In this study, a promising microemulsion delivery system containing andiroba essential oil, lemongrass essential oil and chitosan was developed and applied in 100% cotton fabrics to provide antibacterial functionality. The developed micellar systems were characterized by coloration, electrical conductivity, viscosity, zeta potential, particle size, temperature resistance and microbial activity analyses. The microemulsions in the substrates were verified by Fourier transform infrared spectroscopy (FTIR) and microbial activity analyses before and after domestic washing of the functionalized fabrics. Microemulsions SMs_P1 and SMs_P4 showed more significant inhibitory action against Staphylococcus aureus, Escherichia coli and Enterobacter sp. bacteria, observed in the functionalized samples before and after domestic washing. In this study, microemulsions SMs_P1 and SMs_P4 developed and tested on 100% cotton fabrics have greater application viability because they showed inhibitory action against Gram-positive and Gram-negative bacteria S. aureus, E. coli and Enterobacter sp. The antibacterial functionality of the microemulsions was also observed in 100% cotton fabrics treated with them (TA_SMs_P1 and TA_SMs_P4) before and after domestic washing, as demonstrated by FTIR and antimicrobial activity analyses, with greater emphasis on microemulsion SMs_P4, which has lower concentrations than SMs_P1 and showed significant values (halo size) in blocking the action of E. coli bacteria.

含有安迪罗巴精油和柠檬草精油的 O/W 型胶束系统，用于消除细菌活性

在这项研究中，开发了一种含有安迪罗巴精油、柠檬草精油和壳聚糖的有前景的微乳液输送系统，并将其应用于 100% 棉织物，以提供抗菌功能。所开发的胶束系统通过着色、电导率、粘度、zeta 电位、粒径、耐温性和微生物活性分析进行表征。通过傅里叶变换红外光谱 (FTIR) 和功能化织物家庭洗涤前后的微生物活性分析来验证基材中的微乳液。微乳SMs_P1和SMs_P4对金黄色葡萄球菌、大肠杆菌和肠杆菌有更显着的抑制作用。在家庭洗涤之前和之后在功能化样品中观察到的细菌。在这项研究中，在 100% 棉织物上开发和测试的微乳液 SMs_P1 和 SMs_P4 具有更大的应用可行性，因为它们对革兰氏阳性和革兰氏阴性细菌金黄色葡萄球菌、大肠杆菌和肠杆菌具有抑制作用。正如 FTIR 和抗菌活性分析所证明的那样，在家庭洗涤前后用微乳液处理的 100% 棉织物（TA_SMs_P1 和 TA_SMs_P4）中也观察到了微乳液的抗菌功能，重点是微乳液 SMs_P4，其浓度低于 SMs_P1并在阻断大肠杆菌的作用方面显示出显着的值（光环大小）。
