Milk anhydride and gels and opalescent

The solubility of sodium chloride in water with the temperature change is small , and impurities such as sodium chloride , Calcium lactate  magnesium chloride, potassium chloride , potassium bromide , sodium bromide, the solubility increases with temperature increases. With fluids such as liquid temperature is too high when filtering impurities with liquid through the membrane , temperature decreases the solubility decreases, the formation of white spots, white and so on , the product yield decreased clarity of the production when sodium chloride injection should be cold with France as well.
Compound sodium lactate injection with liquid and activated carbon adsorption temperature is higher, zinc lactate clarity because weak acid salt sodium lactate as an alkali , high temperature can be polymerized into lactic acid , lactic acid anhydride and gels and opalescent .
