Benzyl 4-hydroxybenzoate is a prominent material that can be used as an excipient, such as a bacteriostatic agent or preservative. Pharmaceutical excipients, also known as pharmaceutical auxiliaries, are chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. They generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility, and processability of these preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs.
