Chemical Injection

Glycerin
Similar to insulin injection, the use of synthetic glycerin instead of vegetable glycerin can greatly improve the quality and stability of the preparation. In addition to insulin-sensitive aldehydes and ketone impurities, glycerin oxidation products such as tri-carbon alkyd, lactic acid, formic acid, hydroxymalonic acid, and glyceric acid, these oxides will ultimately affect the pH of the preparation.

Vegetable glycerin is easily oxidized due to the large amount of unknown components. The acidic substances generated during the oxidation process will react with other compounds. In addition to changing the structure of the main ingredient, new impurities will be generated after degradation. Hence, the impurity content will increase with time.

Our glycerin product has obtained the registration number of the National Medical Products Administration (NMPA, i.e. formerly CFDA).

Propylene glycol
In addition to glycerin, propylene glycol is often an important excipient for chemical injections. We provide the same quality assurance for injection grade propylene glycol as glycerin products.
