本實驗使用兩階段之超音波震盪法開發W/O/W型雙乳劑固態脂質奈米粒同時包覆疏水性藥物維生素A棕櫚酸酯(RP)與親水性藥物菸鹼醯胺(Vit B3),而此方法具有無須添加有機溶媒即能得到小粒徑且穩定之固態脂質奈米粒的優點。本實驗將以不同種類之非離子型界面活性劑,分別為辛基/癸基葡萄糖苷(P-810)與Tween 80 (T-80)對SLNs之粒徑與穩定性之影響,結果顯示P-810使用較少之添加量即能得到粒徑小(約185 nm)且較穩定(靜置60天粒徑無顯著差異)之SLNs,螢光顯微鏡測定進一步證實SLNs成功地同時包覆疏水性與親水性藥物,最後選擇最穩定之配方(P2)進行包覆藥物並進行包覆率測定,結果顯示,RP包覆率約87%,Vit B3則約32% 。未來研究目標將設法改善其包覆率,以符合化妝品/藥品傳輸系統之應用。
In this study, solid lipid nanoparticles (SLNs) were prepared by w/o/w double emulsified technique via a two-stage sonication method to encapsulate both a hydrophobic drug (retinyl palmitate, RP) and a hydrophilic drug (nicotinamide, Vit B3). The advantage of the current method is to obtain a smaller particle size and more stable SLNs without adding organic solvents. Caprylyl/capryl glucoside (Plantacare® 810, P-810) and Tween 80 (T-80) were used as hydrophilic emulsifiers to understand their effects on the particle size and stability of SLNs. Compared with T-80, the results showed that P-810 was able to obtain smaller nanoparticles of SLNs (~ 185 nm). Moreover, it formed a stable SLNs system (no significant difference in particle size after 60 days of storage at 4oC) with less amount of surfactants adding. Fluorescence microscopy of SLNs further confirmed that the hydrophobic and hydrophilic drugs were both successfully incorporated. Finally, an optimal formula P2 was chosen to determine the encapsulation efficiency. The results showed that encapsulation efficiency of RP and Vit B3 were ~ 87% and ~ 32%, respectively. Future studies are needed to improve the encapsulation efficiency for the future applications as the cosmetic / drug delivery system.
