Additional Information: Polyethylene Glycol (PEG) is a series of high-stability water-soluble polymer auxiliary materials meeting international pharmacopoeia and food-grade standards, with multiple specifications differentiated by molecular weight. It features excellent water solubility, lubricity, moisturizing, dispersibility and chemical inertness, compatible with most pharmaceutical raw materials and formula systems. Low-molecular-weight PEG serves as solvent, solubilizer and humectant; high-molecular-weight PEG acts as tablet binder, lubricant, sustained-release matrix material and coating auxiliary. It is widely used in pharmaceutical preparations, nutritional health products, cosmetic moisturizing systems and food processing industries, with high safety and stable processing adaptability, being a mainstream multifunctional polymer auxiliary material.
