Jellies are transparent or translucent nongreasy, semisolid preparation meant for external application to the mucus membrane. They are prepared from natural gums, such as tragacanth, pectin, sodium alginates, or from semisynthetic derivatives such as methyl cellulose and sodium carboxymethyl cellulose. There are three types of jellies, namely medicated jellies containing water soluble drugs, lubricating jellies, and miscellaneous jellies. Jellies are stored in well-filled and well-closed containers to minimize the evaporation of water and in a cool place to prevent drying out. Sterile jellies such as catheter lubricants are packed in collapsible tubes.
