Zinc oxide particle, zinc oxide powder and use of same

摘要

Zinc oxide particle with an average particle size of 5-100 nm, comprises a core having a carbon containing residue with a carbon content of 0.2-4 wt.% or greater than 1 to 4 wt.%, relative to zinc oxide particle and with an elemental carbon content of greater than 0.1 wt.% relative to zinc oxide particle or an elemental carbon content of greater than 0.1 wt.% relative to the core, where the carbon is present in non-organically bound form. An independent claim is included for a dispersion comprising the zinc oxide particles, where the zinc oxide particles having an average secondary particle size of 5-100 nm, preferably 10-30 nm. ACTIVITY : Antibacterial; Antiinflammatory. No biological data given. MECHANISM OF ACTION : None given.
