NaBO3H2O

NaBO3H2O, commonly written NaBO3·H2O, is sodium perborate monohydrate, an inorganic boron‑oxygen salt used as an oxidizing bleaching agent. It is the monohydrate form of sodium perborate and consists of a perborate anion paired with a sodium cation. In solid form it appears as a white crystalline substance and dissolves readily in water; in aqueous solution it acts as a source of hydrogen peroxide, enabling mild bleaching.

Industrial production involves oxidation of borate species with hydrogen peroxide under alkaline conditions, followed by crystallization to yield the monohydrate (and related hydrates). The hydrate form is common because it provides storage stability and controlled release characteristics.

Properties include moderate chemical stability as a solid and a strong oxidizing tendency in solution. It decomposes on heating, releasing oxygen, and the aqueous solution is typically alkaline due to borate. It is highly soluble in water.

Applications are dominated by its use as an oxygen bleach in laundry detergents and other cleaning products, where it releases peroxide gradually at ambient temperatures. It has also been used in certain sanitation and cosmetic-related contexts, though substitutes such as hydrogen peroxide are common.

Safety and handling: NaBO3H2O is an oxidizer and can intensify fires; avoid contact with acids, reducing agents, and flammable materials. Use protective equipment and store in a cool, dry place in a sealed container. If contact occurs, wash with water; seek medical advice for exposure.

Environmental notes: Borate-containing waste should be managed according to local regulations, as elevated boron levels can affect aquatic life.
