Melaleuca Leucadendron (Cajuput) Oil

What is Melaleuca Leucadendron (Cajuput) Oil?

Melaleuca Leucadendron, known as the cajuput tree, is an evergreen species native to Southeast Asia's tropical regions, such as Indonesia and Malaysia. The oil is extracted via steam distillation from its fresh leaves and terminal branches, yielding a clear to pale yellow liquid with a pungent, cineole-dominant scent. Key constituents include 1,8-cineole (40-65%), alpha-terpineol, limonene, and pinene isomers, giving it aromatic and mildly astringent properties. In cosmetic formulations, it serves as a fragrance component and functional additive, typically in toners, cleansers, and lotions. Its volatile molecules neutralize and override off-notes for improved scent profiles, while natural solvents and humectant-like effects deliver a tightening, invigorating after-feel that preps skin.
