The o-cymen-5-ol (C10H14O) is a substituted phenolic compound derivative of isopropyl cresol. It was first synthesized in 1954 as an isomer of thymol, and it is colourless, odourless, and has a high stability and a favourable safety profile. To date, several studies have shown that its use combined with zinc chloride prevents the proliferation of pathogenic bacteria and, therefore, the appearance of the aforementioned oral pathologies, halitosis, gingival bleeding, plaque formation and dental erosion[1].
