SYNERGISTIC BIOCIDAL COMPOSITIONS COMPRISING A THP SALT

摘要

A SYNERGISTIC COMPOSITION COMPRISING A THP SALT AND A BIOPENETRANT, IN WHICH THE BIOPENETRANT COMPRISES A POLYMER OF AN UNSATURATED CARBOXYLIC ACID OR A COPOLYMER OF AN UNSATURATED CARBOXYLIC ACID WITH A SUIPHONIC ACID, SAID POLYMER OR COPOLYMER BEING TERMINATED BY A MONO- OR DI-PHOSPHONATED UNSATURATED CARBOXYLIC ACID GROUP OR HAVING SUCH MONOMERS INCORPORATED INTO THE POLYMER BACKBONE. THIS COMPOSITION ACTS SYNERGISTICALLY TO ENHANCE THE BIOCIDAL EFFICACY OF THE THP SALT AGAINST BOTH PLANKTONIC (FREE-SWIMMING) AND SESSILE (ATTACHED) BACTERIA, AND ALSO ACTS SYNERGISTICALLY TO ENHANCE THE EFFICACY OF THE THP SALT IN THE DISSOLUTION OF IRON SULPHIDE SCALE.
