Abstract

Cellolose nanoparticles loaded with retinyl palmitate were prepared by modified spontaneous emulsification solvent diffusion method. We used polysorbate 20, polysorbate 60, and PPG-26-Buteth-26/PEG-40 Hydrogenated castor oil as dispersion medium. The optimum condition for particle size of cellulose nanoparticles was 1w/v% ethyl cellulose with, 3w/v% polysorbate 60 solution. And The optimum condition for leading amount of retinyl palmitate of cellulose nanoparticles was 2w/v% ethyl cellulose with 1w/v% polysorbate 60 solution. Also, we found that this optimum condition can be applicable to other active compounds.

생체 친화성 에칠셀룰로오스 막제를 사용하여 자발적인 유화확산에 의하여 레티닐 팔미테이트를 봉입한 나노입자를 제조하였다. 분산매인 유화제로는 폴리소로베이트 20, 폴리소르베이트 60, 피피지 26-부테스-26/피이지-40 하이드로제네이티드캐스터오일를 이용하여 제조하였으며, 본 결과로서 나노크기 입자를 제조하기에 가장 적절하며 안정한 조건은 1w/v% 에칠셀룰로오스와 3w/v% 폴리소그베이트 60 수용액을 이용한 것이었으며, 레티닐 팔미테이트의 봉입률을 최대화하기 위한 조건은 2w/v% 에칠셀룰로오스와 1w/v% 폴리소르베이트 60 수용액을 이용한 제조 조건이었다. 또한 이 최적 조건에 다른 유효성분에도 적용 가능한 것을 확인하였다.
