Description

Acid Blue 9 Aluminum Lake is a stable, insoluble pigment derived from the water-soluble dye FD&C Blue No. 1 (Brilliant Blue FCF). This product matters for industries requiring vibrant, non-migrating blue coloration in dry or non-aqueous systems where the dye form is unsuitable. It is primarily needed by manufacturers in the pharmaceutical, cosmetic, and food supplement sectors for applications like tablet coating, decorative cosmetics, and colored food packaging.

Application

• Pharmaceutical tablet and capsule coating for brand identification and product differentiation.
• Coloration of decorative cosmetics, including pressed powders, eye shadows, and blushes.
• Pigment for food-contact materials and packaging inks.
• Colorant for dietary supplement tablets and hard-shell capsules.
• Industrial applications in plastics and masterbatch where a stable blue pigment is required.
• Manufacturing of artists' colors and specialty inks.
