What Does PVP Stand For In Chemical Industrial?
 Polyvinylpyrrolidone (PVP), also commonly called Polyvidone,with the molecular formula (C6H9NOn, is a well known water soluble polymer compound, or a compound that has a long and repeating structure made from the monomer N-vinylpyrrolidone. Polyvinylpyrrolidone is a flaky substance when dry, can absorb a large amount of water, and is lethally toxic to aquatic life.

This polymer was discovered in 1939 by Walter Reppe and because of its bonding abilities it has been used in many industries since then.In 1939, Reppe, who was working with the N vinylpyrrolidone  monomer (NVP),discovered the polyvinylpyrrolidone compound. Known for his work with acetylene chemistry, or the hydrocarbon acetylene, he thought of PVP as one of the more interesting derivatives he discovered; so, he patented it. The substance was first used as a substitute for blood plasma. PVP, when dry, is a flaky substance, and it is able to dissolve in water.PVP is extremely toxic and will almost instantly kill the organisms.The medical field uses polyvinylpyrrolidone as a blood plasma expander, but it is found more often in medical tablets as a relatively safe binding agent. Other industries use this as a metal quencher and a food stabilizer.

Polyvinylpyrrolidone is ususlly still used in conjunction with blood plasma, but not as a substitute. It works more as an expander to help trauma victims with extreme blood loss. More often, PVP is used in oral tablets that are safe when used as directed. If someone abuses tablets containing PVP, especially if the tablet is injected rather than taken orally, then PVP can cause pulmonary vascular injury, which can be lethal.Many common care products use povidoneas a binding agent to keep the other components stable and together. Toothpaste, hair spray and shampoo are three examples of this. Other common products that contain PVP are adhesives that need to be moistened before they activate, such as those on stamps and envelopes.

The food industry also uses polyvinylpyrrolidone. In foods that need stabilizers  mostly processed foods PVP acts as the stabilizer and settles all components so they work together. The wine industry, specifically white wine, uses this as a fining agent, or a substance that gets rid of unwanted sediment and organic compounds.
