Propylene Glycol (CAS 57-55-6) - Industrial Applications
Propylene Glycol is a colorless, odorless, hygroscopic liquid widely utilized as a solvent, humectant, and carrier across diverse industries. With high purity (≥99.85%) and exceptional versatility, it serves as an essential ingredient in pharmaceutical formulations, food processing, cosmetic products, and industrial applications. Its molecular formula is C₃H₈O₂, with a molecular weight of 76.09 g/mol.
• Pharmaceutical Industry Applications
Functions as an FDA-approved solvent, humectant, and stabilizer in oral, topical, and injectable pharmaceutical formulations. Its superior solvency properties enhance drug delivery systems while maintaining formulation stability across wide temperature ranges. Classified as Generally Recognized as Safe (GRAS) for pharmaceutical use.
Productos finales: Injectable solutions, oral syrups and suspensions, topical creams and ointments, capsule preparations, nebulizer solutions, artificial tears
• Food & Beverage Industry Applications
Serves as an FCC-certified food additive (E1520) functioning as a humectant, solvent, and carrier for flavors, colors, and preservatives. Maintains optimal moisture content, prevents crystallization, and extends shelf life in processed foods and beverages. Designated as GRAS by the FDA with an acceptable daily intake of 25 mg/kg body weight.
Productos finales: Baked goods, ice cream and frozen desserts, condiments and seasonings, beverage concentrates, food colorants, flavor extracts and essences
• Cosmetics & Personal Care Applications
Acts as a multifunctional ingredient serving as a humectant, solvent, skin conditioning agent, and viscosity-decreasing agent in cosmetic formulations. Enhances product texture, improves spreadability, and facilitates penetration of active ingredients. Approved for use up to 50% concentration in cosmetic products by the Cosmetic Ingredient Review (CIR).
Productos finales: Facial moisturizers and serums, body lotions and creams, shampoos and conditioners, toothpaste, deodorants and antiperspirants, makeup products (foundation, lipstick)
• Industrial Applications
Utilized as a heat transfer fluid, antifreeze component, and chemical intermediate in various industrial processes. Approximately 45% of global propylene glycol production serves as a feedstock for unsaturated polyester resin (UPR) manufacturing. Also employed in polyurethane production, aircraft de-icing formulations, and HVAC systems requiring low-toxicity antifreeze solutions.
