PYROGALLOL

Description

Pyrogallol, also known as 1,2,3-trihydroxybenzene, is a potent antioxidant compound derived from gallic acid. This organic molecule has a long history in cosmetic and pharmaceutical applications, particularly in hair dye formulations. Pyrogallol's chemical structure consists of a benzene ring with three adjacent hydroxyl groups, giving it unique properties and reactivity.

In haircare, pyrogallol functions as a powerful oxidative dye precursor, capable of producing deep, long-lasting color when combined with other dye intermediates and an oxidizing agent. It is particularly effective in creating dark brown and black hair shades. The compound's ability to penetrate the hair shaft and form stable color molecules contributes to its efficacy in permanent hair coloring systems.

However, pyrogallol's use requires careful formulation due to its potential for skin sensitization and irritation. Its reactivity with oxygen can also lead to color instability if not properly stabilized in product formulations. Additionally, pyrogallol exhibits some antimicrobial properties, which may provide secondary benefits in hair dye products.

When used in controlled concentrations and appropriate formulations, pyrogallol remains a valuable ingredient in professional hair coloring systems, offering intense, durable color results.
