Melaleuca Alternifolia (Tea Tree) Leaf Oil

Tea Tree Oil is a pale yellow to colorless essential oil steam-distilled from the leaves of Melaleuca alternifolia, a tree native to Australia. It contains high concentrations of terpinen-4-ol (typically 30-48%), which gives it potent antimicrobial properties against bacteria, fungi, and some viruses, making it a popular natural alternative in acne treatments and scalp care products. Formulators value it for its dual action as both a functional antimicrobial agent and a characteristic fresh, medicinal fragrance, though its volatility and potential for oxidation require careful formulation and packaging considerations.
