Melaleuca alternifolia (Maiden & Betche) Cheel (family Myrtaceae) is harvested from natural stands and plantations for production of tea-tree oil. The therapeutic properties of essential oil of tea tree (AAT) are antimicrobial, antiseptic and antiviral.1,2 The AAT is colorless to pale yellow liquid and it is extracted from the leaves and twigs by steam distillation. Essential oils are mixtures of volatile organic compounds, mostly terpenes. The major component of AAT is monoterpene alcohol, terpinene-4-ol (30%). The aim of the study was to evaluate the antimicrobial activity of a new preservative agent for contact lenses obtained with AAT. Studies included evaluation of the effectiveness of a new preservative solution designed on planktonic and biofilms cultures of Staphylococcus aureus ATCC 29213 and Pseudomonas aeruginosa ATCC 27856.
