Advantages of Insoluble Polyvinyl Pyrrolidone

Disintegration performance

It has strong water absorption and swelling properties, can quickly show high capillary activity and excellent hydration ability, can quickly allow water to enter the tablet, and promote rapid disintegration.

Adsorption capacity

In the food industry, it can adsorb polyphenols in beverages such as beer and juice to prevent turbidity and precipitation during storage, and improve the transparency, color and taste of beverages.

Excellent stability

It has high thermal stability and chemical stability, and can maintain its chemical structure and properties unchanged in a wide temperature and pH range.

High safety

It has excellent biocompatibility and does not cause any irritation to the skin, mucous membranes, eyes, etc. It is safe to use as a pharmaceutical excipient.

Application

Insoluble polyvinyl pyrrolidone has important applications in beer, wine, and fruit clarifiers, as follows:

Application in beer:
It is clearer and more transparent in appearance, and its storage stability has also been improved, which can effectively extend the shelf life of beer and keep the quality and taste of beer relatively stable for a long time.

Application in wine:
During the brewing process, wine will produce some proteins, tannins, pigments and other substances, which may interact with each other to form precipitation or make the wine turbid under certain conditions. Insoluble polyvinyl pyrrolidone can adsorb these impurities and remove them from the wine by precipitation or filtration, thereby improving the clarity of the wine.

Application in fruit:
After the fruit is squeezed, the juice will contain some pectin, protein, starch and other substances, which can combine with the substances in it to form larger particles, and then remove them by filtration or centrifugation, so that the juice becomes clear.

FAQ

1.Is insoluble polyvinyl pyrrolidone harmful to you?
This material is not considered to cause adverse health effects or skin irritation upon contact (classified using animal models). However, good hygiene practices require that contact be kept to a minimum and that appropriate gloves be used in occupational settings.

2. Is insoluble polyvinyl pyrrolidone an ingredient safe?
The Ingredient Safety Panel has evaluated the safety of insoluble polyvinyl pyrrolidone. The panel evaluated the scientific data and concluded that PVP (polyvinyl pyrrolidone) is safe for use in cosmetic and personal care products.

3. Is insoluble polyvinyl pyrrolidone the same as povidone?
Povidone, also known as polyvinyl pyrrolidone (PVP) or povidone, is a synthetic water-soluble polymer made from the monomer N-vinyl pyrrolidone and used as a binder in many pharmaceutical tablets and a lubricant in eye drops.

4. Is insoluble polyvinyl pyrrolidone edible?
The monomer is carcinogenic and highly toxic to aquatic life. However, pure PVP polymer is very safe and can be consumed by humans, and has been used as a plasma expander for trauma patients since the first half of the 20th century.

5. Can you be allergic to insoluble polyvinylpyrrolidone?

Several cases of allergic reactions to polyvinylpyrrolidone (PVP) have been reported. Most cases occurred in adults and after applying povidone-iodine solution to the skin or mucous membranes.
