Polyvinylpyrrolidone CAS:9003-39-8 Product Introduction

Product name: Polyvinylpyrrolidone

CAS: 9003-39-8


MW: 16.04246

Appearance: white free-flowing powder or solid.


Crosslinked homopolymer of pure vinylpyrrolidone. A free-flowing white or nearly white powder with good hygroscopicity. There is a slight odor. It is insoluble in all common solvents such as water and ethanol and ether, so the range of molecular fish cannot be determined by Chemicalbook. However, it has the ability to complex with a variety of substances (such as various types of alcohols that cause the discoloration of beverages such as wine), which is comparable to polyvinylpyrrolidone (PVP). And because of its insolubility, it is easy to remove after filtration.

Polyvinylpyrrolidone Application:

1.Clarifying agent; pigment stabilizer; colloidal stabilizer. It is mainly used for clarification and quality stability of beer (the reference amount is 8-20g/100L, and it is filtered and removed after maintaining for 24 hours). It can also be used in combination with enzymes (protease) and protein adsorbents. It is also used as a stabilizer for clarifying wine and preventing discoloration (reference dosage is 24-72g/100L).

2.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.

3.Used as a stationary solution for gas chromatography

4.Widely used as thickener, emulsifier, lubricant and clarifying agent, also as a complex of sterilizing agent PVP-I

5.As colloid stabilizer and clarifying agent, it can be used for clarifying beer, and it can be used in moderation according to production needs.

6. Disinfectant for medical, aquaculture and animal husbandry. For disinfection of skin and mucous membranes.

7.PolyFilterTM molecules have amide bonds and adsorb hydroxyl groups on polyphenol molecules to form hydrogen bonds. Therefore, it can be used as a stabilizer for beer, fruit wine/wine, and beverage wine to prolong its shelf life and improve its transparency and color. and taste. The product has two specifications: disposable and recyclable. Disposable products are suitable for small and medium-sized enterprises. Renewable products require the purchase of special filtering equipment, but they can be recycled and are suitable for recycling in large breweries.

8.In daily cosmetics, PVP and copolymers have good dispersibility and film forming properties, and can be used as setting agents for styling liquids, hair sprays and mousses, sunscreens for hair conditioners, foam stabilizers for shampoos, and waves. Dispersants and affinity agents in styling and hair dyes. Add PVP to vanishing cream, sunscreen, and depilatory to enhance moisturizing and lubricating effects. Taking advantage of the excellent surface activity, film-forming properties of PVP, and no irritation to the skin, no allergic reaction, etc., it has broad prospects in the application of hair care products, skin care products, etc.

10.Used to absorb phenols and tannic acid from water extracts to purify plant enzymes. Used as a chromatographic adsorbent to separate aromatic acids, aldehydes, and phenols. Used for clarification of beer and wine.
