Polypropylene Glycol (PPG) is not a one-size-fits-all chemical. Available in various grades, each with distinct molecular weights and purity levels, PPG's performance characteristics can be significantly tailored for specific applications. As a specialized supplier and manufacturer of chemical intermediates, NINGBO INNO PHARMCHEM CO.,LTD. provides a comprehensive range of PPG grades to meet the diverse needs of industries from pharmaceuticals to advanced lubricants.

The key differentiator among PPG grades is their molecular weight, often indicated by numbers like PPG-200, PPG-400, PPG-1000, and so forth. Lower molecular weight PPGs (e.g., PPG-200 to PPG-400) tend to be less viscous and more water-soluble, making them excellent choices as emollients and humectants in cosmetic formulations. They contribute to skin hydration and improve product texture. Their properties as emulsifiers and stabilizers are also beneficial in creams, lotions, and hair conditioners. For cosmetic formulators, understanding these grade-specific benefits is crucial for product efficacy.

As the molecular weight of PPG increases, its viscosity rises, and water solubility generally decreases. Higher molecular weight grades, such as PPG-1000 or PPG-2000, are often preferred for industrial lubricant applications. They provide enhanced viscosity stability, thermal stability, and superior lubricating properties under demanding conditions. These grades are vital for applications requiring robust performance in machinery, where maintaining lubrication under pressure and varying temperatures is paramount. When sourcing PPG for industrial lubricants, selecting the appropriate molecular weight is key to achieving the desired performance characteristics.

In the pharmaceutical industry, the purity of PPG is as critical as its molecular weight. Pharmaceutical-grade PPG must meet stringent regulatory standards for safety and efficacy. It functions as a solubilizer, stabilizer, and excipient in various drug delivery systems, including topical ointments and injectables. Procurement managers and pharmaceutical researchers must ensure they are sourcing PPG that adheres to USP/EP standards. As a trusted manufacturer, we offer pharmaceutical-grade PPG, ensuring the quality and compliance necessary for drug development and manufacturing.
