ABSTRACT

Considering the quantity of pathogenic organisms and bacteria found in the air, soil, skin, and various locations within homes, the existence of antibacterial soaps is a significant part of keeping humankind healthy and safe. In recent years, there has been a growing focus on essential oils in the cosmetic, pharmaceutical, and housekeeping fields. Essential oils contain differing types of phenolics, terpenes, aldehydes, and other antimicrobial compounds which could indicate antimicrobial activity. The reactivity of those oils depends upon the nature and composition of their functional groups. Despite the growing interest in these oils and hypothesized health benefits, there is hardly any concrete scientific evidence that essential oils work as advertised. Therefore, the present experiment provides an in depth summary of the effect essential oils have on bacteria when directly compared to more commonly known products. Focusing on dōTERRA On Guard®, the various effects on common household bacteria are outlined, compared directly to Dawn Ultra Dish Soap® and Member’s Mark Hand Soap®. Finally, analytical methods were used to assess the antibacterial properties of the four soaps with respect to their differing physical properties. The aim of this paper is to explore the antibacterial potential of dōTERRA On Guard® on human pathogens, in comparison to Dawn Ultra Dish Soap® and Member’s Mark Hand Soap®. Direct comparison will allow a quality assessment that will be informative to consumers of these products.
