| Uses | It is the main raw material of unsaturated polyester, epoxy resin and polyurethane resin; Propylene glycol has good viscosity and hygroscopicity, and is non-toxic. It is widely used as a moisture absorbent, antifreeze, lubricant and solvent in the food, medicine and cosmetic industries; In the food industry, it is an excellent solvent for seasonings and pigments. In medicine, it is a solvent, softener and excipient for making various humidizer and humectant; propylene glycol has good mutual solubility with various spices, so it can also be used as a solvent and softener for cosmetics; it can also be used as a tobacco moisturizer, moisturizer, antimildew agent, food processing equipment lubricating oil and food marking ink solvent, propylene glycol aqueous solution is an effective antifreeze. It is also a raw material for plasticizers, surface active agents, food emulsifiers, demulsifiers, fruit ripening agents, preservatives, hygroscopic agents, lubricants, and antifreeze agents. | ||
| Hazard category | General chemicals | ||
| Fire-fighting measures | Use alcohol-resistant foam, carbon dioxide, dry powder, sand to extinguish the fire, and use water to keep the container cool when it is critical. | ||
| Emergency treatment | Non-toxic, if splashed on the skin or clothes, rinse with water, splash in the eyes with running water or normal saline. | ||
| Packaging, storage, transportation | It can be packed in galvanized iron drum (200-215kg/drum), plastic drum (200-215kg/drum), IBC (ton drum), liquid bag, stainless steel tank; because propylene glycol is easy to absorb moisture, it should be stored in a closed container in a dry place, The shelf life of airtight barrels is one year, the storage effect of atmospheric tanks is not as good as barrels, and it is not suitable for long-term storage; transportation according to general cargo requirements. | ||
