Acid Blue 25 for its reliability in producing deep, uniform blue hues. The dye is particularly suited for applications requiring colour consistency across large batches. Buyers should confirm compatibility with their specific materials and processes, as well as the supplier’s ability to meet bulk order requirements. Originating from Gujarat, India, the product is positioned for both domestic and export markets.

Prior to ordering Acid Blue 25 from Sparrowings International, verify the dye’s CAS and EINECS numbers to ensure it matches your regulatory and application requirements. Confirm the supplier’s ability to provide batch-specific test results for light and wash fastness, as these properties are critical for leather and textile applications. Request a sample for laboratory testing to validate performance in your production process.
Clarify the Incoterms offered by Sparrowings International, as these will determine the point at which responsibility for the shipment transfers to you. Typical options for dye exports from Gujarat include FOB Nhava Sheva or CIF to your destination port. Discuss payment terms, as bulk dye orders often require advance payment or a letter of credit. Ensure the packaging is suitable for international shipping, with moisture barriers to prevent clumping.
Upon receipt, conduct quality checks to confirm the dye’s solubility, colour consistency, and absence of impurities. Perform a dye trial on a small batch of your material to assess compatibility and colour development. Request documentation such as the COA, MSDS, and any relevant certifications to ensure the product meets your quality and regulatory standards. Store the dye in a cool, dry place to maintain its stability until use.
