CAS：56-81-5

Function：

- Solvent and carrier: Glycerol has good solubility and can dissolve many drug components, making it a commonly used solvent in veterinary drug production. It can uniformly disperse some poorly soluble drugs in preparations, such as certain fat-soluble vitamins and antibiotics, helping to stabilize the drugs and enhance their absorption. Meanwhile, glycerol can also serve as a carrier for drugs, delivering them to specific sites in animals to improve the bioavailability of the drugs.

- Humectant: In some external veterinary preparations such as ointments and creams, glycerol is often used as a humectant. It can absorb moisture from the air, maintain the wet state of the preparations, prevent them from drying and cracking, and help retain moisture in the skin or mucous membranes to promote better penetration and efficacy of the drugs.

- Protective agent: Glycerol can form a protective film on the surface of animal skin and mucous membranes to reduce damage to tissues from external stimuli. For example, preparations containing glycerol can protect wounds, prevent infection, and facilitate wound healing in conditions such as skin inflammation and ulcers. In addition, in some biological products, glycerol can act as a protective agent to stabilize bioactive substances and prevent them from losing activity during storage and transportation.

- Laxative: Oral glycerol can be used as a laxative. It increases water in the intestines, softens stools, and promotes intestinal peristalsis, thereby relieving constipation in animals. It is particularly suitable for constipation caused by dry intestines and hard stools.
