Brief Definition

Sodium persulfate is a strong oxidizing agent frequently used in hair bleaches and technical applications. In cosmetics, sodium persulfate is primarily used for lightening hair.

What is Sodium Persulfate?

Sodium persulfate, also known as sodium peroxydisulfate, is an inorganic salt with a strong oxidizing effect. As an oxidizing agent, sodium persulfate is mainly used in bleaching powders and hair coloring products to chemically lighten color pigments in the hair. The substance reacts in combination with hydrogen peroxide and enables intensive lightening processes.

In the INCI declaration, the ingredient appears as Sodium Persulfate. In addition to cosmetic applications, sodium persulfate is also used in polymer chemistry, cleaning products, and technical processes. Due to its reactive properties, sodium persulfate can cause skin or respiratory irritation in sensitive individuals, which is why it is clearly regulated in cosmetic products. Its use is predominantly in professional hair treatments or special bleaching systems.
