2-METHYL-5-HYDROXYETHYLAMINOPHENOL

Description

2-Methyl-5-hydroxyethylaminophenol is a synthetic hair dye intermediate primarily used in oxidative hair coloring formulations. This compound belongs to the class of aromatic amines and is characterized by its ability to produce brown to black shades when combined with an oxidizing agent. Its chemical structure consists of a phenol ring substituted with a methylamine group and a hydroxyethyl group.

In hair coloring applications, 2-methyl-5-hydroxyethylaminophenol acts as a coupling agent, reacting with primary intermediates to form larger, color-producing molecules within the hair shaft. This interaction results in long-lasting, vibrant color that penetrates the hair cuticle. The compound's molecular size allows for efficient diffusion into the hair fiber, ensuring even color distribution.

While effective for hair coloration, this ingredient requires careful handling due to its potential for skin sensitization. Manufacturers typically use it in concentrations ranging from 0.1% to 1.5% in finished products. It is essential to conduct patch tests before use and adhere to recommended exposure limits to minimize the risk of adverse reactions. Safety assessments have shown that when used as directed in hair dye formulations, 2-methyl-5-hydroxyethylaminophenol poses minimal risk to consumers.
