Chemical Properties and Composition

Indigo Blue is a dark blue crystalline powder with a sublimation point of 390–392°C (734–738°F). Its chemical formula, C₁₆H₁₀N₂O₂, underscores its complex molecular structure, which contributes to its stability and dyeing efficiency. Notably, it is insoluble in water, alcohol, and ether but highly soluble in solvents like DMSO, chloroform, and concentrated sulfuric acid. This solubility profile makes it ideal for industrial dyeing processes.

Key Applications in Textile Industry

The primary application of Indigo Blue lies in the dyeing of cotton yarn, particularly for denim production. A single pair of blue jeans typically requires 3–12 grams of dye, making it a cost-effective solution for mass manufacturing. Beyond denim, it is also used for wool and silk, offering vibrant, long-lasting coloration. Its compatibility with stone washing and acid washing processes further enhances its appeal in the fashion industry.

Packaging and Transportation

Indigo Blue is available in multiple packaging options to suit diverse logistical needs:

• 20kg cartons: 9mt (no pallet) in 20’GP container111; 18tons (with pallet) in 40’HQ container111
• 25kg bags: 12mt in 20’GP container111; 25mt in 40’HQ container111
• 500–550kg bags: 20–22mt in 40’HQ container111

During transportation, it must be kept away from oxidants, edible chemicals, and heat sources. Protection from sunlight, rain, and high temperatures is critical to maintaining its quality.

Storage Guidelines

1. Store in a cool, ventilated, and dry warehouse. Maintain a temperature below 25°C and humidity below 75%.
2. Seal packaging tightly to prevent moisture absorption. Avoid prolonged exposure to sunlight or air to prevent oxidation.
3. Isolate from acids, alkalis, strong oxidants (e.g., potassium nitrate), and reducing agents to prevent degradation.
