  • Rosin-based small molecular weight hydrogelator and its application
    Patent number: 11352317
    Abstract: 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.
