Acid Blue 40 is a synthetic organic dye with CAS number 6424-85-7, also known in industry as Weak Acid Blue 2G. The chemical formula C22H16N3NaO6S confirms its sodium salt structure, and its EINECS registration 229-190-5 aligns with EU compliance for textile and leather applications. Produced as a fine powder in Gujarat, India, this acid dye is designed for bonding with protein and polyamide fibres under acidic conditions.
The dye delivers vibrant blue shades with strong colour fastness to light and washing, typical for acid dyes used in wool, silk, and nylon substrates. Its molecular structure ensures high solubility in water, enabling uniform penetration in dyeing processes. Standard for this class, it exhibits good levelling properties, reducing streaks or uneven colouration in batch production.
Textile manufacturers and leather finishers use Acid Blue 40 for its consistency in industrial dyeing, particularly in polyamide fibres and leather goods. Buyers typically source it in bulk powder form for large-scale operations, with applications ranging from apparel to automotive interiors. Trade terms and packaging specifications should be confirmed directly with Sparrowings International, as these are not stated in the listing.
