CI 16255

Description

CI 16255, also known as Red 33 or Acid Red 33, is a synthetic colorant widely used in cosmetics and personal care products. This water-soluble dye belongs to the xanthene class of compounds and imparts a vibrant red to pink hue to various formulations. Its molecular structure allows for excellent stability across a wide pH range, making it versatile for use in both acidic and alkaline products.

In skincare and cosmetic applications, CI 16255 is primarily utilized in color cosmetics, including lipsticks, blushes, and nail polishes. It also finds use in hair dyes and some skincare products where a pink or reddish tint is desired. The colorant is approved by the FDA for use in cosmetics and personal care items, including those applied to the lip area and products that may come into contact with mucous membranes.

While generally considered safe for topical use, some individuals may experience sensitivity or allergic reactions to synthetic dyes. As with any colorant, patch testing is recommended for those with sensitive skin or a history of allergic reactions. Formulators should adhere to regulatory guidelines regarding maximum concentration limits in different product types to ensure safety and compliance.
