Patent granted for “Plasma Activated Water”

Our patent application for "Plasma Activated Water" was approved in Europe (EP3411085). The patent concerns the production of plasma-activated water for the disinfection of objects, in particular dentures and the treatment of teeth.

Chemical solutions are typically used to clean dentures, but they contain comparatively high concentrations of chemicals. The problem, however, is that these solutions are not suitable for consumption and are harmful if consumed by mistake – similar to toothpaste, which at best should not be swallowed.

Furthermore, for the bleaching of dentures and/or teeth, mostly concentrated hydrogen peroxide is used that is far above the EU limit for non-professional tooth bleaching. Here, plasma-activated water offers a safe, waste-free alternative. The patent protection gained, hence should strengthen terraplasma’s position in plasma technology even more.
