en.wikipedia.org/wiki/Disinfectant CachedDisinfectants are chemical agents designed to inactivate or destroy microorganisms on inert surfaces. Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than sterilization, which is an extreme physical or chemical process that kills all types of life.
•A chemical agent that destroys most pathogens but may not kill bacterial spores. •Should only be used if heat treatment is impractical •The broad category of disinfection may be subdivid- ed into high-level, intermediate-level, and low-level disinfection according to the anti-microbial activity of the disinfectant.

disinfectants-and... CachedAcidic and Alkaline Compounds: The efficacy of acidic and alkaline agents is linked to the concentration of hydrogen (H) and hydroxyl (OH) ions. H ions destroy the amino-acid bond in nucleic acids, modify the cytoplasmic pH and precipitate proteins and OH ions saponify the lipids in the enveloping membrane, leading to the destruction of the superficial structure. Chlorine and derivatives: Chlorine and derivatives kill pathogens such as bacteria and viruses by breaking the chemical bonds in their molecules. Disinfectants that are used for this purpose consist of chlorine compounds that can exchange atoms with other compounds, such as enzymes in bacteria and other cells. Quaternary Ammonium compounds: Quaternary ammonium compounds (QACs) have strong bactericidal properties, but weak detergent properties. Their antimicrobial properties depend on their structure and size, but especially on the length of the long-chain alkyl group. Phenolic compounds: Phenol and its derivatives exhibit several types of bactericidal action. Mechanism of action: Cross-linking, coagulating, and clumping. See all full list on pharmawareness.com
The past decades there have been legions of literature on the modes of action (MOA) of, and resistance to, disinfectants, and there has been rising scientific debate on the contribution of disinfectants to the increased frequency of antibiotic resistant microorganisms (White and McDermott, 2001, Maillard, 2002, Davies and Davies, 2010, Russell, 2003b, McDonnell and Russell, 1999, Bridier et al., 2011).

Phenolic disinfectants are effective against bacteria (especially gram positive bacteria) and
Disinfectants can act on microorganisms in two different ways: growth inhibition (bacteriostasis, fungistasis) or lethal action (bactericidal, fungicidal or virucidal effects). Only the lethal effects are of interest in disinfection and, as the objects of treatment have no inherent means of defence, lethality is the desired objective.
This review considers what is known about the mode of action and spectrum of activity of antiseptics and disinfectants. The widespread use of these products has prompted some speculation on the development of microbial resistance, in particular whether antibiotic resistance is induced by antiseptics or disinfectants.
