Objectives: We studied the chemical compositions of their extracts and their applicability as cosmetic ingredients. Methods/Statistical Analysis: The current work was designed to set up analytical methods in order to analysis the components and the antimicrobial and anti-oxidative effects of commercially available essential oils obtained from different companies. These investigations were the study of antimicrobial activities of four Lavender oils and four Eucalyptus oils against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albican. The chemical composition of their oils obtained from four different samples was evaluated using the GC-MS. Findings: Lavender essential oils (Lavandula angustifolia) had much more intensive antimicrobial effects against Escherichia coli and Pseudomonas aeruginosa. Both the lavender and eucalyptus oils had a high antimicrobial effect against Candida albicans. Also, four essential oils from each of lavender and eucalyptus had anti-oxidative effects. The scientifically based properties of Lavender oils include their antioxidative and antimicrobial attributes. It was revealed that linalool and linalyl acetate which are the chemical components of lavender oils are more excellent than the1,8-cineole component of lavender oils in terms of anti-oxidative and antimicrobial activities. It was also identified that other minor chemical components of essential oils make a contribution to synergic effects. These results suggest that the content of each of major components of lavender and eucalyptus essential oils is different. As the four kinds of each of lavender and eucalyptus are all different in the content of major components and in the effect of their anti-oxidative and antimicrobial activities, it is essential to analyze these components and evaluate the content of each major component. Improvements/Applications: The antimicrobial and anti-oxidative activity of lavender and eucalyptus oils prevents cosmetic products from being contaminated, cures skin infection, and soothes the broken or inflamed skin.
