CI 21108

Description

CI 21108, also known as Acid Red 14, is a synthetic colorant used in various cosmetic and personal care products. This water-soluble dye belongs to the azo dye family and is characterized by its vibrant red hue. It is primarily utilized in color cosmetics, including lipsticks, blushes, and nail polishes, to impart a rich, warm red tone.

The colorant is approved by the FDA for use in cosmetics and is considered safe when used as directed. It is particularly valued for its stability and resistance to fading, ensuring long-lasting color in formulations. CI 21108 is often preferred in products designed for extended wear or those exposed to environmental factors like sunlight and humidity.

While generally well-tolerated, some individuals may experience sensitivity to azo dyes. As with any colorant, patch testing is recommended for those with sensitive skin or a history of allergic reactions. Formulators should be aware of concentration limits set by regulatory bodies and adhere to good manufacturing practices when incorporating CI 21108 into cosmetic products. Its use is restricted in products applied near the eye area in some jurisdictions, so regional regulations should be consulted during product development.
