Used in conjunction with carbon black to form a conductive composite. 1 Polymer nanospheres of poly(ethylene glycol) were used for drug delivery
Applications:
Polyethylene glycol 400 is suited to prepare for the soft capsule most. The polyethylene glycol 400 is a liquid and has a broad compatibility with various solvents, so it is a good solvent and solubilizer and is widely used in liquid preparations, such as the oral solution, eye drops and so on.
When the vegetable oil is not suitable for a co-active ingredient carrier material, the polyethylene glycol is the preferred substitute material because the polyethylene glycol is stable and non-perishable. Besides, the injections containing polyethylene glycol are very safe and stable as long as it has been heated to 150 degrees Celsius. In addition, it can blend with PEG with high molecular weight and the mixture has a good solubility and drug compatibility.
