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.
