Abstract

There is provided a natural antimicrobial including a mixture of tree essential oils, soybean oil, and a residual hydrocarbon extract extracted from a rutaceae plant, wherein the mixture is supported in a supporter, and an article including the antimicrobial are provided. The antimicrobial is comprised of only natural materials, so it is harmless to human beings and environmentally friendly. Also, in the antimicrobial, tree essential oils is supported together with soybean carrier oil in a supporter, and thus, volatility of tree essential oils is controlled by the soybean oil, whereby the tree essential oils is naturally emitted to have an effective antibiosis for a long period of time. Thus, extra power, driving device (e.g., a fan), or the like, is not required to emit the tree essential oils. In addition, the antimicrobial is actively emitted in the air, having efficacy of continuously annihilate bacteria, virus, or the like.
