A proposed “biocidal complex” aimed at killing bacteria
and destroying at least part of the biofilm contains: a freeradical
generating compound (e.g. hydrogen peroxide), a
GRAS disinfectant (e.g. thymol) and an acid sulphate (e.g.
sodium bisulphate) to catalyse the free radical formation
. The compounds should be maintained separately until
use. This formulation may be used to clean and disinfect
water lines in dental equipment. Mixtures of furanones and
other disinfectants, such as at least one organosilane with
quaternary ammonium functionality and/or at least one
quaternary ammonium compound can make a synergistic
antimicrobial composition effective against bacteria, yeasts
and fungi .
