ACID YELLOW 1

Description

Acid Yellow 1, also known as Flavianic Acid or C.I. 10316, is a synthetic dye widely used in the cosmetic and personal care industry, particularly in haircare products. This water-soluble compound belongs to the azo dye family and is characterized by its bright yellow color. In haircare formulations, Acid Yellow 1 serves as a semi-permanent colorant, providing vibrant yellow hues to hair dyes and tinting products.

The dye's molecular structure allows it to penetrate the hair shaft, adhering to the cortex and providing longer-lasting color results compared to temporary dyes. Acid Yellow 1 is often combined with other dyes to create a spectrum of shades, from golden blondes to warm brunettes. Its performance is particularly notable in gray hair coverage and highlighting applications.

While Acid Yellow 1 is generally considered safe for use in cosmetics, it's important to note that some individuals may experience allergic reactions or skin sensitization. As with all hair dyes, patch testing is recommended before full application. Formulators should be aware of regulatory limitations on concentration levels in different regions when incorporating this ingredient into haircare products.
