AbstractAcne is a skin condition arising from excess sebum production and microbial overgrowth within the pilosebaceous unit. Several commercial essential oils have shown promising activity against acne-related pathogens. Due to their volatility and thermal instability, the formulation of essential oils into commercial products remains a pharmaceutical challenge. Thus, this study aimed to develop a viable anti-acne topical treatment as an oil-in-water emulsified lotion to overcome these challenges. Chrysopogon zizanioides (vetiver) displayed noteworthy antimicrobial activity with a mean minimum inhibitory concentration of 0.14 mg/mL against Cutibacterium acnes, Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus pyogenes. Emulsified lotions containing C. zizanioides were developed through the hydrophilic-lipophilic balance approach. At tested hydrophilic-lipophilic balance values of 8, 9, and 10, C. zizanioides emulsified lotions displayed maximum stability at hydrophilic-lipophilic balance 9 with a minimum change in mean droplet size and polydispersity index of 20.61 and 33.33%, respectively, over 84 days. The C. zizanioides emulsified lotion at optimum hydrophilic-lipophilic balance 9 completely inhibited the growth of C. acnes and killed S. aureus, S. epidermidis, and S. pyogenes within 24 h. Additionally, the lotion retained antimicrobial activity against these test micro-organisms over the 84-day stability test period. Thus, the C. zizanioides emulsified lotion demonstrated physical stability and antimicrobial efficiency, making it an ideal natural product anti-acne treatment.

RESUMO No presente estudo avaliou-se a remoção de demanda bioquímica de oxigênio (DBO), nitrogênio total (NT) e fósforo total (PT) da água residuária de suinocultura (ARS) em sistemas alagados construídos (SACs) de escoamento horizontal subsuperficial, além da contribuição das espécies vegetais cultivadas: Polygonum punctatum (erva-de-bicho) e Chrysopogon zizanioides (capim-vetiver). Foram implantados três SACs, utilizando-se argila expandida como meio suporte, sendo um cultivado com P. punctatum (SACE), outro cultivado com C. zizanioides (SACV) e um mantido como controle, sem cultivo (SACC). Para um tempo de retenção hidráulica nominal (τ) de 3,2 dias, observou-se remoção de DBO, NT e PT, ao longo do período experimental, com eficiências médias de 85, 38 e 51% (SACC), 89, 48 e 69% (SACE) e 81, 36 e 45% (SACV), respectivamente. O melhor desempenho foi observado no SACE. Foram obtidas, em termos de matéria seca, produtividades de 2,79 e 1,91 g m-2 d-1 e remoções de NT de 1,54 e 1,01% e de PT de 0,81 e 1,19%, da carga aplicada, para a erva-de-bicho e o capim-vetiver, respectivamente.
