A detergent comprising: a) 0.001% to 40% w/v of a bactericidally active water-insoluble cationic compound in its salt form wherein the counterion anion has at least one of the following properties: 1) can generate a water-insoluble salt form, by water-insoluble we mean that less than 10% w/v dissolves in deionised water at 20° C., preferably less than 1% w/v; 2) has a MW of less than 300, (preferably less than 200) but greater than 50 (preferably greater than 75), 3) the dissociation constant (Kd) of the salt is less than 10<SUP>-3</SUP>, preferably less than 10<SUP>-6</SUP>; b) 0.001 to 40% w/v of an anionic surfactant; and c) up to 98% w/v of water.
