ACID VIOLET 9

Description

Acid Violet 9, also known as CI 45190, is a synthetic dye belonging to the triarylmethane family of colorants. This water-soluble compound is primarily utilized in the cosmetic and personal care industry, particularly in haircare formulations. Its vibrant purple hue makes it a popular choice for toning and color-correcting products designed for blonde, gray, or silver hair.

In haircare applications, Acid Violet 9 effectively neutralizes unwanted yellow or brassy tones, imparting a cooler, more desirable shade to treated hair. Its molecular structure allows for temporary coloration without penetrating the hair shaft, making it suitable for frequent use in maintenance routines. The dye exhibits good stability in various pH environments and demonstrates compatibility with common haircare ingredients.

While primarily used in hair products, Acid Violet 9 may also be incorporated into select skincare formulations for color adjustment purposes. However, its application in skincare is limited due to potential skin staining concerns. As with all colorants, patch testing is recommended to ensure individual tolerance. Formulators should adhere to regulatory guidelines regarding concentration limits and usage restrictions when incorporating Acid Violet 9 into product formulations.
