What is FD&C Yellow No. 6 Aluminum Lake?
FD&C Yellow No. 6 Aluminum Lake (CAS No. 15706-26-8) is a synthetic organic colorant approved by the U.S. Food and Drug Administration (FDA) for use in food, drugs, and cosmetics. It is a water-insoluble lake pigment derived from FD&C Yellow No. 6 (Sunset Yellow FCF) by precipitation onto an aluminum hydroxide substrate. This process enhances its stability and disperses properties, making it suitable for a range of pharmaceutical applications, particularly in solid dosage forms like tablets and capsules. The colorant provides a vibrant yellow hue and is utilized to differentiate products, indicate dosage, or improve product aesthetics. Its regulatory status is governed by 21 CFR Part 74.1706 in the United States.
What are the Primary Pharmaceutical Applications?
The primary pharmaceutical applications for FD&C Yellow No. 6 Aluminum Lake involve its use as a colorant in solid oral dosage forms. These include:
- Tablets: Providing distinctive color for identification and branding.
- Capsules: Coloring the capsule shell or the contents within.
- Coatings: Incorporated into film coatings for tablets to enhance visual appeal and patient compliance.
Beyond oral solids, it can also be found in certain topical preparations and pharmaceutical inks used for tablet printing. The choice of FD&C Yellow No. 6 Aluminum Lake is driven by its color intensity, lightfastness, and chemical inertness within typical pharmaceutical formulations.
