With all the advice about how to clean and keep ourselves healthy, I became curious about the difference between antibacterial, antiseptic, and disinfectant.

First all three contain chemicals aimed at killing or stopping the growth of bacteria, viruses, and/or fungi.

An antibacterial battles bacterial and fungal infections and “are useful where the level of sanitation is critical and additional precautions need to be taken to prevent spread of disease”, not necessarily for regular day-to-day use (Science). They won’t work against viruses.

An antiseptic, a.k.a. skin disinfectant, is an antimicrobial and a chemical that is applied to your skin to kill or prevent the growth of viruses, bacteria, and fungi.

A disinfectant is an antimicrobial used on inanimate objects and surfaces, killing or preventing the growth of viruses, bacteria, and fungi. Do NOT use in or on your body!

Word Confusions . . .

. . . started as my way of dealing with a professional frustration with properly spelled words that were out of context in manuscripts I was editing as well as books I was reviewing. It evolved into a sharing of information with y’all. I’m hoping you’ll share with us words that have been a bête noire for you from either end.
