| 要約: | The ability of chitosan to form edible films can be applied as sunscreen
and antioxidants. Chitosan in the form of nanoparticles will increase the
effectiveness as a sunscreen and antioxidants. The aims of this research is to
obtain the optimum formula nanochitosan o/w cream and knowing the physical
properties and stability, also its activity as sunscreen and antioxidants.
Nanochitosan formulated in o/w cream with the composition of stearic
acid, cetyl alcohol and TEA as an emulsifier which is optimized using Simplex
Lattice Design. All formulas are tested its physical properties, including viscosity,
dispersive power, and adhesion power to obtain optimum formula. Optimum
formula cream with varying nanochitosan composition is 0,1% (A)
