What is sodium persulfate?

Sodium persulfate is a white, crystalline compound that is commonly used as a strong oxidizing agent in various industrial applications. It has the chemical formula Na2S2O8 and is highly soluble in water.

Some common uses of sodium persulfate include as a bleach and a hair lightening agent in the textile and cosmetics industries, as a chemical initiator in polymerization reactions, and as an etchant in the production of printed circuit boards.

Sodium persulfate is considered a more environmentally friendly alternative to traditional oxidizing agents such as hydrogen peroxide, as it does not produce harmful byproducts when used in water treatment and waste disposal processes.

However, sodium persulfate is a strong irritant to the skin, eyes, and respiratory system, so proper safety precautions must be taken when handling this compound.
