SOLVENT ORANGE 1

Description

Solvent Orange 1, also known as CI 11920 or 1-phenylazo-2-naphthol, is a synthetic azo dye commonly used in cosmetic and personal care formulations. This oil-soluble colorant imparts a vibrant orange hue to various products, including hair dyes, nail polishes, and some skincare items. Its molecular structure allows for excellent solubility in oils and organic solvents, making it a versatile choice for oil-based formulations.

In haircare applications, Solvent Orange 1 is primarily utilized in temporary and semi-permanent hair coloring products. It provides a warm, golden-orange tone that can enhance natural hair color or create bold, fashion-forward looks. The dye's ability to adhere to the hair shaft without penetrating deeply allows for easy washout and color changeability.

While effective as a colorant, formulators should be aware of potential sensitivities in some individuals. Patch testing is recommended before widespread use. Additionally, due to concerns about azo dyes, some regulatory bodies have imposed restrictions on its concentration in cosmetic products. Formulators must adhere to regional guidelines when incorporating Solvent Orange 1 into their products to ensure safety and compliance.
