The present disclosure discloses a rosin-based small molecular weight hydrogelator and an application thereof, and belongs to the fields of supramolecular chemistry, surfactant science and chemical utilization of rosin. The rosin-based small molecular hydrogel of the present disclosure can gel water at a very low concentration, and the critical gelling concentration is only 0.176 wt %. On average, each gelling agent molecule can hold 13,889 water molecules, which exhibits extremely high gel efficiency and the formed small molecular hydrogel also exhibits extremely high stability. This small molecule hydrogel is derived from the natural product rosin and has a mild nature. It can be used in the fields of drug sustained-release, tissue engineering, daily chemicals, medicine and so on. At the same time, the rosin-based small molecular hydrogel 6-dehydroabietylamide amine oxide in the present disclosure can form a stable gel emulsion for most oils, and can be used in many fields such as food, medicine, daily chemicals, tissue engineering, environmental protection, and water pollution control.

The present invention relates to a dispersant derived from an alcohol terminated polymer and via an anhydride intermediate. The anhydride functionalized polyester is then reacted with a multi-amine species forming amide and salt bonds.

Polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions are useful in dispersing various compounds in a carrier liquid. The polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions employ polymers having both hydrophilic domains and hydrophobic domains so that the compositions can disperse particles such as polymer particles or droplets in a continuous phase as well as provide stable dispersions that have not been provided before. The antimicrobial properties of the compositions provide much-needed capabilities of fighting infectious agents such as bacteria and viruses in a wide spectrum of products such as paint, adhesives, and coatings. Methods of using these compositions as well as methods of making products using the compositions are disclosed.

Stabilized foams are provided, adapted in particular for subterranean applications in hydrocarbon recovery operations. The foams are stabilized with surfactant-decorated nanoparticles, and the decoration of the nanoparticles with surfactant may be titrated to tune the stabilization of the foam.

The present invention relates to a dispersant derived from anhydride functionalized polyester derived from carboxylic acid functionalized polyester. The anhydride functionalized polyester is then reacted with a multi-amine species forming amide and salt bonds. The technology allows lower reaction temperatures when the multi-amine species is present. The lower reaction temperature allows the use of a broader selection of polyester repeat units.
