Abstract

The invention relates to a biocidal composition which can be added to materials which can be attacked by harmful micro-organisms, containing pyrithione as a biocidal active ingredient. The biocidal composition is characterised in that it contains 2-alkyl isothiazoline-3-one as another biocidally active ingredient. The active ingredients of the biocidal composition behave synergistically and are ideally suitable for controlling bacteria, fungus and algae.
