What does decolorizer mean?
A decolorizer is a substance or chemical product that removes color from another material. It may be used in laboratories and manufacturing, in textile and paper processing, in hair bleaching, or in household products intended to lift dyes and stains. Depending on the material and formulation, a decolorizer may dissolve a pigment, neutralize a colored compound, or oxidize chromophores so that they no longer produce visible color. The term is most common in American English, although British English also uses it and often spells it decolouriser. In commercial contexts, the word tends to suggest a controlled chemical process rather than a simple physical cleaning action. When it refers to a product, a decolorizer is usually named according to its application, such as a fabric, hair, paper, or wastewater decolorizer. Its meaning is therefore broader than that of bleach in some specialist settings, though the two terms overlap substantially in ordinary usage.

Where does decolorizer come from?

British English commonly employs the corresponding spellings decolourise and decolouriser, with colour reflecting the traditional British spelling.
