The purpose of this study was to develop tea tree oil (TTO)-loaded chitosan-poly(?-caprolactone) core-shell nanocapsules (NC-TTO-Ch) aiming the topical acne treatment. TTO was analyzed by gas chromatographymass spectrometry, and nanocapsules were characterized regarding mean particle size (Z-average), polydispersity index (PdI), zeta potential (ZP), pH, entrapment efficiency (EE), morphology by Atomic Force Microscopy (AFM), and anti-Cutibacterium acnes activity. The main constituents of TTO were terpinen-4-ol (37.11 %), ?-terpinene (16.32 %), ?-terpinene (8.19 %), ?-cimene (6.56 %), and ?-terpineol (6.07 %). NC-TTO-Ch presented Z-average of 268.0 ± 3.8 nm and monodisperse size distribution (PdI < 0.3). After coating the nanocapsules with chitosan, we observed an inversion in ZP to a positive value (+31.0 ± 1.8 mV). This finding may indicate the presence of chitosan on the nanocapsules? surface, which was corroborated by the AFM images. In addition, NC-TTO-Ch showed a slightly acidic pH (~5.0), compatible with topical application. The EE, based on Terpinen-4-ol concentration, was approximately 95 %. This data suggests the nanocapsules? ability to reduce the TTO volatilization. Furthermore, NC-TTO-Ch showed significant anti-C. acnes activity, with a 4× reduction in the minimum inhibitory concentration, compared to TTO and a decrease in C. acnes cell viability, with an increase in the percentage of dead cells (17 %) compared to growth control (6.6 %) and TTO (9.7 %). Therefore, chitosan-poly(?-caprolactone) core-shell nanocapsules are a promising tool for TTO delivery, aiming at the activity against C. acnes for the topical acne treatment.
