5-AMINO-6-CHLORO-O-CRESOL

Description

5-Amino-6-chloro-o-cresol is a synthetic compound used in hair dye formulations, primarily as a coupler for oxidative hair coloring. This molecule belongs to the class of aminophenols and has a chemical structure that allows it to participate in color-forming reactions when combined with oxidizing agents and primary intermediates.

The compound features an amino group (-NH2) at the 5-position, a chlorine atom at the 6-position, and a methyl group (-CH3) at the 2-position of the phenol ring. This specific arrangement of functional groups contributes to its ability to produce a range of color shades, particularly in the brown to black spectrum.

In hair dye formulations, 5-amino-6-chloro-o-cresol reacts with oxidizing agents like hydrogen peroxide and primary intermediates such as p-phenylenediamine to create larger, colored molecules that adhere to the hair shaft. The resulting dye is semi-permanent to permanent, depending on the specific formulation and application method.

While effective for coloring, this ingredient requires careful handling due to its potential for skin sensitization. Proper patch testing and following manufacturer guidelines are essential to minimize the risk of adverse reactions when using products containing this compound.
