Abstract:
The aims of this study were to develop the blank noisomal formulation with good physical stability and prepare the niosomes loaded with acetyl hexapeptide for cosmetic utilization. In addition, the physicochemical characteristics of niosomes loaded with acetyl hexapeptide were performed. The blank niosomal formulation, which was consisted of Brij®L4/ cholesterol/cetyl trimethyl ammonium bromide (CTAB) in the malar ratio of 1.025:1.025:0.05, was loaded with 0.5 mg/ml acetyl hexapeptide solution at 5%. The vesicular size of niosomes loaded with acetyl hexapeptide was 763.80±131.19 namometer, whereas the zeta potential value was 66.80±4.03 millivolt. After keep the niosomes loaded with acetyl hexapeptide at 4 storage conditions, including room temperature, 4 and 45°C, and 7 cycles of heating-cooling cycle, the changed physical characteristics of each formulation were less than 30%. For chemical stability evaluated by Bradford dye assay, acetyl hexapeptide loaded in niosomes was shown the remaining protein content greater that in solution, particularly in the storage condition at 45°C and 7 cycles of heating-cooling cycle.
