  • Antibacterial surfactant/microgel formulations, methods of making and methods of using the same
    Patent number: 9560849
    Abstract: In a first broad aspect, described herein is an antimicrobial formulation comprised of: at least one nonionic surfactant capable of providing colloidal stability to the formulation, and at least one quaternized polymeric microgel capable of being dispersed in the nonionic surfactant. The quaternized polymeric microgel is comprised of one or more of: chitosan oligomers or chitosan polymers. Further, the antimicrobial formulation is essentially free of cationic surfactants.
