Glycerin refers to a special medicine made by dissolving drugs in glycerin Solution for external use. It is viscous, antiseptic and hygroscopic, and is often used in the mouth, nasal cavity, ear cavity and throat.
According to the supply of glycerol: Glycerol (also known as glycerin) is an organic substance that is colorless, odorless, sweet, and appears as a clear viscous liquid. 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
3. Iodine glycerin: commonly used clinically as a disinfectant Antiseptic, can be used for oral mucosal ulcers, gingivitis and pericoronitis.
Advantages of glycerin:
1. Safety: Glycerin is harmless to the human body. It can effectively and safely make close contact with human skin. Gentle and effective on the skin, glycerin can be used for treatment or maintenance.
2. Good water and oil solubility; strong tolerance: It is a good auxiliary material in itself, and it can be added with various substances to make products with various functions.
3. Viscosity: It can reduce the settling speed of drug particles and is a good dispersing medium. This property makes the glycerin agent very convenient to use, and it can effectively spread the glycerin agent evenly on the skin.

5. Anti-corrosion: The physical properties are very stable, not easy to deteriorate, and the effect can be preserved for a long time. Glycerin has a long service life and is very practical whether it is used to make medicines or skin care products.
