ABSTRACT:
Cleaning compositions including a photocatalytic material and a sensitiser employ a photocatalytic material and a sensitiser at a locus, for example on a surface. The residue combats soils and/or undesired microorganisms at the locus. The addition of a monohydric or polyhydric alcohol, preferably having humectant properties, gives benefits in terms of smear avoidance on application and soil removal thereafter.
