TETRABROMOPHENOL BLUE
Description
Tetrabromophenol Blue is a synthetic compound used in certain cosmetic and personal care formulations, primarily as a pH indicator and colorant. This water-soluble dye belongs to the family of halogenated triarylmethane dyes and exhibits color-changing properties in response to pH variations. In skincare and haircare products, Tetrabromophenol Blue serves as a visual indicator of product efficacy and application uniformity.
The ingredient transitions from yellow in acidic conditions to blue in alkaline environments, with the color change occurring around pH 3.0 to 4.6. This property makes it valuable in formulations where pH monitoring is crucial, such as in hair dyes, facial masks, and pH-balancing skincare products. Tetrabromophenol Blue's stability in various cosmetic bases and its low risk of skin irritation contribute to its utility in personal care applications.
While not directly beneficial to skin or hair health, Tetrabromophenol Blue enhances user experience by providing visual feedback. Its use is regulated in cosmetics, with concentration limits set by regulatory bodies to ensure product safety. Formulators must consider potential interactions with other ingredients and the desired pH range when incorporating this compound into skincare or haircare products.
