Excipient (pharmacologically inactive substance)
What is it?
Wax is a sticky yellowish moldable substance secreted by honeybees as the material of honeycomb; also known as beeswax. Most waxes used in the pharmaceutical industry are used for tablet coatings and binding. Wax is also used in preparing ointments, cerates, plasters, and suppositories. The main types of wax include yellow wax (beeswax), white wax and wax absolute.
