1.PEG400 is suitable for soft capsules. Because PEG400 is liquid, it has a wide range of compatibility with various solvents, is a good solvent and solvent, widely used in oral liquid, eye drops and other liquid preparations. PEG is the material of choice when vegetable oil is not suitable as an active substance component carrier. This is mainly because PEG is stable and does not spoil easily. When an injection containing PEG is heated to 150 degrees Celsius, it is very safe and stable. In addition, it can also be mixed with polymer volume (PEG), its mixture is good solubility, good compatibility with drugs.

PEG1450, 3350 is suitable for cream, suppository and cream. PEG1450, 3350 because of its high water solubility, wide melting point range, used alone or mixed, can produce a long storage time, in line with the requirements of medicine and physical effects of melting point range. Suppositories using PEG matrix are less irritating than traditional oil matrix suppositories.

3. PEG4000, 6000, 8000 for tablets, capsules, film coats, dropping pills, suppositories, etc.

The polymer PEG(PEG4000.PEG6000.PEG8000) is useful as a binder in the manufacture of tablets because of PEG's plasticity and its ability to release drugs during the manufacturing process. PEG can make the tablet surface glossy and not easy to damage. In addition, a small amount of PEG(PEG4000.PEG6000.PEG8000) with a high molecular weight can prevent the bonding between the icing tablet and the bottle.

4. Polyethylene glycol is mainly used in cell fusion technology.

Polyethylene glycol (PEG) molecules can alter the biofilm structure of various cells, evacuating and reorganizing lipid molecules in the plasma membrane at the point of contact between two cells. Due to the mutual affinity and surface tension of the bilayer plasma membrane at the junction of two cells, the cells fuse to form hybrid cells. Some special hybrid plants can be obtained by culture of hybrid cells (cytoplasmic hybrids).
