Wonderful catch! This was an unfortunate error on my part. The initial claim was based on this source: https://www.listerineprofessional.com/products/oral-care-routine/ada-seal-of-acceptance#:~:text=LISTERINE%C2%AE%20ANTISEPTIC%20IS%20THE,AND%20REDUCE%20PLAQUE%20AND%20GINGIVITIS https://www.listerineprofessional.com/products/oral-care-rou... Thank you so much for bringing this to my attention. I have amended the article, and have included a footnote reflecting the initial error. Fortunately, I don't think that this altars the approach to the valuation portion of the analysis.
