fehérítéket

Fehérítéket, commonly translated as "bleach" in English, refers to a class of chemical agents used to remove color from materials, primarily textiles and paper. The most common types of bleach are chlorine-based and oxygen-based. Chlorine bleach, such as sodium hypochlorite, works by oxidizing and breaking down colored molecules, rendering them colorless. It is effective at whitening and disinfecting but can be harsh on fabrics and should be used with caution, as it can damage certain materials and produce toxic fumes when mixed with other chemicals.

Oxygen bleach, typically based on hydrogen peroxide or sodium percarbonate, is a gentler alternative. It also works through oxidation but releases oxygen molecules that break down stains and dullness. Oxygen bleaches are generally safer for most fabrics and the environment compared to chlorine bleaches. Both types of bleach are widely used in household laundry for whitening clothes and removing stains, as well as in industrial processes for paper and pulp manufacturing and water purification. Proper handling and dilution are crucial when using any type of bleach to ensure safety and effectiveness.
