decolorat

Decolorat is a Romanian adjective and past participle meaning decolorized or bleached. It is the masculine singular form; the feminine singular is decolorată. The term derives from the verb a decolora, built with the prefix de- and the root color, and is used to describe substances, materials, or states from which color has been removed. In everyday language it commonly appears in phrases such as părul decolorat (bleached hair), materialul decolorat (the decolorized fabric), or soluția decolorată (the color-removed solution).

In chemistry and industry, decolorarea refers to the process of removing color from a solution or material. Decolorarea methods include oxidation with bleaching agents (for example hydrogen peroxide or sodium hypochlorite) and adsorption using activated carbon or resins. The chosen method depends on the substrate and the desired shade. In textiles and paper production, decolorarea is a preparatory step before dyeing or finishing.

Usage notes: as an adjective, decolorat agrees with gender and number of the noun it describes; as a past participle used with auxiliary verbs, it indicates the completion of the decoloring action. The term is closely related to decolorare (the act of decolorizing) and to related compounds such as decoloranți or bleaching agents.
