YELLOW 11

Description

Yellow 11 is a synthetic azo dye used in various cosmetic and personal care products to impart a yellow color. This water-soluble colorant is approved by the FDA for use in cosmetics and drugs, including those applied to mucous membranes. Its chemical structure consists of a diazo compound with aromatic rings, which contributes to its stability and color-fastness.

In skincare formulations, Yellow 11 is often employed in small quantities to adjust the hue of products such as lotions, creams, and sunscreens. It can help create a more aesthetically pleasing appearance or mask the natural color of other ingredients. The dye is particularly useful in color-correcting cosmetics, where it can neutralize purple or blue tones in the skin.

While generally considered safe for topical use, some individuals may experience sensitivity or allergic reactions to Yellow 11. As with any synthetic colorant, patch testing is recommended for those with sensitive skin or a history of allergies. Formulators should be aware of regulatory limits on its concentration in different product types and adhere to good manufacturing practices to ensure product safety and efficacy.
