ACID BROWN 13

Description

Acid Brown 13, also known as CI 10410, is a synthetic dye commonly used in hair coloring products. This azo dye belongs to the acid dye class and is characterized by its ability to impart a rich brown hue to hair fibers. The molecule's structure allows it to penetrate the hair shaft and bond with keratin proteins, resulting in long-lasting color.

In hair formulations, Acid Brown 13 is often combined with other dyes to create a wide range of brown shades, from light chestnut to deep espresso. Its stability in acidic environments makes it particularly suitable for use in permanent and semi-permanent hair color products. The dye demonstrates good color fastness, resisting fading from washing and environmental factors.

While effective for coloring purposes, it's important to note that some individuals may experience allergic reactions to Acid Brown 13. Patch testing is recommended before use. Additionally, this dye is not approved for use in cosmetics intended for application around the eye area in some regions due to potential sensitization concerns. When formulating with Acid Brown 13, careful consideration of concentration levels and regulatory guidelines is essential to ensure product safety and efficacy.
