摘要

Functional textiles capable of releasing bioactive compounds onto the skin are increasingly being investigated for applications in health and beauty care. Solid lipid nanoparticles (SLNs) offer a promising approach for encapsulating and stabilizing sensitive compounds such as vitamins. In this study, SLNs containing olive oil, vitamin E, and vitamin C (in a 6:3:1 w/w ratio) were prepared via high-speed homogenization using Emulgade (2%) as the solid lipid matrix and Tween 80 (1%) as the surfactant. The encapsulated system was applied to cotton and viscose fabrics through impregnation or soaking methods. Fabric properties, antioxidant activity via ABTS radical scavenging, and release kinetics were evaluated. Results showed that impregnation fabrics exhibited higher overall antioxidant activity compared to soaking fabrics (81.83±0.38% vs. 42.58±0.52%). A rapid release of active compounds occurred within the first 10 min (16.84%), followed by a slower release phase. Notably, cotton fabrics exhibited superior retention and release efficiency compared to viscose, attributed to their inherently porous, highly absorbent structure. These findings support the potential for developing advanced functional textiles that enable the controlled delivery of cosmetic and pharmaceutical agents in dermatological and healthcare applications.
