The components that makeup it are hydrogen peroxide, ammonia, and methanol. Its manufacturing process includes the following chemical reactions: hydrolysis, oxidation, and synthesis.

In addition to having a colourless appearance, it also has properties such as stability in air and water. These compounds react with hair proteins to form larger molecules called hair colour pigments. Hair colourants intermediates are organic compounds that are used to make hair dyes.

Many of the chemicals are complex derivatives of phenols, aromatic amines, or thiazoles. They are derived from coal tar, wood tar, petroleum distillates, and other sources. It is a water-soluble liquid paint. They come in the form of liquids, creams, gels, lotions and pastes. 


Hair colourants intermediates are isolated from natural sources or are prepared synthetically.

These are widely used for the preparation of various dyes, pigments, etc. Due to their fastness to light, light fastness, high covering power, high elongation, high flexibility, good solubility, etc., they are used as intermediates in dyes, pigments, paints, etc.
