Product introduction:
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.
Polyethyleneglycol is a kind of high polymer, the chemical formula
isHO(CH2CH2O)NH, non-irritating, slightly bitter taste, with good
water solubility, and many organic components have good
compatibilityt has excellent lubricity. moisture retention.dispersion
and adhesion.

Polyethylene glycol is abbreviated as "PEG". A polymer compound formed by intermolecular dehydration condensation of ethylene glycol. The chemical formula is HOCH2(CH2OCH2)nCH2OH. where n is greater than 4. The average molecular weight is 200-7000. The numbers following commercial polyethylene glycols indicate average molecular weights. For example, polyethylene glycol-400 means that the average molecular weight of the commercial polyethylene glycol is about 400.
Colorless viscous liquid or white solid. Soluble in water and many organic solvents, easily soluble in aromatic hydrocarbons, slightly soluble in aliphatic hydrocarbons
Application:
Used as analytical reagents, also in the pharmaceutical industry;
For softeners, lubricants, etc.;
It is used as a matrix in medicine and cosmetics, and as a dispersant, lubricant, emulsifier, etc. in rubber, metal processing, pesticide and other industries;
Medium for organic synthesis, humectant for daily cosmetic industry, inorganic salt solubilizer, viscosity modifier, etc.;
Used in cosmetic, pharmaceutical, chemical fiber, rubber, paper, paint, electroplating, pesticide, metal processing and food processing industries
Polyethylene glycol with high relative molecular weight (Mr >2000) is suitable for lipsticks, deodorant sticks, soaps, shaving soaps, foundations and beauty cosmetics.
