Novel mechanisms of alkyldimethylbenzalkonium chloride in virucidal activity.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The cationic surfactant, alkyldimethylbenzalkonium chloride (BAC), effectively inactivates enveloped viruses, but the underlying mechanism of action is poorly understood. Therefore, this study attempted to elucidate the inactivation mechanism of BAC using actual viruses and characterize the state of BAC in water under the same conditions. Here, we show that at concentrations below the critical micelle concentration (CMC), partial membrane disruption by BAC monomers contributes to the inactivation mechanism. At concentrations above the CMC, solubilization of the envelope component also contributes to virucidal activity. Concentration-related differences in the inactivation mechanism were further evaluated based on the kinetic equation of the reaction, which showed that physicochemical studies are directly related to biochemistry. As enveloped viruses can be viewed as vesicles based on their structure, the results of this study should enhance investigations of non-virus biological vesicles, such as exosomes and drug delivery systems.
