Abstract
The invention relates to an oral care composition with antiplaque agents. The antiplaque agents are complexes of divalent copper, zinc, iron or tin, or trivalent iron with a specific class of cyclic .alpha.-hydroxyketones. A typical example is the copper (II)-ethylmaltol complex. These complexes are more active antiplaque agents that e.g. copper-hinokitiol complexes.
