ACID ORANGE 7
Description
Acid Orange 7, also known as CI 15510 or D&C Orange No. 4, is a synthetic azo dye commonly used in cosmetic and personal care products. This water-soluble colorant imparts a vibrant orange hue to various formulations, including shampoos, hair dyes, and other haircare products. Its molecular structure allows for excellent color stability and uniformity in application.
In haircare formulations, Acid Orange 7 is primarily utilized for its coloring properties, providing temporary or semi-permanent color to hair strands. It is particularly effective in creating warm, copper-like tones and enhancing red or auburn shades. The dye's affinity for hair proteins enables it to adhere to the hair shaft, resulting in longer-lasting color effects compared to some other temporary colorants.
While Acid Orange 7 is approved for use in cosmetics by regulatory bodies in many countries, it is essential to note that some individuals may experience sensitivity or allergic reactions. As with any hair dye, patch testing is recommended before full application. Additionally, proper formulation and pH adjustment are crucial to ensure optimal color development and minimize potential irritation.
