Pure lactic acid is a colorless liquid, is a colorless to pale yellow liquid. Odorless, hygroscopic. The relative density of 1.2060 (25/4 ℃). Melting point 18 ℃. Boiling point 122 ℃ (2kPa). Refractive index nD (20 ℃) ??1.4392. With water, ethanol, glycerin, insoluble in chloroform, carbon disulfide and petroleum ether. Heating under normal pressure, concentrated to 50%, part of the anhydride into milk, thus products often contain 10% -15% of the milk anhydride.

Lactic acid is mainly pharmacological effects
Its pharmacological effects are: ① in the intestinal wall can be formed on the surface protective layer, effectively blocking pathogens and viruses; ② can stimulate the intestinal tract to produce antibodies, thereby improving their intestinal immune function; ③ able to protect and promote the intestine growth of beneficial bacteria that selectively kills the pathogen; ④ can regulate intestinal water and electrolyte balance; ⑤ can promote gastric acid secretion, enhance digestion. When using Sodium lactate films, should be strictly in accordance with the right approach to take, if unauthorized changes taking method, it will weaken the efficacy. So, taking lactobacillus films, should pay attention to what matters it? First, ferrous lactate tablets to chew some people feel Juefu drug smells bad, it is direct water delivery service. In fact, doing so on the efficacy of the play is very unfavorable. Because lactobacillus tablets in the mouth when chewed saliva sufficiently mixed to form a paste, which makes the drug into the gastrointestinal tract to the rapid decomposition, directly enhance the acidity of the intestines, which can inhibit the propagation of intestinal pathogens . Moreover, the fermentation of lactic acid can be reduced saliva and gas effects play a role in the drug speed.
