Oxidation dyes are primarily aromatic compounds and typically a low molecular weight product. This dye belongs to three major chemical families that are listed below:
Aminophenols (amino naphthols)
Phenols or naphthols
Oxidation dyes are used as a very popular colorant material. It forms the basis of the hair dyes. This is because the oxidation dyes has the property to cover up Grey and achieve long lasting results. They give a wide array of color range that includes color enhancement, Grey control and fashion colors. In the context of hair dyes, Oxidation dyes have been found just right for permanent and demi-permanent or semi-permanent applications.
Oxidation base (primary intermediate) and coupler (secondary intermediate). For generating color and ensure best results, it is essential to use at least one type of dye and mix it with a perfect oxidant under alkaline conditions. Oxidation dyes often depend on a solution of dye intermediates like p-phenylenediamine for achieving the perfect colors. This dye has also has an another important ingredient, named Hydrogen Peroxide. To have a lighter and faster result, a higher volume of peroxide should be used.
Keys to Selecting the Right Oxidation Dyes
Few factors that should be considered while selecting the right kind of Oxidation dyes are:
A thorough understanding of the oxidative condensation process.
For hair dyes, considerable experience with a fair number of practical trials. This should take into account various kinds of hair type.
A delicate balance among:
Nature of the dye precursors
Quantity of ammonium used
Limitation of Oxidation Dyes
This dye is harmful for hair structure. To repair hair damages that happens due to high alkalinity and strong oxidizing agent, there is a need of another product.
