All products comply with Ph. Eur, USP/NF, JP,BP certificate of analysis.
Packed in 25 kg plastic drum or fiber drum, inner lined with PE bags. Special packing is available according to customer's requirement. Preserve in tight containers.
A1: Povidone (PVP K-series) is primarily used as a binder, film-former, and disintegrant in oral preparations. It is suitable for a variety of pharmaceutical applications, including tablets, capsules, and granules, ensuring improved dissolution rates and bioavailability of drugs.
A2: Povidone (PVP K15) has a pH range of 3.0 to 5.0, a K value between 12.75 and 17.25, and a water content of less than or equal to 5.0%. It contains less than 500 ppm of aldehydes and peroxides, and less than 1 ppm of hydrazine.
A3: All Povidone (PVP K-series) products comply with Ph. Eur, USP/NF, JP, and BP certificate of analysis, ensuring they meet international quality and safety standards.
A4: Povidone (PVP K-series) is packed in 25 kg plastic drums or fiber drums, inner lined with PE bags. It should be stored in tight containers to maintain its quality and stability.
A5: Povidone (PVP K-series) offers benefits such as improved dissolution rates, enhanced bioavailability, and increased stability of pharmaceutical formulations.
