Application Fields
Application Field | Application Description |
Food and Beverage Industry | As a food additive, humectant, and solvent, it can enhance the taste of food and maintain moisture. Widely used in food processing, such as making candies, bread, biscuits, etc., and used in the production of condiments and flavorings. |
Beverage Industry | Juices and soft drinks: Adding sorbitol solution can provide moderate sweetness to juices and soft drinks without introducing additional sugar and calories. Coffee and tea beverages: As a sweetener for coffee or tea, sorbitol solution is suitable for those seeking low-sugar, low-calorie drinks. |
Manufacturing Industry | As a coolant and antifreeze, it lowers the freezing point of liquids, preventing the cooling system from freezing. Commonly used in automobiles, industrial equipment, and air conditioning systems to ensure fluid flow under cold conditions. |
Pharmaceutical Manufacturing | As a carrier for drugs and vaccines, it stabilizes and extends the shelf life of medications. In pharmaceutical processes, propylene glycol is used as a solvent and diluent, while also regulating temperature and humidity in medical products. |
Daily Chemical Industry | With moisturizing and solvent properties, it makes cosmetics easier to apply and absorb. Added to skincare products, cosmetics, and personal care products, such as lotions, creams, lipsticks, etc. |
Industrial Manufacturing | As a solvent and intermediate in reactions, used in the synthesis of various chemical products. Widely applied in synthetic resins, coatings, paints, solvents, and polymers. |
Packaging Methods
Tonnage drums, plastic drums, tank trucks, and kraft paper bags
Stability and Storage Conditions
Propylene glycol is hygroscopic and should be stored in sealed containers, such as glass, plastic, aluminum, and stainless steel containers, placed in a cool, dry place, avoiding direct sunlight. Propylene glycol is a flammable liquid, so fire safety regulations should be followed during storage and handling. Keep away from open flames, heat sources, and oxidizing agents.
