Basic Violet 14

What is Basic Violet 14?

Basic Violet 14, identified as CI 42510 and commonly known as Rhodamine B, is a synthetic xanthene-class dye with a cationic structure that enables strong affinity for hair proteins. Originating from organic chemistry synthesis, it appears as a reddish-violet powder soluble in water and alcohol. In cosmetics, it serves exclusively in hair care formulations, such as semi-permanent and oxidative hair dyes. Functionally, it deposits color directly onto the hair cuticle in direct dye systems or integrates into melanin-altering reactions in permanent dyes, yielding long-lasting violet shades. Its fluorescent trait amplifies color intensity under UV light, aiding visual appeal in styled hair. Regulatory bodies scrutinize its application due to inherent chemical properties influencing absorption and potential bioactivity.
