  • 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.

  • Tunable sustained release of a sparingly soluble hydrophobic therapeutic agent from a hydrogel matrix
    Patent number: 9205047
    Abstract: The incorporation of polymeric excipients into an injectable hydrogel matrix, for example, methyl cellulose in the case of a hydrogel matrix comprising hyaluronan and methylcellulose (HAMC) has been found to increase the solubility of sparingly soluble hydrophobic drugs and tune their rate of release. The hydrogel matrix may also include other sparingly soluble hydrophobic food or cosmetic agents.
