Types of antimicrobial soaps include products that contain triclosan, chlorhexidine, iodine and iodophors
Traditionally, the concentric circle method was required if aqueous iodophors
were used after the alcohol step to prevent reintroduction of contaminants to previously cleansed areas.
provide broad-spectrum coverage, are not associated with microbial resistance, and provide a bacteriostatic effect as long as they remain on the skin.
Examples include alcohol, iodophors
, chlorhexidinegluconate, and quaternary ammonium products.
In fact the iodine status of the UK improved due to the use of iodophors
[added iodine] in the milk industry and the practice of feeding cattle cake to cows in winter.
Traditional aqueous-based iodophors
, such as povidone-iodine, are one of the few products that can be safely used on mucous membrane surfaces.
, hypochlorite, quaternary ammonium compounds are common sanitizers used for cleaning of many dairy utensils and equipment.
There are four standard types or classifications: chlorine-based products, phenolic solutions (water- or alcohol-based), iodophors
and quaternary compounds.
Simple interventions such as use of maximal barrier precautions  and use of chlorhexidine rather than iodophors
for cutaneous antisepsis  have resulted in decreased incidence of CLABSI in randomized trials .
While a number of disinfectants such as alcohols, hypochlorites, chlorohexidine, iodophors
, hydrogen peroxide, and phenolics are used in healthcare facilities, many LTC facilities choose quaternary ammonium compounds (quats) to destroy, inhibit, or prevent growth of microbes on surfaces in patient/resident rooms.
Iodine and iodophors
are effective against Gram-positive, Gram-negative and certain spore-forming bacteria, mycobacteria, viruses and fungi (3,6).
Sodium hydroxide (1% with detergent), oxidizing agents, and iodophors
work well against SVD virus.
