Objective ： To explore the influencing factors of melting point determination of white vaselin. Methods： Tianda Tianfa melting point instrument was used to measure the melting point of white vaselin, and to find the fac- tors that affected the repeatability and accuracy of melting point determination. Results： Through the experiments to draw the conclusion that the factors such as the amount and the shape of sample et al, directly affect the accuracy of the melting point. Condution： The influencing factors in the determination of the melting point of white vaselin should be controlled to improve the reproducibility and accuracy of the determination method.
