For corrosives it really is all about concentration. It is not a poison or a carcinogen. If it is not burning it is not harming. I agree putting it in my eye or eating it is not a good idea.

yes it does smell similar to the quat salt preparations they use to clean down grocery store meat departments. These chemicals have regulated usage and concentrations for these purposes. Physan20 does not. I just think its bad advice to advocate its use as a household cleaner/disinfectant because it's not intended for that. Regular dish soap rapidly inactivates coronavirus...

Health effects
Quaternary ammonium compounds can display a range of health effects, amongst which are mild skin and respiratory irritation [24] up to severe caustic burns on skin and the gastrointestinal wall (depending on concentration), gastrointestinal symptoms (e.g., nausea and vomiting), coma, convulsions, hypotension and death.[25]
They are thought to be the chemical group responsible for anaphylactic reactions that occur with use of neuromuscular blocking drugs during general anaesthesia in surgery.[26] Quaternium-15 is the single most often found cause of allergic contact dermatitis of the hands (16.5% in 959 cases)[27]
Possible reproductive effects in laboratory animals
Quaternary ammonium-based disinfectants (Virex and Quatricide) were tentatively identified as the most probable cause of jumps in birth defects and fertility problems in caged lab mice. The quat ingredients in the disinfectants include alkyl dimethyl benzyl ammonium chloride (ADBAC) and didecyl dimethyl ammonium chloride (DDAC).[28][29] A similar link was tentatively identified in nurses.[30] The studies contradict earlier toxicology data reviewed by the U.S. Environmental Protection Agency (U.S. EPA) and the EU Commission.[31]

Over-usage of quat salts in the home allows these chemicals to build up in the dusts of your home. I personally would avoid that, especially if you have autoimmune issues, skin sensitivities, asthma or anything that makes you susceptible to irritants. The avg age is pretty high on this forum so I imagine most don't care about the potential reproductive harm... but some of us do. Especially for corona virus why not wipe down surfaces with detergent and 10% bleach? its much less persistent and poses less threat to the quality of a home environment.
