Abstract
Methods for inhibiting microbial growth in aqueous systems by the use of synergistic mixtures comprising poly(hexamethylammonium) chloride and at least one compound selected from the group consisting of poly(iminoimidocarbonyliminoimidocarbonyliminohexamethylene hydrochloride ("PHMB"), dodecylguanidine hydrochloride ("DGH") and poly[oxyethylene (dimethylimino) ethylene-(dimethylimino) ethylene dichloride] ("PDED"). Antimicrobial compositions comprising the synergistic mixture and a carrier are also disclosed.
Claims12
A synergistic composition for inhibiting the growth of yeasts, molds or algae, comprising synergistic effective amounts of between 33% and 97% of poly(hexamethylammonium) chloride and between 3% and 67% of poly(iminoimidocarbonyliminoimidocarbonyliminohexamethylene) hydrochloride ("PHMB").
An antimicrobial composition for inhibiting the growth of yeasts, molds or algae comprising synergistic effective amounts of between 33% and 97% of poly(hexamethylammonium) chloride and between 3% and 67% of poly(iminoimidocarbonyliminoimidocarbonyliminohexamethylene) hydrochloride ("PHMB"), and a carrier in liquid form.
A method of inhibiting the growth of microbes selected from the group consisting of yeasts, molds and algae, comprising contacting said microbes with an antimicrobially effective amount of a synergistic composition comprising between 33% and 97% of poly(hexamethylammonium) chloride and between 3% and 67% of poly(iminoimidocarbonyliminoimidocarbonyliminohexamethylene) hydrochloride ("PHMB").
