At Ningbo Inno Pharmchem Co., Ltd., we understand that the efficacy and safety of final products are directly tied to the quality of the raw materials used. Povidone K15, a critical component in many pharmaceutical and cosmetic formulations, demands stringent adherence to specifications and robust quality assurance processes. As a leading supplier, we ensure that our Povidone K15 meets the highest industry standards.

The technical specifications for Povidone K15 are comprehensive, covering key parameters that define its performance and suitability for various applications. The K value, typically ranging from 12.75 to 17.25 for Povidone K15, is a primary indicator of its molecular weight and solution viscosity. This parameter is crucial for formulators, as it dictates how the polymer will behave in their specific formulations, whether it's for thickening, film-forming, or binding. The NVP (N-vinylpyrrolidone) content, usually around 11.5-12.8%, is another critical indicator of the polymer's purity and consistency. Low moisture content (e.g., <5.0%) and residue on ignition (e.g., <0.1%) are also vital, ensuring that the product is free from unwanted impurities that could affect stability or performance.

Furthermore, strict limits on heavy metals (e.g., <10 ppm), aldehydes (e.g., <0.05%), and other potential contaminants like hydrazine and peroxides are essential, especially for cosmetic grade povidone K15 and pharmaceutical applications. These parameters are closely monitored through rigorous testing. For instance, the pH value, typically between 3-5, is checked to ensure compatibility with sensitive formulations. The shelf life of Povidone K15, generally around 3 years when stored properly, is also a testament to its stability. Adherence to these detailed specifications is why cosmetic grade povidone K15 is so reliable for advanced product development.

Quality assurance at Ningbo Inno Pharmchem Co., Ltd. involves more than just meeting these numbers. Our manufacturing facilities are certified with ISO 9001 for quality management and ISO 14001 for environmental management. We also hold certifications such as GMP, EP, Kosher, and HALAL, and are registered with the US FDA, including DMF. These certifications validate our commitment to producing high-quality, safe, and compliant ingredients.
