Technical Document

Brief Overview

Sodium perborate (or PBS) is a white amorphous powder, which has two hydrate forms: the monohydrate (NaBO₃·H₂O) or the tetrahydrate (NaBO₃·4H₂O). The most frequently available form of the compound, the tetraborate, is a white crystalline solid with a salty taste that melts at 63°C (145°F) and loses its water of hydration when heated above 130°C (270°F). When dissolved in water, all forms of sodium tetraborate decompose to yield hydrogen peroxide (H₂O₂) and sodium borate (Na₂B₄O₇).

The formation of hydrogen peroxide, which is itself unstable and breaks down to release nascent oxygen (O), makes sodium tetraborate an excellent source of 'active' oxygen. The terms nascent and active refer to individual atoms of oxygen that have a strong tendency to react with other elements and compounds. Since sodium tetraborate is more stable than hydrogen peroxide, it can be used for the same purposes as the peroxide, but is safer and easier to handle. The most common applications of sodium tetraborate are in detergents, bleaches, hair care products, and disinfectants.
