摘要:

用溶胶-凝胶法制备壳聚糖纳米颗粒,以PDMS为油相,高速剪切得壳聚糖皮克林乳液(CS-PE),其中壳聚糖颗粒占乳液总质量0.4%,水油比4∶4。再经高速剪切制得负载馨肤白377 (PR)的CS-PE (称其PR CS-PE),其包封率为97.2%±0.2%,载药量为2.3%±0.01%。PR CS-PE的DPPH和ABTS自由基清除率分别为77.4%和93.8%,表明其具有良好的抗氧化性。Franz体外透皮实验结果表明PR CS-PE中PR为缓慢释放。此外PR CS-PE可有效抑制斑马鱼黑色素的生成,具有良好的美白活性。斑马鱼胚胎发育和细胞毒性实验结果表明负载有馨肤白的壳聚糖皮克林乳液配方与纯PR相比,毒性降低,表明馨肤白/壳聚糖皮克林乳液在化妆品领域具有潜在的应用价值。

Abstract:

Chitosan nanoparticles ((212.2±3.2) nm) were synthesized via sol-gel method by adjusting the pH of the chitosan solution. Using polydimethylsiloxane (PDMS) as the oil phase, a chitosan-based Pickering emulsion (CS-PE) was prepared by high-speed shear homogenization, with solid particle mass fraction of 0.4% and water-to-oil volume ratio of 4∶4. Phenylethyl resorcinol (PR) was subsequently loaded into the emulsion to form the PR-loaded CS-PE (PR CS-PE). The encapsulation efficiency and drug loading of PR in PR CS-PE were determined to be 97.2%±0.2% and 2.3%±0.01%, respectively. The radical scavenging rates of PR CS-PE for 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and 2, 2-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) were measured to be 77.4% and 93.8%, respectively, indicative of significant antioxidant activity. The results of Franz diffusion cell test indicated that the PR within the emulsion exhibited sustained release behavior. Furthermore, PR CS-PE could effectively inhibit the melanogenesis in zebrafish models, suggesting notable skin-whitening efficacy. Results of the zebrafish embryonic development and cytotoxicity assay indicated that the PR-loaded chitosan-based Pickering emulsion exhibited lower toxicity compared with free PR. These findings suggest the potential application of the PR/chitosan Pickering emulsion in cosmetics.
