2-AMINO-4-HYDROXYETHYLAMINOANISOLE

Description

2-Amino-4-hydroxyethylaminoanisole is a synthetic hair dye ingredient primarily used in oxidative hair coloring formulations. This compound belongs to the class of para-substituted aminophenols and acts as a precursor in the development of hair color. When combined with an oxidizing agent, typically hydrogen peroxide, it produces vibrant, long-lasting color results.

The molecule's structure allows it to penetrate the hair shaft effectively, where it reacts with other dye precursors to form larger, colorfast pigment molecules. This process results in a permanent color change within the hair fiber. 2-Amino-4-hydroxyethylaminoanisole is particularly effective in creating warm brown to reddish-brown shades, depending on the other components in the dye formulation.

Safety assessments have shown that when used as directed in hair dye products, this ingredient poses a low risk of skin irritation or sensitization. However, as with all hair dyes, patch testing is recommended before use to identify potential allergic reactions. The compound is regulated for use in hair dye formulations by cosmetic authorities in various countries, including the European Union, where its maximum concentration in ready-to-use preparations is set at 1.5%.
