It is miscible with water, alcohols, amines and phenols in any proportion, and the aqueous solution is neutral. Glycerin is a polyol moisturizer. The hydroxyl groups in the molecular structure can form hydrogen bonds with water molecules, which plays a good role in absorbing and locking water. Glycerin has a wide range of uses. Currently, it has more than 1,700 uses. It is used in both food and industry. Glycerol can generally be divided into four grades: industrial grade, cosmetic grade, food grade, and pharmaceutical grade. Because glycerin is viscous, antiseptic, and hygroscopic, it has a moisturizing effect on the skin and mucous membranes. It can retain the drug in the affected area and prolong the local efficacy of the drug. It is often used for otolaryngology diseases. Glycerol has greater solubility in boric acid, tannic acid, phenol and iodine, and has a certain easing effect on some irritating drugs, so it can be used on mucous membranes. Glycerin is highly hygroscopic and should be stored in an airtight container.

Commonly used glycerin agents are:

1. Boric acid glycerin: its main components are boric acid and glycerin Glyceryl borate produced by chemical reaction can be used for acute and chronic otitis media.

2. Phenol glycerin: commonly used clinically as a disinfectant and antiseptic, and can be used for tonsillitis, ulcerative stomatitis and non-perforated otitis externa
