Description

Food Red No 3 Aluminum Lake is a stable, insoluble pigment derived from the water-soluble dye Erythrosine. This product matters because it provides a vibrant, non-bleeding red color in applications where water or oil migration is a concern. It is primarily needed by manufacturers in the food, pharmaceutical, and cosmetic industries seeking to color dry mixes, coatings, and polymer systems. The compound is also known by its CAS number 12227-78-0.

Application

• Coloring sugar-shelled confectionery, coated tablets, and hard-panned candies.
• Pigmentation of plastic packaging materials and masterbatches for food contact.
• Manufacturing of decorative cosmetic products, such as pressed powders and blushes.
• Coloring edible printing inks for cake decorations and food stamps.
• Use in dry food mixes (e.g., dessert powders, drink mixes) where water solubility is undesirable.
• Pigment for pharmaceutical tablet coatings and capsule shells.
• Coloring of pet food and animal feed supplements.
• Industrial applications requiring a stable, light-fast red pigment in non-aqueous systems.
