Objective:To study the rheology behavior of vitamin A palmitate gel and establish a method to measure its dynamic viscosity with a cone-plate rheometer.Method:A Brookfield R/S CPS rheometer was used to develop the method with C-50-1 rotor at the Shear-Rate 80(s-1).Temperature when the test was carried out was 20 ℃.Results:The average dynamic-viscosity of vitamin A palmitate gel is 867 mPa·s(RSD=0.29%,n=30).Conclusion:The method is convenient,accurate,reliable and suitable for the determination of the dynamic-viscosity of the gel.
