Application

  • Thermo-responsive aqueous foams: Hydroxypropyl cellulose has been studied for its properties as a green polymer that can alter its solubility with temperature changes, making it suitable for responsive foam applications (Braunschweig, 2019).
  • Interaction mechanism in aqueous solutions: A study on the interaction between hydroxypropyl cellulose and water in solutions, focusing on the importance of polymer chain length in determining the physical properties of the solutions (Martin-Pastor and Stoyanov, 2020).
  • Corrosion inhibition: Hydroxypropyl cellulose has shown effectiveness as a corrosion inhibitor for aluminium in acidic environments, highlighting its potential in material science and engineering applications (Nwanonenyi et al., 2019).
  • Orally disintegrating films: This application involves the formulation design of hydroxypropyl cellulose films, aiming to enhance the delivery and dissolution profile of pharmaceuticals, making it significant in drug delivery and pharmaceutical sciences (Takeuchi et al., 2018).

Living organisms secrete minerals composed of peptides and proteins, resulting in "mesocrystals" of three-dimensional-assembled composite structures. Recently, this biomimetic polymer-directed crystallization technique has been widely applied to inorganic materials, although it has seldom been used with drugs. In this study

The present study was undertaken to develop a solid self-emulsifying drug delivery system of coenzyme Q(10) (CoQ(10)/s-SEDDS) with high photostability and oral bioavailability. The CoQ(10)/s-SEDDS was prepared by spray-drying an emulsion preconcentrate containing CoQ(10), medium-chain triglyceride, sucrose ester of fatty
