1. Main active ingredients

Complex of 1-vinyl-2-pyrrolidone homopolymer and iodine. Calculated as dry product, the content of available iodine (I) should be 9.0% to 12.0%.

2. Traits:

Yellow-brown to red-brown amorphous powder. It is soluble in water or ethanol, but insoluble in ether or chloroform.

3. Identify：

Take about 0.5g of this product, add 5ml of water to dissolve, and test according to the following method.

(1) Take 1 drop of the solution, add 9ml of water and 1ml of starch indicator solution, it will appear dark blue.

(2) Take 0.5ml of the solution, spread it on a glass plate with an area of about 7.5cm×2.6cm, and place it overnight at low humidity and room temperature to dry, forming a brown, dry film that is easily soluble in water.

Mechanism of action:

PVP-I functions as an antiseptic through several mechanisms and is considered to have the broadest spectrum of action compared to other common antiseptics such as chlorhexidine. The two most potent antiseptic metabolites of PVP-I are molecular I2 and hypoiodous acid, which deliver free iodine. These free iodine molecules oxidize amino acids, nucleic acids and cell membranes. Through oxidation of cell surface receptors, PVP-I prevents the attachment of viruses to cellular receptors.
