  • Stabilized haloalkynyl microbicide compositions
    Patent number: 7083801
    Abstract: Antimicrobial compositions based on haloalkynyl active ingredients that are chemically stable in the presence of chelated metal ion are disclosed. Particularly preferred is the use of metal ion chelating agents based on selected amine compounds that provide the metal ion in a form sufficient to provide stability to other antimicrobial components in the aqueous composition, but without concurrently degrading the antimicrobial effectiveness of the haloalkynyl active ingredient.
