SOLVENT YELLOW 18
Description
Solvent Yellow 18, also known as N,N-Diethyl-4-(phenylazo)aniline, is a synthetic azo dye primarily used in haircare formulations. This oil-soluble colorant imparts a vibrant yellow hue to various hair products, including temporary hair dyes, styling gels, and highlighting creams. Its molecular structure allows for efficient penetration into the hair shaft, providing temporary color without causing significant damage to the hair's cuticle.
In haircare applications, Solvent Yellow 18 offers excellent color stability and resistance to fading, making it ideal for short-term color transformations. It is particularly effective in creating warm, golden tones or enhancing existing blonde shades. The dye's solubility in oils and organic solvents enables its incorporation into a wide range of hair product bases, from creams to sprays.
While Solvent Yellow 18 is generally considered safe for cosmetic use, it's important to note that some individuals may experience skin sensitivity or allergic reactions. As with all hair dyes, patch testing is recommended before full application. The ingredient is regulated by cosmetic authorities worldwide, with specific concentration limits set to ensure consumer safety in hair coloring products.
