alvejante

Alvejante is a Portuguese word that translates to "bleach" in English. It refers to a substance used to remove stains and discolorations, typically from fabrics and other materials. The most common type of alvejante is chlorine-based, which works by oxidizing colored compounds, breaking them down into colorless substances. Sodium hypochlorite is the active ingredient in most household chlorine bleaches.

Alvejantes are widely used in laundry to whiten clothes and remove tough stains like grass, wine, or ink. They can also be used for sanitizing surfaces in homes, hospitals, and other settings, as the oxidizing action also kills bacteria, viruses, and fungi. However, it's important to note that alvejante should be used with caution. It can damage certain fabrics, including wool, silk, and spandex, and can cause skin and eye irritation. Proper ventilation is also recommended when using chlorine-based alvejantes due to the release of fumes.

In addition to chlorine-based products, there are also oxygen-based alvejantes. These typically contain hydrogen peroxide or sodium percarbonate and are generally considered gentler on fabrics and less harsh in terms of fumes. They are effective at removing many common stains and are often preferred for colored fabrics where chlorine bleach might cause fading. Regardless of the type, always follow the product instructions for safe and effective use.
