Abstract: THE PRESENT INVENTION RELATES TO CERTAIN PROCESSES AND COMPOSITIONS USEFUL FOR INHIBITING AND/OR CONTROLLING THE GROWTH OF SLIME IN WATER AND, IN PARTICULAR, WATER EMPLOYED FOR INDUSTRIAL PURPOSES. WATER EMPLOYED IN THE MANUFACTURE OF PULP PAPER AND WATER EMPLOYED IN COOLING WATER SYSTEMS, AS WELL AS OTHER INDUSTRIAL WATERS, PROVIDE ENVIRONMENTS WHICH ARE CONDUCTIVE TO SLIM FORMATION. THE NOVEL COMPOSITION OF THE PRESENT INVENTION ARE MIXTURES WHICH SHOW UNEXPECTED SYNERGISTIC ACTIVITY AGAINST MICROORAGANISMS, INCLUDING BACTERIA, FUNGI AND ALGAE, WHICH PRODUCE SLIME IN AQUEOUS SYSTEMS. THE SLIME, OF COURSE, IS OBJECTIONABLE FROM AN OPERATIONAL AND /OR AN AESTHETIC POINT OF VIEW. SPECIFICALLY, THE INVENTION IS DIRECTED TO AND THE USE OF COMPOSITIONS COMPRISING A COMBINATION OF 5-CHLORO-4-PHENYL - 12, - DITHIOLE-3-/NE AND PHENOLIC COMPOUNDS (OR MIXTURES THEREOF). THE INVENTIVE COMPOSITIONS INHIBIT THE GROWTH OF SLIME IN WATER, OR MORE SPECIFICALLY, POSSESS BIOCIDAL ACTIVITY AGAINST BACTERIA, FUNGI AND/OR ALGAE. THE PHENOLIC COMPOUNDS CONTMPLATE FOR USE IN ACCORDANCE WITH THE PRESENT INVENTION ARE THOSE PHENOLIC COMPOUNDS WHICH POSSESS THE CAPACITY TO KILL OR INHIBIT THE GROWTH OF SLIME-FORMING MICROORGANISMS SUCH AS BACTERIA, FUNGI AND ALGAE. THE TYPE PHENOLIC COMPOUNDS ENCOMPASSED BY THE PRESENT INVENTION MAY KBE EXAMPLIFIED BY: PHENOL, ORTHO-PHENYLPHENOL, 2,3,4,6TETRACHLOROPHENOL, 4-CHLORO - 2 - CYCLOPENTYLPHENOL AND 2-CHLORO-4-PHENYLPHENOL.

Abstract: THE PRESENT INVENTION RELATES TO CERTAIN PROCESS AND COMPOSITIONS USEFUL FOR INHIBITING AND/OR CONTROLLING THE GROWTH OF SLIME IN WATER AND, IN PARTICULAR, WATER EMPOLYED FOR INDUSTRIAL PURPOSES. WATER EMPLOYED IN THE MANUFATURE OF PULP PAPER AND WATER EMPLOYED IN COOLING WATER SYSTEMS, AS WELL AS OTHER INDUSTRIAL WATERS, PROVIDE ENVIRONMENTS WHICH ARE CONDUCTIVE TO SLIME FORMATION. THE NOVEL COMPOSITIONS OF THE PRESENT INVENTION ARE MIXTURES WHICH SHOW UNEXPECTED SYNERGISTIC ACTIVITY AGAINST MICROORGANISMS, INCLUDING BACTERIA, FUNGI AND ALGAE WHICH PRODUCE SLIME IN AQUEOUS SSYSTEM. THE SLIME OF COURSE, IS OBJECTIONABLE FROM AN OPERATIONAL AND/OR AN AESTHETIC POINT OF VIEW. SPECIFICALLY, THE INVENTION IS DIRECTED TO AND THE USE OF COMPOSITIONS COMPRISING A COMBINATUION OF 5-CHLORO-4-PHENYL-1,2-DITHIOEL-3-ONE OR DERIVAIVES THEREOF AND SORBITAN MONO OLEATE OR DERIVATIVES THEREOF. THE INVENTIVE COMPOSITIONS INHIBIT THE GROWTH OF SLIME IN WATER, OR MORE SPECIFICALLY, POSSESS BIOCIDAL AFIVITY AGAINST BACTERIA, FUNGI AND/OR ALGAE. THE DERIVATIVES CONTEMPLATED FOR USE IN ACCORDANCE WITH THE PRESENT INVENTION ARE THOSE WHICH POSSESS THE CAPACITY TO KILL OR INHIBIT THE GROWTH OF SLIME-FORMING MICROORGANISMS SUCH AS BACTERIA, FUNGI AND ALGAE.
