Product nature
Polyvinylpyrrolidone (Polyvinylpyrrolidone) is a non-ionic water-soluble polymer, both within the molecule hydrophilic groups, and oleophilic groups, so that it is soluble in water, but also soluble in most organic solvents (such as alcohols, carboxylic acids, amines, halogenated hydrocarbons, etc.), very low toxicity, good physiological compatibility.
Povidone K30PVP-K30 polyvinylpyrrolidone thickening adjuvant 25kg/ barrel
The strain of pyrrolidone and ethylene were synthesized into vinylpyrrolidone monomer under pressure and polymerized under catalyst. The character is white to milky white powder; Odorless or slightly extra smelly, tasteless; It is moisture-inducing. Dissolved in water, ethanol, isopropyl alcohol, or trichloromethane, insoluble in acetone or ether.

use
Povidone K30 is generally used as a binder for tablets and granules, and the dosage is generally 3%-5%. Povidone K30 is soluble in organic solvents such as water, alcohol and isopropyl alcohol, so increasing its dosage does not delay the disintegration of tablets. For hydrophobic drugs, the aqueous solution of POvidone K30 is used as the adhesive, which is not only easy to be evenly wet, but also can make the surface of the hydrophobic drug become hydrophilic, which is conducive to the dissolution of the drug and the disintegration of the tablet. Povidone K30 is the adhesive for the preparation of effervescent tablets, and it is also suitable for heat-sensitive drugs. The adhesive effect will not change with time, and the hardness of the pressed tablet is high. The appearance is smooth and beautiful. The disintegration time is short and the dissolution rate is high.
Lay by
Shade, seal and store in a dry place.
Production method:
N-vinyl-2-pyrrolidone is polymerized and crosslinked in the presence of an alkaline catalyst or N, N ‘-divinylimidazole, and then water, 5% acetic acid and 50% ethanol are returned to the extract ≤50mg/kg (about 3 hours or more).
