decoloración

Decoloración refers to the process of removing or lightening the color from a substance. This is most commonly discussed in the context of hair coloring, where chemical agents are used to strip the natural pigment from the hair shaft. The primary active ingredient in most hair decolorizing products is hydrogen peroxide, often in combination with an alkali like ammonia. These chemicals break down the melanin, the pigment responsible for hair color.

The extent of decolorization depends on the strength of the product, the duration of application, and the original color and porosity of the hair. Lighter hair colors are achieved with shorter processing times or weaker solutions. Decolorization can also be used on other materials, such as fabrics, to achieve specific aesthetic effects or prepare them for further treatment. In industrial settings, decolorization processes are employed to purify liquids or solids by removing colored impurities. For example, activated carbon is frequently used to decolorize sugar solutions. The exact methods and chemicals used vary widely depending on the material being treated and the desired outcome.
