Abstract

In this study, the formation potential and the stability of nano-emulsions were evaluated according to the structure of various cosmetic oils in Tween 80/Span 80 system using PIC method at 80 oC LP 70, Isopar H and Pripure 3759 of hydrocarbons were both form a stable nano-emulsion, particle size distribution of about 40 nm. A linear structure of silicone oil formed an unstable emulsion, but cyclic or short chain oil formed was a stable nano-emulsion. In ester oils, the particle size of emulsions increases with increasing molecular weight of oils and a stable nano-emulsion could not be obtained in the molecular weight of about 450. The particle size of the nano-emulsion against required HLB value for calculating in consideration of the lipophilic and hydrophilic oil was smaller in the HLB of 8-10.

본 연구에서는 Tween 80/Span 80의 유화계에서, PIC(Phase Inversion Composition) 방법으로, 80 oC에서 화장품용 오일의 나노에멀젼 형성 가능성과 오일의 구조에 따른 나노에멀젼의 안정성에 대하여 평가하였다. 탄화수소 계열의 LP 70, Isopar H 및 Pripure 3759는 모두 입도 분포가 40 nm 내외의 안정한 나노에멀젼을 형성하였다. 직쇄 구조의 실리콘 오일은 불안정한 에멀젼을 형성하였으나 환상 또는 짧은 사슬의 실리콘 오일은 안정한 나노에멀젼을 형성하였다. 에스테르 오일류에서는 분자량이 증가함에 따라 입도가 증가하였고 분자량이 약 450 이상에서는 안정한 나노에멀젼을 얻을 수 없었다. 오일의 친수성과 친유성을 고려하여 계산하는 요구 HLB (Hydrophilic Lipophilic Balance) 값에 대한 나노에멀젼의 입도는 HLB 값이 8-10 정도 범위에서 가장 입도가 작았다.
