CI 18690

Description

CI 18690, also known as Acid Yellow 23 or Tartrazine, is a synthetic yellow azo dye commonly used in cosmetics and personal care products. This water-soluble colorant is approved by the FDA for use in drugs and cosmetics, including those applied to the area of the eye. In skincare formulations, CI 18690 is primarily utilized to impart a yellow hue to various products such as lotions, creams, and bath preparations.

The ingredient is known for its stability across a wide pH range and resistance to light, making it suitable for long-lasting color in formulations. CI 18690 is often chosen for its bright, clear yellow shade and its ability to blend well with other colorants to create custom hues. While generally considered safe for use in cosmetics, some individuals may experience allergic reactions or skin sensitization to azo dyes.

Formulators should be aware of regulatory limits on the concentration of CI 18690 in different product types. In the European Union, it is permitted in all cosmetics except those used on mucous membranes. When incorporating CI 18690 into skincare products, it's essential to consider potential interactions with other ingredients and conduct appropriate stability and safety testing to ensure product integrity and consumer safety.
