Product description:
Like all homopolymer series products, because povidone k30 contains hydrophilic and lipophilic groups in its molecular structure, it can interact with many solvents, making it soluble in water, and soluble in a variety of alcohols and carboxylic acids. Amine and halogenated in organic solvents. The solubility is only limited by its own viscosity.

Application:
Povidone k30 is widly used in pharmaceutical field, and it is one of medicinal synthetic excipients, mainly used as a binder for tablets and granules.
Physical properties:
1.Solubility and solution characteristics:
Povidone k30 contains hydrophilic and lipophilic groups in its molecular structure, it can interact with many solvents, making it soluble in water, and soluble in a variety of alcohols and carboxylic acids，Amines and halogenated hydrogens and other organic solutions. The solubility is only limited by its own viscosity.
2.Surface activity:
The molecule of PVPK30 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.
