Polyaminopropyl biguanide
Based on 1 Customer Validation
Polyaminopropyl biguanide (PAPB) is a positively charged antimicrobial polymer and cosmetic preservative. Polyaminopropyl biguanide inhibits the growth and division of negatively charged microorganisms via charge-based adsorption. Polyaminopropyl biguanide exhibits broad-spectrum in vitro activity against foodborne microorganisms and postharvest fruit pathogens. Polyaminopropyl biguanide can be used in studies related to citrus postharvest diseases and foodborne bacterial infections.

Biological Activity
Polyaminopropyl biguanide (0.125-0.25%) significantly enhances the tensile strength and elongation at break of PEC/PVA composite films, with the 0.25% formulation exhibiting the highest tensile strength of up to 26.90 MPa[2].
Polyaminopropyl biguanide (0.125-1%) reduces the diffraction peak intensity of PEC/PVA composite films and improves their thermal stability in a concentration-dependent manner[2].
The polyaminopropyl biguanide/PEC/PVA composite films (0.125-1%) exhibit potent in vitro antibacterial activity, including 100% inhibition of Penicillium italicum at a polyaminopropyl biguanide concentration of 0.125%, and show stronger activity against Staphylococcus aureus than against Escherichia coli[2].
