CI 21230

Description

CI 21230, also known as Brilliant Yellow 2, is a synthetic yellow dye used in various cosmetic and personal care products. This water-soluble colorant belongs to the azo dye family and is characterized by its bright, vibrant yellow hue. CI 21230 is approved for use in cosmetics and toiletries in many countries, including those in the European Union, where it is listed in Annex IV of the EU Cosmetics Regulation.

The dye is primarily utilized in products such as soaps, shampoos, bath products, and decorative cosmetics. Its stability in various formulations and resistance to light make it a popular choice for manufacturers seeking long-lasting color in their products. CI 21230 is often used in combination with other dyes to create specific shades and color effects.

While generally considered safe for use in cosmetics, some individuals may experience skin irritation or allergic reactions to azo dyes. As with any cosmetic ingredient, patch testing is recommended for those with sensitive skin or a history of allergic reactions. It's important to note that CI 21230 is not approved for use in products that come into contact with mucous membranes or in the eye area in some jurisdictions.
