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.
