The temperature characteristics of "N-Butanol-Water-Tea oil-Saponin" microemulsion system were discussed by drawing three phase diagram and measuring electrical conductivity. The appearance, particle size and distribution of the microemulsion system were investigated. The system could form microemulsion. The average particle size of the droplet of the microemulsion system was 57 nm and the polydispersity index was 0.200. The formation capacity, stability and electrical conductivity of the system under different temperatures were analyzed. It wa...
