Acid Black 172 from Sparrowings International is an acid dye with CAS number 61847-77-6, also known as Acid Black S-RL. It has the molecular formula C20H12N3NaO7S and is supplied in powder form, originating from Gujarat, India. The dye is specifically formulated for leather, textile, and polyamide applications, where it provides a consistent black color with reliable performance.
The dye’s chemical structure, featuring a sodium sulfonate group, enhances its water solubility, which is essential for even distribution in dye baths. In the textile industry, acid dyes like this are valued for their ability to produce vibrant shades on protein-based fibres, with typical light fastness ratings of 4-5 on the ISO 105 scale. For leather dyeing, the dye’s compatibility with tanning processes is a key advantage, as it can be applied at various stages without compromising the material’s integrity.
Sparrowings International markets this dye under its own brand name, targeting manufacturers in the leather and textile sectors. The powder form allows for flexible dosing, and the product is suitable for both small-scale testing and large-scale production. Buyers should confirm the dye’s performance under their specific processing conditions, including temperature and pH, to achieve the desired color depth and fastness.

Request technical data sheets that outline the dye’s performance under various pH and temperature conditions, as these factors are critical for achieving consistent results. Verify whether the supplier can provide samples for small-scale testing before committing to a bulk order.
Logistics discussions should cover packaging specifications, such as 20 kg or 25 kg bags, and the lead time for delivery from Gujarat.
