| Bioactivity | Hydroxypropyl Cellulose is somewhat amphiphilic in character and is a surfactant. Hydroxypropyl Cellulose can be used as a pharmaceutical excipient, such as coating agent, emulsifier, suspension, tablet, thickener, viscosifier. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs[1][2]. | ||||||||||||
