Abstract
Antimicrobial compositions comprising at least two antimicrobial agents exhibit reduced MIC values relative to the MIC for the agents making up the combination when measured alone. The compositions are useful as therapeutic agents such as in oral hygiene products.
Claims24
An oral hygiene product comprising:
- antimicrobial agent A and antimicrobial agent B in an amount effective to inhibit the growth of oral pathogenic bacteria selected from the group consisting of Actinomyces viscosus, Fusobacterium nucleatum, Porphyromonas gingivalis, Streptococcus mutans, and Streptococcus sanguis wherein agents A and B are selected from the group consisting of berberine, cedarwood oil, chloramphenicol, citral, citronella oil, Glycyrrhiza glabra extract, juicy fruit basil oil, juniper berries oil, lemon basil oil, lemon oil, and Rosmarinus officinalis oil, wherein a minimum inhibitory concentration of agent A relative to at least one of the bacteria, in the presence of agent B, is synergistically less than the minimum inhibitory concentration of agent A alone.
An oral hygiene product comprising:
- an antimicrobial agent A comprising geraniol;
- and
- an antimicrobial agent B selected from the group consisting of berberine, cedarwood oil, chloramphenicol, citronella oil, cocamidopropyl dimethylglycine, Glycyrrhiza glabra extract, juicy fruit basil oil, juniper berries oil, lemon basil oil, lemon oil, and Rosmarinus officinalis oil, antimicrobial agent A and antimicrobial agent B being present in an amount effective to inhibit the growth of oral pathogenic bacteria selected from the group consisting of Actinomyces viscosus, Fusobacterium nucleatum, Poryhyromonas gingivalis, Streptococcus mutans, and Streptococcus sanguis, wherein a minimum inhibitory concentration of agent A relative to at least one of the bacteria, in the presence of agent B, is synergistically less than the minimum inhibitory concentration of agent A alone.
An oral hygiene product comprising:
- an antimicrobial agent A comprising cocamidopropyl dimethylglycine;
- and
- an antimicrobial agent B selected from the group consisting of berberine, cedarwood oil, chloramphenicol, citral, citronella oil, Glycyrrhiza glabra extract, juicy fruit basil oil, juniper berries oil, lemon basil oil, lemon oil, and Rosmarinus officinalis oil, antimicrobial agent A and antimicrobial agent B being present in an amount effective to inhibit the growth of oral pathogenic bacteria selected from the group consisting of Actinomyces viscosus, Fusobacterium nucleatum, Porphyromonas gingivalis, Streptococcus mutans, and Streptococcus sanguis, wherein a minimum inhibitory concentration of agent A relative to at least one of the bacteria, in the presence of agent B, is synergistically less than the minimum inhibitory concentration of agent A alone.
A method for inhibiting the growth of bacteria within an oral cavity comprising the step:
- contacting the oral cavity with a composition that includes antimicrobial agent A and antimicrobial agent B in an amount effective to inhibit the growth of oral pathogenic bacteria selected from the group consisting of Actinomyces viscosus, Fusobacterium nucleatum, Porphyromonas gingivalis, Streptococcus mutans, and Streptococcus sanguis, agents A and B selected from the group consisting of berberine, cedarwood oil, chloramphenicol, citral, citronella oil, Glycyrrhiza glabra extract, juicy fruit basil oil, juniper berries oil, lemon basil oil, lemon oil, and Rosmarinus officinalis oil, wherein the minimum inhibitory concentration of agent A relative to at least one of the bacteria, in the presence of agent B, is synergistically less than the minimum inhibitory concentration of agent A alone.
A method of reducing the minimum inhibitory concentration relative to oral pathogenic bacteria selected the group consisting of Actinomyces viscosus, Fusobacterium nucleatum, Poryhyromonas gingivalis, Streptococcus mutans, and Streptococcus sanguis, of an antimicrobial agent A selected from the group consisting of berberine, cedarwood oil, chloramphenicol, citral, citronella oil, geraniol, Glycyrrhiza glabra extract, juicy fruit basil oil, juniper berries oil, lemon basil oil, lemon oil, and Rosmarinus officinalis oil, comprising:
- combining agent A with an antimicrobial agent B different from agent A, agent B being present in an amount effective to provide a synergistic reduction in the minimum inhibitory concentration of agent A relative to at least one of the bacteria, agent B selected from the group consisting of berberine, cedarwood oil, chloramphenicol, citral, citronella oil, geraniol, Glycyrrhiza glabra extract, juicy fruit basil oil, juniper berries oil, lemon basil oil, lemon oil, and Rosmarinus officinalis oil.
A method for reducing the minimum inhibitory concentration of an antimicrobial agent A comprising cocamidopropyl dimethylglycine comprising:
- combining agent A with an antimicrobial agent B different than agent A, agent B being present in an amount effective to provide a synergistic reduction in the minimum inhibitory concentration of agent A relative to at least one of the bacteria, agent B selected from the group consisting of berberine, cedarwood oil, chloramphenicol, citral, citronella oil, geraniol, Glycyrrhiza glabra extract, juicy fruit basil oil, juniper berries oil, lemon basil oil, lemon oil, and Rosmarinus officinalis oil.
