Product Overview:
Propylene Glycol (1,2-Propanediol) is a versatile and widely used industrial diol with excellent viscosity, hygroscopicity, and solvent properties. It is an important raw material in the production of various resins, including unsaturated polyesters, epoxy resins, and polyurethane resins. With its diverse applications across multiple industries such as food, pharmaceuticals, cosmetics, and chemicals, Propylene Glycol serves as a critical ingredient in the formulation of numerous products, including lubricants, antifreeze, and emulsifiers.
Key Features and Applications:
Chemical Industry Applications:
Resin Production: Propylene Glycol is widely used in the production of unsaturated polyesters, epoxy resins, and polyurethane resins. These resins are integral to the manufacturing of coatings, adhesives, and composite materials used in various industrial applications.
Plasticizers & Surfactants: As an essential raw material, Propylene Glycol is used in the formulation of plasticizers and surfactants, enhancing product performance in diverse applications, from plastics production to cleaning agents.
Food Industry:
Food Emulsifier: In the food industry, Propylene Glycol is primarily used as a food emulsifier, helping to stabilize mixtures of ingredients that would otherwise separate, such as oil and water. It is found in a variety of food products, including salad dressings, flavorings, and sweeteners.
Humectant: It acts as a humectant, helping maintain moisture levels in foods, which enhances texture and prevents drying out, especially in baked goods.
Pharmaceutical Industry:
Solvent & Excipient: In pharmaceuticals, Propylene Glycol is commonly used as a solvent and excipient in the preparation of various ointments, creams, and lotions. It facilitates the dissolution of active ingredients, improving the consistency and stability of topical formulations.
Softener & Carrier: It is also used as a softener in topical products, improving their application and absorption properties. In some formulations, Propylene Glycol acts as a carrier for active ingredients, enhancing their delivery and effectiveness.
Cosmetic Industry:
Moisturizer & Stabilizer: In the cosmetic industry, Propylene Glycol is a popular ingredient in moisturizers, lotions, and skin care products due to its ability to retain moisture and provide a smooth, hydrating effect. It also helps stabilize formulations by preventing the separation of ingredients.
Solvent in Cosmetics: It is also used as a solvent in perfumes, shampoos, and other personal care products, ensuring the uniform distribution of ingredients and enhancing the overall product experience.
Antifreeze & Lubricants:
Antifreeze: Propylene Glycol is commonly used in antifreeze formulations for automotive, industrial, and HVAC systems. It lowers the freezing point of water, preventing freezing in cold temperatures while also providing corrosion protection.
Lubricant: It is used as a lubricant in various industrial applications due to its ability to reduce friction and wear in machinery, ensuring smoother operation and longer service life.
Desiccant:
Propylene Glycol is also utilized as a desiccant, effectively absorbing moisture in various applications, from packaging to chemical manufacturing.
Safety and Handling Information:
Safety: Propylene Glycol is generally recognized as safe (GRAS) for use in food and pharmaceuticals at prescribed concentrations. However, exposure to large quantities can cause irritation to the skin, eyes, and respiratory system. Appropriate personal protective equipment (PPE) such as gloves, goggles, and respirators should be worn during handling.
Environmental Impact: Propylene Glycol is biodegradable and poses minimal environmental risk when disposed of properly. However, care should be taken to avoid large discharges into water systems to prevent contamination.
Packaging and Storage:
Packaging Sizes: Available in bulk containers, drums, and smaller packaging for industrial and commercial use.
Storage Recommendations: Store in a cool, dry place, away from direct sunlight and sources of heat. Keep containers tightly sealed to prevent moisture absorption and degradation of the product.
Certificates:
Payment terms: Various payment methods are available, including T/T IN ADVANCE, Part repayment and part credit, etc.
