Effect of Lecithin on Safety of Composition B

摘要

By means of experiments of emulsification, stability and observations of microscope photographs, it shows that mixture of NC and lecithin can emulsify wax very well in composition B. Two kinds of lecithin which can avoid composition B changing color are found. Using DSC, Bruton pressure gauge, VST and sensitivity test, the effect of the mixture of NC and lecithin on the safety of composition B is evaluated.
