詳細

Hydroxypropyl cellulose (HPC) is a nonionic derivativeof cellulose. It is a thermosensitive, biodegradable polymer with low criticalsolution temperature.

アプリケーション

Hydroxypropyl cellulose can be used to prepare composite nanospheres for drug delivery systems. Hydroxypropyl methacrylate/hydroxy cellulose graft copolymers can be used as matrices for controlled-release tablets. It can also be used as an electrolyte additive to prepare gel polymerelectrolytes for dye-sensitized solar cells.

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
