direct Blue 8 is a direct dye with the CAS number 2429-71-2 and molecular formula C34H24N4Na2O10S2, supplied as a fine powder. It is classified under EINECS 219-382-7 and originates from Gujarat, India. This dye is specifically formulated for textile applications where consistent colouration and good wet fastness are required. The product is delivered in dry, free-flowing form with no visible clumping or moisture retention.
As a direct dye, it bonds directly to cellulose fibres without requiring a mordant, making it suitable for cotton, viscose, and rayon. Typical industry standards for this dye class include a pH stability range of 5 to 9 and a maximum moisture content of 5%. The powder form ensures uniform dispersion in dye baths, reducing the risk of uneven dyeing. It is not recommended for protein fibres such as wool or silk due to low affinity.
Buyers in the textile manufacturing sector, particularly in South Asia and Southeast Asia, source this dye for low-cost, high-volume dyeing operations. Typical packaging is 25 kg polypropylene bags with inner polyethylene lining. Trade terms are typically FOB Mumbai or EXW Ahmedabad. Buyers should confirm batch-to-batch consistency through UV-Vis spectrophotometry and request a Certificate of Analysis for purity and insoluble matter.

Before placing an order, verify the batch-specific Certificate of Analysis for active dye content, insoluble matter, and heavy metal limits. Request test results for lead, cadmium, and chromium according to REACH and ZDHC thresholds. Confirm that the dye is free from banned amines by asking for a third-party lab report. Do not rely on supplier claims without documentation.
Logistics are typically handled via FOB Mumbai or EXW Ahmedabad. Lead times vary from 10 to 20 days depending on stock availability. Buyers should confirm Incoterms, container size (20 ft or 40 ft), and whether palletisation is included. Payment is commonly by TT in advance or LC at sight. Request a packing list with batch numbers and expiry dates.
Perform incoming quality checks using a spectrophotometer to compare shade against the approved standard. Test solubility by dissolving 1 g in 100 mL water at 85°C and filtering through a 0.45 µm membrane. Measure residue weight to confirm insoluble matter is under 0.5%. Retain a sample from each batch for future shade matching and dispute resolution.
