Precision Color. Zero Dust.

Bond of Colours supplies Indigo Carmine Granular (FD&C Blue No. 2), a specialized “Dust-Free” synthetic colorant for manufacturers who demand a cleaner production environment. Unlike fine powders that create airborne mess, our granular form flows freely, dissolves rapidly, and significantly reduces cross-contamination risks in your facility.

This deep royal blue dye (also known as Indigotine) is sourced exclusively from FDA-audited facilities, ensuring every batch meets the strict purity standards of 21 CFR Part 74 for food, drug, and cosmetic use.

Key Applications

• Confectionery & Baking: Delivers vibrant blue shades in candies, icings, and baked goods without the mess of powder.
• Beverages: Excellent solubility for clear and opaque drink formulations.
• Pharmaceuticals: Widely used for tablet coatings and capsule identification.
• Industrial Indicators: Functions as a pH indicator (blue at pH 11.4, yellow at pH 13.0) and in medical diagnostic dyes.

Why Choose Granular over Powder?

• Worker Safety: Drastically reduces airborne particulates, improving air quality for operators.
• Cleanliness: Less cleanup required between batches; “Flows like sugar, dissolves like ink.”

Common Questions (FAQ)

Q: Is Indigo Carmine Granular suitable for acidic beverages? A: Yes. Indigo Carmine (Blue 2) has very good stability in acidic environments (low pH), making it excellent for fruit-flavored beverages and sour candies.

Q: Does the granular form take longer to dissolve than powder? A: Marginally. While powder dissolves instantly, our granular form is designed to break down rapidly in water with standard agitation, ensuring no “specks” remain in the final product.

Q: Is this product natural or synthetic? A: This is a Synthetic (Artificial) colorant. While “Indigo” historically came from plants, FD&C Blue No. 2 is synthetically produced to ensure the high purity and safety required by the FDA.
