Description

Food Yellow No. 4 Aluminum Lake is an insoluble pigment produced by adsorbing the water-soluble dye Tartrazine onto an alumina substrate. This compound is valued for its exceptional stability, providing vibrant, non-bleeding yellow to orange hues in applications where water or oil migration is a concern. It is primarily required by manufacturers in the food, pharmaceutical, and cosmetic industries seeking compliant and reliable colorants for coated tablets, confectionery, and decorative coatings.

Application

• Coloring sugar-coated and film-coated pharmaceutical tablets and capsules.
• Providing stable color in hard-panned confectionery products like coated chocolates and dragees.
• Use in decorative food applications, including printing inks for cookies and cake decorations.
• Coloration of cosmetic products such as lipsticks, blushes, and pressed powders.
• Manufacturing of plastic and polymer products where a non-migrating colorant is required.
• As a colorant for pet food and veterinary medicinal products.
