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.
