BROMPHENOL BLUE

Description

Bromphenol blue is a synthetic organic compound widely used as a pH indicator in various applications, including skincare formulations. This triarylmethane dye exhibits a distinctive color change from yellow to blue as pH increases from 3.0 to 4.6, making it valuable for monitoring acidity levels in cosmetic products. In skincare, bromphenol blue serves primarily as a diagnostic tool rather than an active ingredient with direct skin benefits.

Its molecular structure consists of a central carbon atom bonded to three phenol rings, two of which are brominated. This configuration contributes to its pH-sensitive properties and stability in various formulations. Bromphenol blue is water-soluble and compatible with many cosmetic bases, allowing for easy incorporation into a range of products such as cleansers, toners, and pH-balancing solutions.

While generally considered safe for topical use in low concentrations, bromphenol blue is not intended for prolonged skin contact or ingestion. Its primary function in skincare is to ensure product efficacy and safety by confirming appropriate pH levels, which is crucial for maintaining skin barrier function and optimizing the performance of other active ingredients in formulations.
