Product Description
PVP K30 is also called polyvinylpyrrolidone K30 or polyvidone K30. It is a macromolecule polymer made from N-VinyPyrrolidone (NVP) through polymerization. Povidone K30's mean molecular weight is 40000. This product is white to off white powder, odorless, tasteless, soluble in water and ethanol, insoluble in acetone or ether. Its molecular formula is (C6H9NO)n, and its CAS number is 9003-39-8.
PVP K30 Powder has a hygroscopic nature with good adhesive properties, and it has stable PH value and has the ability to form transparent films. It is widely used in food, cosmetics, technical industry and so on.
Due to its adhesive properties and excellent water and alcohol solubility, povidone K30 can be widely used as:
3.1. Adhesives.
3.2. Binder for tablets, capsules and granules.
3.3. Coating agent.
3.4. Film forming agent.
3.5. Bioavailability enhancing agent.
3.6. Food stabilizer.
4. The role of PVP k30 in the food additives products:
5.As a synthetic water-soluble polymer compound, PVP has the general properties of water-soluble polymer compounds, such as colloid protection, film-forming, cohesiveness, hygroscopicity, solubilization or agglomeration. People pay attention to its excellent solubility and physiological compatibility. Among synthetic polymers, it is rare that PVP is soluble in water and most organic solvents, with low toxicity and good physiological compatibility, especially with in healthcare, food, and cosmetics, which are closely related to people's health.
Polyvinylpyrrolidone is a ketone organic compound, which can be used as clarifying agent; stabilizer; thickening agent; tableting filler; dispersing agent. Polymer PVP with a molecular weight of 360,000 is often used as a clarifying agent for beer, vinegar, and wine.
