Abstract
Ortho phenylphenol or its sodium salt is shown to form synergistic antimicrobial mixtures with nitrogen and aldehyde-containing microbiocides.
Claims8
An antimicrobial synergistic mixture of orthophenylphenol or its sodium salt and dodecylguanidine hydrochloride wherein the mixture is determined to be antimicrobial synergistic by having a synergy index of less than 1 in a synthetic white water at pH from about 7-9.
An antimicrobial synergistic mixture of orthophenylphenol or its sodium salt and dodecylguanidine hydrochloride at a pH of about 7.0 in a ratio of dodecyl guanidine hydrochloride to orthophenylphenol or its sodium salt of about 4:1.
An antimicrobial synergistic mixture of orthophenylphenol or its sodium salt and dodecylguanidine hydrochloride at a pH from about 8.0-9.0 in a ratio of dodecylguanidine hydrochloride to orthophenylphenol or its sodium salt of about 16:1-65:1.
An antimicrobial synergistic mixture of orthophenylphenol or its sodium salt and dodecyl guanidinehydrochloride in a coating, wherein the mixture is determined to be antimicrobial synergistic by the coating containing the antimicrobial mixture having superior antimicrobial effectiveness when compared with the coating containing orthophenylphenol or its sodium salt without dodecylguanidine hydrochloride and the coating containing dodecylguanidine hydrochloride without orthophenylphenol or its sodium salt.
