General description

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

Application

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 aim of this study was to determine whether hydroxypropylcellulose (HPC) coating of polyethylene terephthalate (PET) artificial ligaments enhances graft osseointegration in the bone tunnel. Thirty New Zealand white rabbits underwent artificial ligament graft transplantation in the bilateral proximal tibia

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
