Abstract

Abstract: In order to achieve a wide range of applications in many fields, especially on oil body as a substrate carrier system of the foundation, extraction method of safflower oil and characteristics of safflower oil body lotion was researched. Extraction efficiency of safflower oil body was compared, including its value at different pH, NaCl concentration conditions, an average particle size of safflower oil and stability, as well as its viscosity to conduct investigations. Results showed that the safflower oil body dispersed more evenly, at pH≥6, the average particle size of 1.75-2.05 μm and pH ≤ 6 conditions, the average particle size of 1.50-1.75 μm; while NaCl concentration of 0.2 and 0.4 mg/mL, NaCl concentration 1.2 and 2.0 mg/mL, the safflower oil bodies appeared aggregation. When sucrose concentration between 0.1 and 0.2 mg/mL, safflower oil dispersion is uniform; when the sugar concentration of 0.4-1.0 mg/mL, safflower body intensive, with increasing concentration of sucrose, safflower oil body size gradually began to heterogeneity. The optimum extraction condition for safflower oil body is pH7, NaCl 0.2 mg/mL, sucrose concentration of 0.1 mg/mL. The study proved that safflower oil body without adding detergent or without physical approach, the saved is unstable.
