1. Povidone k30 Introduction:

Povidone k30 has the molecular formula of (C6H9NO)n and appears as a white to slightly off-white powder. Povidone formulations are widely used in the pharmaceutical industry due to their ability to dissolve in both water and oil solvents. The k number refers to the mean molecular weight of the povidone. Povidones with higher K-values (i.e., k90) are not usually given by injection due to their high molecular weights. The higher molecular weights prevent excretion by the kidneys and lead to accumulation in the body. The best-known example of povidone formulations is povidone-iodine, an important disinfectant.

2. Povidone k30 Functions & Properties

Polyvinylpyrrolidone is readily soluble in water, physiologically compatible, non-toxic, essentially chemically inert, temperature-resistant, pH-stable, non-ionic, and colorless. This remarkable combination of properties predestined its use in numerous applications in medicine, pharmaceutical, cosmetics, food and many other industry.

The unique properties of polyvinylpyrrolidone, such as its high solubility in solvents of differing polarities, its solubilizing and film-forming abilities, its suspension and emulsion-stabilizing effects and, last but not least, its binding properties,make it one of the most important excipients in pharmaceutical technology.

Povidone K30 is used in the pharmaceutical industry as a synthetic polymer vehicle for dispersing and suspending drugs. It has multiple uses, including as a binder for tablets and capsules, a film former for ophthalmic solutions, to aid in flavoring liquids and chewable tablets, and as an adhesive for transdermal systems.
