Objective: Rice bran oil contains several bioactive components that exhibit antioxidant properties
such as tocopherol, tocotrienols and gamma-oryzanol. Liposomes have been used to carry
these bioactive compounds in order to increase their stability and activity [1]. The
aim of this study was to develop lipstick formulations containing rice bran oil liposome
[2].
Method: Lipstick containing rice bran oil liposomes were prepared by fusion method. The lipstick
formulations were evaluated for their appearance, pH, stability under freeze-thaw
condition, bioactive release using dissolution test determined in term of antioxidant
activity.
Results and Conclusion: The Lipstick formulation containing 5.0% of rice bran oil liposome showed good physical
characteristic. Only little change of appearance and pH were observed. This formulation
showed statistically antioxidant activity higher than lipstick formulation containing
3.0% of rice bran oil. The result suggests that the suitable formulation in this study
is lipstick containing 5.0% of rice bran oil liposome. This formulation has a potential
to be used for cosmetic products.
