The invention concerns the use of a film-forming titanium dioxide dispersion
for cleaning and disinfecting surfaces exposed to light, by depositing a film of
titanium dioxide nanoparticles on said surfaces, the continuous phase of said dispersion
comprising water and/or at least an alcohol with boiling point at less than 120
C., said dispersion having, when it comprises water, a pH different by at least
1 unit of the value of the titanium dioxide isoelectric pH in said dispersion.
The invention also concerns a film-forming titanium dioxide dispersion further
comprises a film-forming polymer. The invention further concerns a method for cleaning
and disinfecting surfaces exposed to light which consists in depositing and then
drying on said surfaces a titanium oxide film-forming dispersion.
