Abstract: A biocidal composition comprising a combination of at least two biocidal components, in which 1,2-benzisothiazolin-3-one and/or N-methyl-1,2-benzisothiazolin-3-one and/or N-methyl-1,2-benzisothiazolin-3-one are used as one component and silver in the form of, for example, organic or inorganic silver salts, colloidal or nanoparticulate silver or silver oxide is used as the other component, has a broad spectrum of activity against diverse bacteria and fingi.

Abstract: A biocide composition is disclosed as an additive to substances susceptible to infestation by harmful organisms, containing 2-methylisothiazolin-3-one as a biocidal agent. The composition is characterized in that it contains 3-iodo-2-propynyl-N-butylcarbamate as a farther biocidal agent, with the exception of biocide compositions containing 5-chloro-2-methylisothiazolin-3-one. In comparison to its individual constituents, the composition provided by the invention presents a synergistic biocidal action.

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.

Abstract: The invention relates to a coating material for protection against microorganisum invasion on surfaces which are exposed to the effects of damp or water. The coating material has either a pH-value of at least 11.0 or is provided with a base material for the coating whereby the pH-value is at least 11.0. The coating material is characterised in that it contains a biocide which bonds to solid particles in a carrier material and is released in a delayed manner therefrom.

Abstract: The invention relates to a biocidal composition which can be added to materials which can be attacked by harmful micro-organisms. The composition comprises 2-methylisothiazoline-3-on as biocidal active ingredient and at least one other biocidal active ingredient. The biocidal composition is characterised in that the composition contains formaldehyde or a formaldehyde-depot material, 2-brom-2-nitro-1,3 propandiol, polyhexamethylene biguanide, o-phenylphenol, pyrithione, n-butyl-1,2-benzisothiazoline-3-on, n-hydroxymenthyl-1,2-benzisothiazoline-3-on or benzalkonium chloride as said other biocidal active ingredient.

Abstract: A biocide composition is provided as an addition to substances that can be infected by harmful microorganisms, in which the biocide composition has at least two active biocidal substances, one of which is 2-methylisothiazolin-3-one. The composition is characterized in that it contains 1,2-benzisothiazolin-3-one, compositions containing 5-chloro-2-methylisothiazolin-3-one being excluded. In comparison with its individual components, the composition of the invention has a synergistic biocidal activity.
