It appears as a fine blue powder and is classified under EINECS 223-333-5. This compound is specifically formulated for use in paper and textile dyeing applications where water solubility and batch consistency are critical. The dye is supplied in powder form, requiring dissolution in hot water prior to application.
As a direct dye, it bonds to cellulose fibers without the need for a mordant, making it suitable for cotton and paper substrates. The dye exhibits moderate lightfastness and washfastness typical of direct azo dyes in this class. Standard industrial grades contain less than 2% moisture content and less than 0.5% insoluble matter. The particle size distribution is typically under 100 microns to ensure uniform dispersion during dye bath preparation.
Buyers in the paper manufacturing and textile printing sectors use Direct Blue 1 for achieving consistent blue shades in bulk production. It is commonly applied in offset printing inks, tissue paper tinting, and low-cost cotton dyeing. Trade terms are typically FOB Ahmedabad, with packaging in 25kg polypropylene bags lined with polyethylene. Buyers should confirm compatibility with their specific substrate and dyeing process before bulk purchase.

Before ordering Direct Blue 1 from Sparrowings International, verify the batch-specific CAS and EINECS numbers match the supplier’s declaration. Request a Certificate of Analysis showing moisture content, insoluble matter, and heavy metal limits. Confirm the dye is intended for industrial use only and not for food, cosmetics, or pharmaceutical applications. Ensure the supplier provides SDS in English and local language if required for import clearance.
Logistics are typically handled via FOB Ahmedabad port, with lead times of 10 to 15 days after order confirmation. Payment terms are commonly T/T in advance or LC at sight. Packaging is in 25kg polypropylene bags with inner PE lining, stacked on wooden pallets. Buyers should specify Incoterms and request container loading photos to confirm handling integrity. No express shipping options are advertised.
Quality checks should include visual inspection for color uniformity, particle clumping, and foreign matter. Conduct a solubility test by dissolving 1g in 100ml hot water and filtering through 0.45μm membrane to check for insolubles. Request a UV-Vis absorption spectrum to confirm the dye’s peak absorbance aligns with the standard at approximately 600nm. Retain a sample from each batch for future shade matching and regulatory audits.
