Polyvinylpyrrolidone pvp k30 is widly used in pharmaceutical field , and it is one of medicinal synthetic excipients, it can be used as a delaying agent, lubricant and coating film forming agent for eye drops. Povidone has a wide range of applications in the field of medicine, and is one of the three major new pharmaceutical excipients advocated by the world. The most widely used are adhesives for tablets and granules.

Povidone can also be combined with iodine to synthesize povidone-iodine (PVP-I) disinfectant and fungicide. In contact lenses, PVP is used as an ingredient in contact lenses to increase their hydrophilicity. PVP can also be used as a cryopreservation agent in medicine.

1.CharacteristicsFilm-forming and hygroscopicity:

Polyvinylpyrrolidone pvp k30 has strong hygroscopicity, its moisture absorption capacity is weaker than carboxymethyl cellulose (CMC), but stronger than polyvinyl alcohol (PVA). Once PVPK30 absorbs moisture, it will show a certain degree of adhesion. The equilibrium moisture content of PVPK30 is about 1/3 of the relative humidity.

2.Surface activity:

The molecule of Polyvinylpyrrolidone pvp k30 has a butyrolactam structure, which contains a large polar lactam group with a dipole moment of 40, which has the ability to be hydrophilic and polar group. In addition, there are non-polar methylene (-CH2-) and methine (CH=) groups on the molecular ring and in the long chain, making it lipophilic.
