Brief definition

Ammonium persulfate is a strong oxidizing agent primarily used in hair bleaching products. In cosmetics, ammonium persulfate is used for intensive lightening of hair pigments.

What is Ammonium Persulfate?

Ammonium persulfate, also known as ammonium peroxodisulfate, is an inorganic salt with a strong oxidizing effect. As an oxidizing agent, ammonium persulfate is mainly used in bleaching powders and hair dyes to chemically decompose and lighten natural hair pigments. In combination with hydrogen peroxide, this ingredient enables controlled lightening processes.

In the INCI list, the substance appears as Ammonium Persulfate. In addition to cosmetic applications, ammonium persulfate is also used in technical fields such as polymerization or cleaning. Due to its reactive properties, ammonium persulfate can cause skin irritation or respiratory reactions in sensitive individuals. Therefore, its use in the EU is clearly regulated and often limited to professional applications. As a component of bleaching agents, ammonium persulfate is one of the key active ingredients for strong lightening effects.
