FD&C Blue 1 Al Lake/L01-0115/0111 (20g)

1 Al Lake (also known as Blue 1 Lake, with the chemical name Brilliant Blue FCF Aluminum Lake) is a specific form of FD&C Blue No. 1 (a synthetic colorant) that has been reacted with aluminum hydroxide to form a lake pigment. It is primarily used for coloring food, drugs, and cosmetics. Here's a detailed breakdown of the colorant:

Full Description

• Colorant Name: FD&C Blue 1 Al Lake (Brilliant Blue FCF Aluminum Lake)
• Chemical Composition:
  • The base dye is Brilliant Blue FCF (also known as FD&C Blue No. 1, C.I. 42090).
  • It is chemically modified by combining the dye with aluminum hydroxide, resulting in a water-insoluble pigment.
  The lake form of the dye is typically used when an insoluble colorant is needed in formulations (such as in dry applications, coatings, or for cosmetic use).

Appearance

• Color: The color of the lake pigment is typically a vibrant blue, similar to the original FD&C Blue No. 1, but with different application properties.

Percentage and Usage Rate

• Usage Rate:
  • The usage of FD&C Blue 1 Al Lake is regulated by authorities such as the U.S. Food and Drug Administration (FDA) for food, drugs, and cosmetics..
  • In cosmetics, the concentration can also vary but is often lower than in food products. The FDA allows its use in cosmetic products in concentrations of up to 0.1% or lower, depending on the application.

Applications

• Cosmetics: It is used in products like eye shadows, lotions, creams, lipsticks, and other makeup items..

Regulatory Status

• The FDA has approved the use of FD&C Blue 1 (and its lake form, FD&C Blue 1 Al Lake) in food, drugs, and cosmetics, but usage is subject to strict limits to ensure safety.

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.

Always ensure that the specific product you're developing adheres to the regulations for safe use of colorants in the relevant region (e.g., FDA in the U.S., EFSA in the EU)
