Abstract
The present disclosure relates to a photocatalytic composition comprising photocatalytic titanium dioxide particles being dispersed in a continuous phase, and at least one anti-photogreying additive, wherein said at least one anti-photogreying additive is adapted to limit photogreying of said titanium dioxide particles while the photocatalytic activity of said titanium dioxide particles is maintained, and wherein the photo greying index (ΔL) of said composition is less than 6.
