Propylene glycol is an organic compound (diol), usually slightly Sweet, odorless, colorless and transparent oily liquid, hygroscopic and easily mixed with water, acetone, and chloroform. Propylene glycol has a wide range of applications and is often used as a hygroscopic agent, antifreeze, lubricant and solvent in the food, pharmaceutical and cosmetic industries. Propylene glycol supply points out: Propylene glycol, which is widely used in various industries, is divided into two types: 1,2-propanediol and 1,3-propanediol. 1,2-Propylene glycol has good viscosity and hygroscopicity and is widely used in the food, pharmaceutical and cosmetic industries.
Propylene glycol has bacteriostatic and sterilizing effects:
As a bacteriostatic agent, propylene glycol is similar to ethanol, and its mold-inhibiting effect is similar to that of glycerin, slightly lower than Ethanol;
Propylene glycol is extremely stable at room temperature, but is oxidized when left open at high temperatures (above 280°C); it is chemically stable after being mixed with 95% ethanol or water; it can be autoclaved or filtered Over-sterilized;
Propylene glycol has excellent sterilization ability. It can be used as a preservative and sterilizer for canned fruits, jams, pickled products, ham and sausages;
When propylene glycol When the concentration is above 10%, it can prevent the reproduction of mold in liquid foods, which is effective for the preservation of packaged foods and syrups on the table.
