Abstract (en)
[origin: WO2021053379A1] A sanitization composition is provided for sanitization- purification of surfaces and environments, comprising particles of titanium dioxide dispersed in water to form an aqueous colloidal dispersion and having pre-established dimensions, preferably in the anatase crystal form. A part of the titanium dioxide is doped, in particular with nitrogen. The composition further comprising at least one optical brightener which, struck by ultraviolet radiation, is able to re-emit visible light by fluorescence.
