Application
1). Serves as a versatile solvent in paints, coatings, and adhesives due to its ability to dissolve resins and improve film formation.
2). Used in antifreeze formulations for vehicles and industrial systems, providing freeze protection while maintaining low toxicity compared to ethylene glycol.
3). Acts as a humectant and plasticizer in textiles, paper, and leather processing to retain moisture and enhance flexibility.
4). Approved as a food additive (e.g., E number E1520) for its emulsifying, stabilizing, and moisture-retaining properties. Commonly found in processed foods, baked goods, and beverages to prevent spoilage and maintain texture.
5). Used in food-grade antifreeze systems for equipment in cold storage or beverage production.
6). A key ingredient in topical creams, lotions, and oral medications as a solvent, humectant, and viscosity regulator.
7). Used in inhalers and nebulizers to dissolve active pharmaceutical ingredients (APIs) and improve drug delivery.
8). Functions as a preservative in cosmetics to inhibit microbial growth in water-based formulations.
9). Used as a feed additive to prevent mold growth and maintain moisture in animal feed.
10). Applied in veterinary medications as a solvent or carrier for active ingredients.
Storage
1). Environmental Conditions: Store in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Maintain temperatures below 30°C (86°F) to prevent degradation or vaporization.
2). Container Requirements: Use tightly sealed, corrosion-resistant containers (e.g., steel or high-density polyethylene drums) to avoid contamination and moisture absorption. Ensure containers are labeled clearly and kept closed when not in use.
3). Safety Precautions: Separate from strong oxidizing agents, acids, and alkalis, as these may react with propylene glycol. Avoid prolonged contact with incompatible materials. Keep away from ignition sources (e.g., sparks, flames) due to its low flammability.
Stability
1). Chemical Stability: Propylene glycol is generally stable under normal storage and use conditions when kept away from extreme temperatures and incompatible substances. It is resistant to hydrolysis and oxidation in moderate environments.
2). Incompatible Substances: Reacts with strong oxidizing agents (e.g., chromic acid, nitric acid), which may cause exothermic reactions or combustion. Avoid contact with dehydrating agents (e.g., sulfuric acid) or strong bases, which could initiate esterification or other chemical changes.
3). Degradation Pathways: Prolonged exposure to high heat (above 100°C) may lead to decomposition, producing irritating fumes such as propionaldehyde or acrylic acid. In biological systems, it is metabolized into lactic acid, which is non-toxic in moderate amounts.
4). Shelf Life: When stored properly, propylene glycol has a long shelf life (typically 2–3 years), with minimal degradation under recommended conditions.
