For professionals in the beverage and pharmaceutical industries, understanding the detailed specifications of ingredients is crucial for ensuring product quality, safety, and efficacy. Crosslinked Povidone (PVPP) is a highly specialized polymer with specific characteristics that dictate its performance. NINGBO INNO PHARMCHEM CO.,LTD. provides PVPP with comprehensive specifications and certifications to meet the rigorous demands of these sectors.

The appearance of PVPP is typically a White powder. This visual characteristic is an initial indicator of purity and proper manufacturing. Crucially, PVPP is known for its insolubility in water, acid, alkali, and common organic solvents, a key property that distinguishes it from standard Povidone (PVP) and enables its use as an effective insoluble adsorbent and stabilizer. This insolubility is vital for applications where the polymer needs to be easily removed after performing its function.

Key specifications for PVPP often include its grade, such as Food Grade, USP, EP, or BP, which denotes compliance with regulatory standards for ingestion and pharmaceutical use. Purity levels are also critical; for instance, the article mentions a purity of '>=95%'. Other important parameters include loss on drying (which should be minimal, e.g., '<=5%'), residue on ignition (typically '<=0.1%'), and nitrogen content (often within the range of 11.0-12.8%). The presence of specific impurities, like Impurity A, is also closely monitored, with limits set at low parts per million (e.g., '<=10ppm').

Certifications play a significant role in the selection of PVPP suppliers. NINGBO INNO PHARMCHEM CO.,LTD. highlights certifications such as GMP, DMF, Kosher, and Halal, which are essential for manufacturers in regulated industries. These certifications assure users of the product's safety, quality, and suitability for specific markets and applications. The shelf life of PVPP is typically 3 years when stored correctly, ensuring a reasonable usability period for bulk purchases.

When considering the purchase of PVPP, understanding these specifications allows formulators to select the most appropriate grade for their needs. Whether it's for clarifying wine or beer, or acting as a disintegration agent in tablets, adhering to recommended specifications ensures optimal performance. The wholesale price of PVPP from reputable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. provides excellent value for the quality and compliance offered.

In conclusion, a thorough understanding of PVPP specifications, including its physical form, purity, compliance with pharmacopoeial standards, and relevant certifications, is fundamental for its successful application. NINGBO INNO PHARMCHEM CO.,LTD. serves as a reliable partner, providing detailed product information to support its customers' manufacturing processes.
