FD&C Yellow 5 Al Lake powder color (20 g)

FD&C Yellow 5 Al Lake/L01-0535/0525/0516

FD&C Yellow 5 Al Lake (also known as Tartrazine Aluminum Lake) is a specific form of FD&C Yellow No. 5 (a synthetic colorant) that has been combined with aluminum hydroxide to form a lake pigment. This transformation makes the pigment water-insoluble, which is useful for certain applications like dry foods, coatings, or cosmetic formulations. Below is a detailed breakdown of this colorant.

Full Description of FD&C Yellow 5 Al Lake

• Colorant Name: FD&C Yellow 5 Al Lake (Tartrazine Aluminum Lake)
• Chemical Composition:
  • The base colorant is FD&C Yellow No. 5, commonly known as Tartrazine (C.I. 19140).
  • It is chemically modified by combining FD&C Yellow 5 with aluminum hydroxide to form the lake pigment. This modification renders the pigment insoluble in water but still capable of imparting color to a variety of applications.
• Lake Form: The aluminum lake form is used when an insoluble colorant is required, which is particularly useful in food products that are dry or coated (such as powdered products or tablet coatings) or for cosmetics.

Appearance

• Color: The lake pigment has a bright yellow to golden yellow color, similar to the water-soluble FD&C Yellow No. 5, but with the distinct properties of an insoluble pigment.

Percentage and Usage Rate

• Usage Rate:
  • As with all color additives, the usage rate is regulated by authorities like the FDA in the United States, and usage limits are based on safety considerations for different product categories (food, cosmetics, pharmaceuticals).
  • For cosmetics and personal care products, the concentration is usually less than 0.1%, but formulations must comply with regulations for cosmetic safety.
• Regulatory Limitations:
  • The FDA permits the use of FD&C Yellow No. 5 (and its lake form) in food, drugs, and cosmetics with specific limits to ensure safety.
  • In cosmetics, the FDA has approved its use in various products, including eye makeup, creams, and shampoos, within regulated concentration limits.

Applications

• Cosmetics: It is used in products such as:
  • Eye makeup (eyeshadow, eyeliners)
  • Face products (blushes, foundations, powders)
  • Hair care products (shampoos, conditioners).

Important Notes

• Insolubility: The lake form of FD&C Yellow 5 is insoluble in water, which makes it ideal for applications where a dry or stable pigment is needed
• Stability: FD&C Yellow 5 Al Lake is generally more stable than the water-soluble form, FD&C Yellow No. 5, and is less affected by light and pH changes. This makes it suitable for a variety of formulations that require long shelf life or exposure to different environmental conditions.

Safety Considerations

• Allergic Reactions: Tartrazine (FD&C Yellow 5) has been linked to allergic reactions in sensitive individuals, such as asthma, urticaria (hives), and hyperactivity in children. As a result, in some countries, foods containing this dye may be required to carry a warning label.
• Regulatory Compliance: Always check the relevant regulations for the market in which you're selling products to ensure you're using the correct concentration and adhering to all safety standards.

Summary

• Color: Bright yellow/golden yellow.
• Usage Rate: Typically 0.01% to 0.1% (w/w) depending on the application (food, cosmetics, etc.).
• Applications: Commonly used in foods, beverages, cosmetics, and pharmaceuticals (especially tablets and capsules).
• Stability: More stable than the water-soluble form.
• Regulation: Approved by the FDA for use in food, drugs, and cosmetics, but subject to concentration limits.
