PEG6000 is used as a pharmaceutical excipient, such as in ointment bases and lubricants. Pharmaceutical excipients, or adjuvants, are chemical substances used in the pharmaceutical process excluding active drug components. They generally refer to the inactive components in drug formulations that enhance the stability, solubility, and manufacturability of the drug. Excipients also impact the absorption, distribution, metabolism, and elimination (ADME) processes of combined medications.
