At NINGBO INNO PHARMCHEM CO.,LTD., we understand that sourcing the right pharmaceutical excipients is paramount to successful drug development. Polyvinylpyrrolidone K30 (PVP K30) is a cornerstone ingredient, and understanding its properties, specifications, and proper sourcing is crucial for every formulator.

PVP K30 is characterized by its appearance as a white to milky, hygroscopic powder with a faint odor and taste. Its water solubility is a key attribute, along with its solubility in various polar organic solvents like ethanol and trichloromethane. In contrast, it remains insoluble in less polar solvents such as acetone and ether. This solubility profile dictates its utility in diverse formulation types, particularly in aqueous systems.

A critical aspect for pharmaceutical use is its compliance with pharmacopeial standards. Our PVP K30 meets rigorous requirements set by the United States Pharmacopeia (USP), British Pharmacopoeia (BP), European Pharmacopoeia (EP), and Chinese Pharmacopoeia (CP). This includes specific limits for pH (3.0-5.0), water content (≤5.0%), residue on ignition (≤0.1%), aldehydes (≤0.05%), and residual 2-Pyrrolidone (≤0.001%). The K-value, a measure of its viscosity and molecular weight, typically falls within the 27-32 range for the K30 grade, ensuring consistent performance as a binder, suspending agent, and dissolution enhancer.

The role of PVP K30 as a dissolution enhancer is vital for poorly soluble drugs, improving their absorption and bioavailability. As a suspending agent, it maintains the homogeneity of liquid formulations, preventing particle settling and ensuring accurate dosing. In tablet manufacturing, it serves as a highly effective tablet binder, promoting tablet integrity and appropriate disintegration. These functions collectively contribute to the overall quality and efficacy of the final pharmaceutical product.

When you need to buy PVP K30 online, choosing a reputable PVP K30 supplier like NINGBO INNO PHARMCHEM CO.,LTD. is essential. We ensure that our product undergoes stringent quality control processes to guarantee compliance with all pharmacopeial specifications. Understanding these specifications, such as residual monomer levels and K-value ranges, allows formulators to predict and optimize its performance in their specific applications.

In summary, Polyvinylpyrrolidone K30 is a highly versatile and essential pharmaceutical excipient. Its consistent properties, broad solubility, and compliance with global pharmacopeias, coupled with its effectiveness as a binder, suspending agent, and dissolution enhancer, make it an indispensable ingredient. Sourcing high-quality PVP K30 from trusted providers like NINGBO INNO PHARMCHEM CO.,LTD. is key to successful pharmaceutical formulation.
