Important Notes:
- Insolubility: Being a "lake" form, FD&C Blue 1 Al Lake is insoluble in water, which makes it ideal for dry applications and coating purposes (like in candies or coatings for pills).
- Stability: FD&C Blue 1 Al Lake tends to be more stable in light, heat, and pH variations compared to its water-soluble counterpart (FD&C Blue 1), making it preferable in products that require stability during storage.
