Chemical Structure
Basic Info
Polyethylene Glycol ， Also referred to as polyethylene oxide or polyethylene oxide (POE), it refers to oligomers or polymers of ethylene oxide. Depending on the molecular weight, Polyethylene Glycol can be a fluid or a low melting factor solid. As a result of the influence of chain size, polyethylene glycol with different molecular weights commonly has different physical homes and applications, yet a lot of its chemical properties are similar. Those with a loved one molecular weight between 700 and 900 are semi-solid, while those with a relative molecular weight of 1000 or more are light white waxy solids, flocculent paraffin wax, or mobile powders.
Polyethylene glycol, a polymer compound, is abbreviated as “PEG”. Ethylene glycol is a high molecular weight compound developed by dehydration and condensation between molecules. Chemical formula HOCH2 (CH2OCH2) nCH2OH. Among them, n major chemical publications are released in 4. The typical molecular weight varieties from 200 to 7000. The number after polyethylene glycol represents the typical molecular weight of the item. For example, polyethylene glycol-400 shows that the average molecular weight of polyethylene glycol in this product is about 400.
Polyethylene Glycol is a colorless thick fluid or white strong. Low toxicity! Soluble in water and many organic solvents, easily soluble in fragrant hydrocarbons, slightly soluble in fatty hydrocarbons. Long term non hydrolysis, thermally secure, and non reactive with lots of chemical reagents. Some steel salts can dissolve in polyethylene glycol at around 100 ℃ and stay stable at space temperature. These steel salts consist of chlorides of calcium, cobalt, copper, iron, magnesium, manganese, tin, and zinc, potassium iodide, and ethylmercury. It can be made use of as a plasticizer, softener, moistening representative, lubricant, solvent, adhesive, and can likewise be created as a scent and made use of as a pharmaceutical formulation.
The Polyethylene Glycol series items are non-toxic, non irritating, slightly bitter in taste, and have good water solubility. They also have great compatibility with lots of organic elements.
The chemical buildings vary depending on the loved one molecular weight, ranging from anemic and odor-free viscous fluids to ceraceous solids. Those with a molecular weight of 200-600 are fluids at room temperature level, while those with a molecular weight above 600 progressively ended up being semi-solid. The properties additionally differ with the average molecular weight. Polyethylene Glycol varies from a colorless, odorless thick fluid to a waxy solid. As the molecular weight boosts, its moisture absorption ability reduces as necessary. This product is soluble in water, ethanol, and lots of various other natural solvents. Reduced vapor pressure, secure to warmth, acid, and antacids. Not effective with lots of chemicals. Has good moisture absorption, lubricity, and bond. Non toxic and non bothersome. The ordinary molecular weight is 300, n= 5 ～ 5.75 ， Melting factor -15 ~ 8 ℃, relative thickness 1.124 ~ 1.130. The average molecular chemistry book amount is 600, n= 12 ～ 13 ， Melting factor 20-25 ℃, flash factor 246 ℃, relative density 1.13 (20 ℃). The typical molecular weight is 4000, n= 70 ～ 85 ， Melting factor 53-56 ℃. Under regular problems, polyethylene glycol is extremely secure, but it can respond with oxygen in the air at temperatures of 120 ℃ or greater. In an inert atmosphere (such as nitrogen and co2), it does not alter even when heated up to 200-240 ℃, yet undergoes thermal splitting when the temperature level increases to 300 ℃. Including anti-oxidants, such as phenothiazine with a mass fraction of 0.25% to 0.5%, can enhance its chemical stability. Any decomposition items of it are unpredictable and do not create hard shells or sticky debris. Polyethylene Glycol
Polyethylene Glycol series
PEG400 is a liquid that is most suitable for making soft pills because of its stability and resistance to putridity. It is extensively used in fluid solutions such as dental fluids and is a superb solvent and thickener. PEG4000, PEG6000, PEG8000 can be made use of to make tablet computers, tablets, suppositories, and movie covers. During the manufacturing process, PEG can enhance the medication release capability of tablet computers and has good plasticity, making the surface of the tablets glossy and smooth, not easily damaged. Polyethylene Glycol can additionally protect against bond between sugar coated tablets.

Product Packaging
The major uses Polyethylene Glycol
Polyethylene Glycol has superb lubricity, moisturization, and dispersibility, and can be made use of as a softener and antistatic agent. It has a wide range of applications in sectors such as cosmetics, drugs, chemical fibers, rubber, plastics, papermaking, painting, electroplating, chemicals, metal processing, and food handling.
Polyethylene glycol can be used to change medication proteins, protect medicine particles, and lengthen their half-life. Polyethylene glycol molecules can modify the biofilm structure of different kinds of cells, causing the lipid molecules on the plasma membrane at the contact point between two cells to spread and recombine, leading to cell combination and the formation of hybrid cells, and obtaining some special hybrid plants.
Polyethylene glycol is additionally a preservative generally made use of for finishing sweet and delicious chocolate products. It can be made use of as a coating agent in food, along with a dispersant, binder, plasticizer, finishing representative, lubricating substance, carrier solvent, and flavoring representative.
Polyethylene Glycol can be utilized as a melting marketer
A superb chemical promoter for protoplast combination. It is a polymer of ethylene glycol with the molecular formula HOCH2 (CH2O · CH2) nCH2OH. Polyethylene Glycol is a white, a little yellowish waxy strong that is soluble in water and has a small odor. There are a collection of polymers with various relative molecular weights, and those with a relative molecular weight between 200 and 6000 can be utilized as melting marketers, but those with a loved one molecular weight of 1000 are much better (in liquid form at this time). Polyethylene Glycol has solid water solubility. In liquid media, the ether bonds on its molecular surface lug weak unfavorable costs. With the engagement of Ca2+ ions, positively charged surface area healthy proteins or adversely charged glycoproteins can be attached via Ca2+ bridges, causing cell aggregation and blend. In 50% PEG, the loss of cost-free water can lead to cell dehydration, resulting in adjustments in plasma membrane framework and cell blend.
The advantages of making use of Polyethylene Glycol in cell combination are:
① Strong universality, ideal for numerous cells of pets, plants, and bacteria.
② It is less complicated to prepare and manage than Sendai infection and various other viruses.
③ Secure activity and very easy to utilize.
The downside of polyethylene glycol is that its efficient focus array is fairly slim (50% to 55%), yet it is extra toxic to cells right now.② The combination process of cells can not be observed under a microscopic lense.
③ The regularity of inducing crossbreed cells is fairly reduced (concerning 1 × 10-5). In addition to being used as a melting promoter, it can also be used to advertise yeast uptake of exogenous changed DNA, and can be made use of as a precipitant in clinical chemistry, along with a osmoprotectant for lotion and various other aqueous options or suspensions.
