Application areas

Application areas	Application Notes
1.Food and beverage industry：	As a food additive, humectant, and solvent, it can enhance the texture of food and keep it moist. It is widely used in food processing, such as in the production of candy, bread, and biscuits, and in the production of seasonings and flavorings.
2.Industrial manufacturing：	As a coolant and antifreeze, it lowers the freezing point of the liquid and prevents the cooling system from freezing. It is commonly used in automobiles, industrial equipment, and air conditioning systems to ensure that the liquid can still flow under cold conditions.
3.Pharmaceutical manufacturing：	As a carrier for drugs and vaccines, propylene glycol stabilizes and extends the shelf life of medications. In pharmaceutical processes, it serves as a solvent and diluent, and also plays a role in regulating temperature and humidity in pharmaceutical products.
4.Daily chemical industry：	It possesses moisturizing and solvent properties, making cosmetics easier to apply and absorb. It can be added to skincare, cosmetic, and personal care products such as lotions, creams, and lipsticks.

Packaging

ton containers, leather drums, tank trucks

Stability and storage conditions

Propylene glycol is hygroscopic and should be stored in a tightly closed container in a cool, dry place, away from direct sunlight. Keep away from open flames, heat sources, and oxidizers.
