CI 18130

Description

CI 18130, also known as Acid Red 1 or Red 18, is a synthetic azo dye commonly used in cosmetic and personal care products. This water-soluble colorant imparts a vibrant red hue to various formulations, including lipsticks, blushes, and other decorative cosmetics. Its molecular structure allows for excellent color payoff and stability in a wide range of pH levels.

In cosmetic applications, CI 18130 is valued for its ability to create intense, long-lasting color without significant fading. It is often preferred in formulations where a true red shade is desired, as it resists shifting to orange or pink tones. This dye is approved for use in the European Union and many other countries, though restrictions may apply depending on the specific product type and concentration.

While generally considered safe for topical use, some individuals may experience sensitivity or allergic reactions to azo dyes. As with all colorants, patch testing is recommended for those with sensitive skin. Formulators should be aware of regulatory limits and guidelines when incorporating CI 18130 into products, particularly those intended for use around the eye area or on mucous membranes.
