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.

Safety related:
Taboo substances: strong oxidants, reducing agents;
Safety measures: Keep away from fire and heat sources, and prevent contact Strong oxidants and strong alkali should not be stored together. Avoid exposure to light and air. Pay attention to personal protection and avoid direct physical contact.
First aid measures: In case of skin or eye contact, flush body parts with water or saline; if ingested, induce vomiting. Seek medical attention and move away from the scene to fresh air. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.
Leakage treatment: Quickly evacuate irrelevant personnel to a safe area, cut off the source of fire, wear neat protective equipment, wear anti-static work clothes, and cut off the source of leakage as much as possible. Depending on the amount of leakage, use sand or other non-combustible materials to absorb or absorb, or flush with large amounts of water, and the flushing water will enter the sewage treatment system.
Fire-fighting measures: Use anti-soluble foam, carbon dioxide, dry powder, and sand to extinguish fires. Water can be used to keep containers cool at the fire site.
