Abstract

Abstract A method of inhibiting growth of bacteria comprising exposing the bacteria to an effective concentration of a polyunsaturated long-chain alcohol selected from the group consisting of linolenyl alcohol and linoleyl alcohol. The bacteria may be selected from the group consisting of Clostridium butyricum, Clostridium perfringens, Streptococcus mutans, Streptococcus mutans BHT and Streptococcus sanguis. A bactericidal product comprising an orally administerable product. The orally administerable product contains an effective concentration of antibacterial compound selected from the group consisting of linolenyl alcohol and linoleyl alcohol to produce an orally administerable product which will resist growth of bacteria selected from the group consisting of Clostridium butyricum, Clostridium perfringens, Streptococcus mutans, Streptococcus mutans BHT and Streptococcus sanguis.
