Antibacterial and Anti-Acne Activity of Benzoyl Peroxide Nanoparticles Incorporated in Lemongrass Oil Nanoemulgel

The goal of this study was to make Benzoyl Peroxide (BPO) nanoemulgel to improve its ability to kill bacteria. BPO has trouble getting into the skin, being absorbed by the skin, staying stable, and being spread out.A BPO nanoemulgel formulation was prepared by combining BPO nanoemulsion with Carbopol hydrogel. The drug was tested for solubility in various oils and surfactants in order to select the best oil and surfactant for the drug, and then the drug nanoemulsion formulation was prepared using a self-nano-emulsifying technique with Tween 80, Span 80, and lemongrass oil. The drug nanoemulgel was looked at in terms of its particle size, polydispersity index (PDI), rheological behavior, drug release, and antimicrobial activity.Based on the solubility test results, lemongrass oil was the best solubilizing oil for drugs, while Tween 80 and Span 80 demonstrated the highest solubilizing ability for drugs among the surfactants. The optimum self-nano-emulsifying formulation had particle sizes of less than 200 nm and a PDI of close to zero. The results showed that incorporating the SNEDDS formulation of the drug with Carbopol at various concentrations did not cause a significant change in the particle size and PDI of the drug. The zeta potential results for drug nanoemulgel were negative, with more than 30 mV. All nanoemulgel formulations exhibited pseudo-plastic behavior, with 0.4% Carbopol exhibiting the highest release pattern. The drug nanoemulgel formulation worked better against bacteria and acne than the product on the market.Nanoemulgel is a promising way to deliver BPO because it makes the drug more stable and increases its ability to kill bacteria.
