Abstract:
Conventional wet facial masks face critical environmental and functional limitations, including reliance on non-biodegradable polymers, preservative-dependent formulations, and inefficient transdermal delivery of bioactive macromolecules. This study developed eco-friendly nanofibrous facial membranes by integrating natural deep eutectic solvents (NADES) with electrospinning to enhance Platostoma palustre polysaccharide (PPP) delivery. The L-proline/lactic acid NADES (L-proLA) increased PPP solubility 51.63-fold through hydrogen-bond disruption, confirmed by FT-IR analysis and Kamlet-Taft parameters (α = 2.904). Electrospinning with polyvinyl alcohol (PVA) created 40-150 nm diameter nanofibers (DPNMs) enabling dual transdermal mechanisms: lactic acid's stratum corneum disruption and sustained nanofiber release. DPNM-12 achieved 10.11 ± 0.13 mg/cm2 cumulative skin permeation in 24 h. The membranes demonstrated 95.36 ± 0.17 % Staphylococcus aureus and 93.59 ± 0.15 % Escherichia coli inhibition, suppressed macrophage nitric oxide by 75.8 %, and maintained >90 % fibroblast viability. Utilizing food-grade biodegradable components (PVA, NADES) eliminated organic solvents, establishing a green platform for polysaccharide-based skincare. This technology addresses conventional masks limitations by combining antimicrobial/anti-inflammatory functions with scalable eco-friendly production.
