Abstract

The article describes the investigation results on the antibacterial activity of the Australian-originated tea tree (Alternifolia melaleuca) oil and its application in cosmetics production. The research points out that not only terpinen-4-ol but also other components of the oil have rather high antibacterial activity. With a dose of about 0.25%, all fractions of the tea tree oil could destroy 90% the typical bacteria as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Candida albacans. A test of adding 0.25% of the oil into cosmetics shows that the product retains its antibacterial activity and pleasant odor as well. The investigation results contribute to its application prospect in producing detergents, cosmetics and pharmaceuticals of suitable antibacterial activity.
