Abstract

Tea tree oil (TTO), the essential oil of Melaleuca alternifolia L., is one of the most popular agents used in cosmetics. This study aimed to explore the correlations of components in TTO with its anti-acne activities and skin irritation. TTOs were isolated from the leaves (TTO-L), twigs, and branches of M. alternifolia by steam distillation, and the components analyzed by gas chromatography–mass spectrometry. Results showed that components of TTO-L satisfied the International Organization for Standardization (ISO) 4730 guidelines. TTO-L and its components, terpinen-4-ol, terpinolene, α-terpinene, and α-terpineol, had strong inhibitory activities against Propionibacterium acnes and Staphylococcus aureus . Moreover, six TTO formulas (DF-TTO) were designed according to ISO 4730 guidelines by adjusting the proportions of these four active components. All DF-TTO formulas showed a positive correlation between terpinen-4-ol concentration and anti- P. acnes activity. In the skin irritation assay, TTO-L, terpinen-4-ol, and 1,8-cineole did not cause significant skin irritation at 2% per site. In conclusion, terpinen-4-ol is the major active component responsible for TTO's antibacterial efficacy, while minor components in TTO also contributed to its efficacy. Moreover, we suggest that a concentration less than 5% is more suitable and safer for treating acne than higher concentrations.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
