    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

    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.
