Sodium persulfate

Sodium persulfate is a white, crystalline, odourless salt. It is used as initiator for the polymerisation of monomers and as a strong oxidizing agent in many application.

It has the particular advantage of being almost non-hygroscopic, of having a particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.

SPS is also a kind of oxidizing agent: (1) Used in cleaning and pickling of metal surfaces. (2) Used in accelerated curing of low formaldehyde adhesives. (3) Used in modification of starch, production of binders and coating materials. (4) Desizing agent and bleach activator. (5) An essential component of bleaching formulations for hair cosmetics.
