Polyethylene glycol (PEG;PEG 600 /ˌpɒliˈɛθəlˌiːn ˈɡlaɪˌkɒl, -ˌkɔːl/) is a polyether compound with many applications, from industrial manufacturing to medicine. PEG is also known as polyethylene oxide (PEO) or polyoxyethylene (POE), depending on its molecular weight. The structure of PEG 600 is commonly expressed as H-(O-CH2-CH2)n-OH.

Medical uses
Main article: Macrogol
PEG 600 is the basis of a number of laxatives.[3] Whole bowel irrigation with polyethylene glycol and added electrolytes is used for bowel preparation before surgery or colonoscopy. PEG 600 is also used as an excipient in many pharmaceutical products. When attached to various protein medications, polyethylene glycol allows a slowed clearance of the carried protein from the blood.[4] The possibility that PEG 600 could be used to fuse nerve cells is being explored by researchers studying spinal cord injury.[3] Chemical uses The remains of the 16th century carrack Mary Rose undergoing conservation treatment with PEG 600 in the 1980s Terra cotta warrior, showing traces of original color Because PEG 600 is a hydrophilic molecule, it has been used to passivate microscope glass slides for avoiding non-specific sticking of proteins in single-molecule fluorescence studies.[5] Polyethylene glycol has a low toxicity and is used in a variety of products.[6] The polymer is used as a lubricating coating for various surfaces in aqueous and non-aqueous environments.[7] Since PEG is a flexible, water-soluble polymer, it can be used to create very high osmotic pressures (on the order of tens of atmospheres). It also is unlikely to have specific interactions with biological chemicals. These properties make PEG 600 one of the most useful molecules for applying osmotic pressure in biochemistry and biomembranes experiments, in particular when using the osmotic stress technique. Polyethylene glycol is also commonly used as a polar stationary phase for gas chromatography, as well as a heat transfer fluid in electronic testers. PEG 600 has also been used to preserve objects that have been salvaged from underwater, as was the case with the warship Vasa in Stockholm,[8] and similar cases. It replaces water in wooden objects, making the wood dimensionally stable and preventing warping or shrinking of the wood when it dries.[3] In addition, PEG 600 is used when working with green wood as a stabilizer, and to prevent shrinkage.[9] PEG has been used to preserve the painted colors on Terracotta Warriors unearthed at a UNESCO World Heritage site in China.[10] These painted artifacts were created during the Qin Shi Huang Di dynasty (first emperor of China). Within 15 seconds of the terra-cotta pieces being unearthed during excavations, the lacquer beneath the paint begins to curl after being exposed to the dry Xian air. The paint would subsequently flake off in about four minutes. The German Bavarian State Conservation Office developed a PEG 600 preservative that when immediately applied to unearthed artifacts has aided in preserving the colors painted on the pieces of clay soldiers.[11] PEG 600 is often used (as an internal calibration compound) in mass spectrometry experiments, with its characteristic fragmentation pattern allowing accurate and reproducible tuning. PEG 600 derivatives, such as narrow range ethoxylates, are used as surfactants. PEG 600 is a polyol and can be reacted with an isocyanate to make polyurethane. PEG 600 has been used as the hydrophilic block of amphiphilic block copolymers used to create some polymersomes.[12] Biological uses PEG 600 is commonly used as a crowding agent in in vitro assays to mimic highly crowded cellular conditions.[5] PEG 600 is commonly used as a precipitant for plasmid DNA isolation and protein crystallization. X-ray diffraction of protein crystals can reveal the atomic structure of the proteins. PEG is used to fuse two different types of cells, most often B-cells and myelomas in order to create hybridomas. César Milstein and Georges J. F. Köhler originated this technique, which they used for antibody production, winning a Nobel Prize in Physiology or Medicine in 1984.[3] Polymer segments derived from PEG polyols impart flexibility to polyurethanes for applications such as elastomeric fibers (spandex) and foam cushions. In microbiology, PEG 600 precipitation is used to concentrate viruses. PEG is also used to induce complete fusion (mixing of both inner and outer leaflets) in liposomes reconstituted in vitro. Gene therapy vectors (such as viruses) can be PEG-coated to shield them from inactivation by the immune system and to de-target them from organs where they may build up and have a toxic effect.[13] The size of the PEG polymer has been shown to be important, with larger polymers achieving the best immune protection. PEG is a component of stable nucleic acid lipid particles (SNALPs) used to package siRNA for use in vivo.[14][15] In blood banking, PEG is used as a potentiator to enhance detection of antigens and antibodies.[3][16] When working with phenol in a laboratory situation, PEG 300 can be used on phenol skin burns to deactivate any residual phenol. In biophysics, polyethylene glycols are the molecules of choice for the functioning ion channels diameter studies, because in aqueous solutions they have a spherical shape and can block ion channel conductance.[17][18]

 

 

 

Commercial uses
PEG 600 is the basis of many skin creams (as cetomacrogol) and personal lubricants (frequently combined with glycerin). PEG 600 is used in a number of toothpastes[3] as a dispersant. In this application, it binds water and helps keep xanthan gum uniformly distributed throughout the toothpaste. PEG 600 is also under investigation for use in body armor, and in tattoos to monitor diabetes.[19][20] In low-molecular-weight formulations (e.g. PEG 400), it is used in Hewlett-Packard designjet printers as an ink solvent and lubricant for the print heads. PEG 600 is also used as an anti-foaming agent in food and drinks[21] - its INS number is 1521[22] or E1521 in the EU.[23] Industrial uses A nitrate ester-plasticized polyethylene glycol (NEPE-75) is used in Trident II submarine-launched ballistic missile solid rocket fuel.[24] Dimethyl ethers of PEG are the key ingredient of Selexol, a solvent used by coal-burning, integrated gasification combined cycle (IGCC) power plants to remove carbon dioxide and hydrogen sulfide from the gas waste stream. PEG 600 has been used as the gate insulator in an electric double-layer transistor to induce superconductivity in an insulator.[25] PEG 600 is also used as a polymer host for solid polymer electrolytes. Although not yet in commercial production, many groups around the globe are engaged in research on solid polymer electrolytes involving PEG 600, with the aim of improving their properties, and in permitting their use in batteries, electro-chromic display systems, and other products in the future. PEG 600 is injected into industrial processes to reduce foaming in separation equipment. PEG 600 is used as a binder in the preparation of technical ceramics.[26] Health effects PEG 600 is generally considered biologically inert and safe. However, studies of clinical safety are generally based on adults, not children. The FDA has been asked to investigate the possible effects of PEG in laxatives for children.[27]

 

A minority of people are allergic to it. Allergy to PEG is usually discovered after a person has been diagnosed with an allergy to an increasing number of seemingly unrelated products, including processed foods, cosmetics, drugs, and other substances that contain PEG or were manufactured with PEG 600.[28] When PEG is chemically attached to therapeutic molecules (such as protein drugs or nanoparticles), it can sometimes be antigenic, stimulating an anti-PEG antibody response in some patients. This effect has only been shown for a few of the many available PEGylated therapeutics, but it has significant effects on clinical outcomes of affected patients.[29] Other than these few instances where patients have anti-PEG immune responses, it is generally considered to be a safe component of drug formulations. Available forms and nomenclature PEG, PEO, and POE refer to an oligomer or polymer of ethylene oxide. The three names are chemically synonymous, but historically PEG is preferred in the biomedical field, whereas PEO is more prevalent in the field of polymer chemistry. Because different applications require different polymer chain lengths, PEG 600 has tended to refer to oligomers and polymers with a molecular mass below 20,000 g/mol, PEO to polymers with a molecular mass above 20,000 g/mol, and POE to a polymer of any molecular mass.[30] PEG 600 s are prepared by polymerization of ethylene oxide and are commercially available over a wide range of molecular weights from 300 g/mol to 10,000,000 g/mol.[31] PEG 600 and PEO are liquids or low-melting solids, depending on their molecular weights. While PEG 600 and PEO with different molecular weights find use in different applications, and have different physical properties (e.g. viscosity) due to chain length effects, their chemical properties are nearly identical. Different forms of PEG are also available, depending on the initiator used for the polymerization process - the most common initiator is a monofunctional methyl ether PEG 600, or methoxypoly(ethylene glycol), abbreviated mPEG. Lower-molecular-weight PEGs are also available as purer oligomers, referred to as monodisperse, uniform, or discrete. Very high purity PEG 600 has recently been shown to be crystalline, allowing determination of a crystal structure by x-ray diffraction.[31] Since purification and separation of pure oligomers is difficult, the price for this type of quality is often 10-1000 fold that of polydisperse PEG 600 PEGs are also available with different geometries. Branched PEGs have three to ten PEG 600 chains emanating from a central core group. Star PEGs have 10 to 100 PEG chains emanating from a central core group. Comb PEGs have multiple PEG 600 chains normally grafted onto a polymer backbone. The numbers that are often included in the names of PEGs indicate their average molecular weights (e.g. a PEG with n = 9 would have an average molecular weight of approximately 400 daltons, and would be labeled PEG 400.) Most PEGs include molecules with a distribution of molecular weights (i.e. they are polydisperse). The size distribution can be characterized statistically by its weight average molecular weight (Mw) and its number average molecular weight (Mn), the ratio of which is called the polydispersity index (Mw/Mn). Mw and Mn can be measured by mass spectrometry.

 

PEGylation is the act of covalently coupling a PEG structure to another larger molecule, for example, a therapeutic protein, which is then referred to as a PEGylated protein. PEGylated interferon alfa-2a or -2b are commonly used injectable treatments for hepatitis C infection. PEG is soluble in water, methanol, ethanol, acetonitrile, benzene, and dichloromethane, and is insoluble in diethyl ether and hexane. It is coupled to hydrophobic molecules to produce non-ionic surfactants.[32] PEGs potentially contain toxic impurities, such as ethylene oxide and 1,4-dioxane.[33] Ethylene Glycol and its ethers are nephrotoxic if applied to damaged skin.[34] Polyethylene oxide (PEO, Mw 4 kDa) nanometric crystallites (4 nm) Polyethylene glycol (PEG) and related polymers (PEG phospholipid constructs) are often sonicated when used in biomedical applications. However, as reported by Murali et al., PEG is very sensitive to sonolytic degradation and PEG degradation products can be toxic to mammalian cells. It is, thus, imperative to assess potential PEG degradation to ensure that the final material does not contain undocumented contaminants that can introduce artifacts into experimental results.[35] PEGs and methoxypolyethylene glycols are manufactured by Dow Chemical under the tradename Carbowax for industrial use, and Carbowax Sentry for food and pharmaceutical use. They vary in consistency from liquid to solid, depending on the molecular weight, as indicated by a number following the name. They are used commercially in numerous applications, including as surfactants, in foods, in cosmetics, in pharmaceutics, in biomedicine, as dispersing agents, as solvents, in ointments, in suppository bases, as tablet excipients, and as laxatives. Some specific groups are lauromacrogols, nonoxynols, octoxynols, and poloxamers Macrogol, used as a laxative, is a form of polyethylene glycol. The name may be followed by a number which represents the average molecular weight (e.g. macrogol 3350, macrogol 4000 or macrogol 6000). Production Polyethylene glycol 400, pharmaceutical quality Polyethylene glycol 4000, pharmaceutical quality production of polyethylene glycol was first reported in 1859. Both A. V. Lourenço and Charles Adolphe Wurtz independently isolated products that were polyethylene glycols.[36] Polyethylene glycol is produced by the interaction of ethylene oxide with water, PEG 600, ethylene glycol, or ethylene glycol oligomers.[37] The reaction is catalyzed by acidic or basic catalysts. Ethylene glycol and its oligomers are preferable as a starting material instead of water, because they allow the creation of polymers with a low polydispersity (narrow molecular weight distribution). Polymer chain length depends on the ratio of reactants.

Depending on the catalyst type, the mechanism of polymerization can be cationic or anionic. The anionic mechanism is preferable because it allows one to obtain PEG with a low polydispersity. Polymerization of ethylene oxide is an exothermic process. Overheating or contaminating ethylene oxide with catalysts such as alkalis or metal oxides can lead to runaway polymerization, which can end in an explosion after a few hours. Polyethylene oxide, or high-molecular weight polyethylene glycol, is synthesized by suspension polymerization. It is necessary to hold the growing polymer chain in solution in the course of the polycondensation process. The reaction is catalyzed by magnesium-, aluminium-, or calcium-organoelement compounds. To prevent coagulation of polymer chains from solution, chelating additives such as dimethylglyoxime are used. Alkaline catalysts such as sodium hydroxide (NaOH), potassium hydroxide (KOH), or sodium carbonate (Na2CO3) are used to prepare low-molecular-weight polyethylene glycol.

The collected ice was then kept in well insulated warehouse to satisfy the needs for food conservation, air conditioning through the year. The air conditioning of Hungarian Parliament Building in Budapest is still done by ice harvested from Lake Balaton in the winter [1]. In order to condition the indoors air via changing the material phase, phase change material (PCM) can be embedded in a heat exchanger. During the night PEG 600, PCM solidifies and the energy can be released (discharge cycle) and subsequently during the hot day, via a move through the heat exchanger, air is cooled and PCM melts (charge cycle). Medved and Arkar [2]-[5] used a cylindrical LHTES filled with spheres of encapsulated RT20 paraffin. They concluded that the ratio of the volumetric air flow to mass of the PCM has more influence upon the results than each individual parameter [2]. They also concluded that the greatest potential for free cooling exists in the areas with a higher temperature difference between the day and the night, i.e. variation of diurnal temperature is the major factor. Moreover, they showed that the most suitable PCM for each area is the one with a melting point of 2  C higher than the average diurnal temperature [3]. In order to model the heat transfer in the LHTES under unsteady-state conditions, they used an adapted 2D continuous-solid-phase packed-bed model. The major assumption of this model is that the spheres behave as a continuous medium and not as a medium comprised of independent particles. Moreover fluid phase thermal dispersion, this model can consider the solid-phase heat conduction [2]. Vakilaltojjar and Saman [6] integrated a flat slab phase change thermal storage unit (PCTSU) employing two PCMs (calcium chloride hexahydrate and Potassium fluoride tetrahydrate) in different sections into conventional air conditioning. They proposed 3 models with different assumptions. The results of their investigation showed that decreasing the gaps between flat slabs enhances the efficiency. In the present research work a one-dimensional model including axial conduction for a LHTES containing flat slabs of PCM has been presented. The modeling data have been validated by the experimental results. Our goal is to investigate the accuracy of the proposed model for describing the LHTES and also to investigate the dependency of LHTES efficiency on the operational parameters i.e. velocity and temperature of the heat transfer fluid. Poly Ethylene Glycol 600 (PEG 600), a product of Fluka Corporation, and Poly Ethylene Glycol 1000 (PEG 1000) have been used as PCM. In order to find out the temperature span for the phase change of PEG 600 and PEG 1000, DSC analysis was done by "Netzsch DSC 200 F3". Results of this analysis are shown in Fig. 1 and Fig. 2. Other properties of PEG 600 and PEG 1000 are listed in Table 1. In this model the major assumption is that all the existing PCM in each control volume behave simultaneously. The mathematical model is based on the following assumptions: 1- Axial conduction in the air is neglected in the direction of the flow. For justifying this assumption Peclet number can be used [8]: P e > 100 axial conduction in the air can be neglected in the flow direction P e < 100 axial conduction in the air can NOT be neglected in the flow ...

High-performance liquid chromatographic determination of PEG 600 in human urine. Kinahan IM1, Smyth MR. Author information 1 School of Chemical Sciences, Dublin City University, Ireland. Abstract Polyethylene glycols (PEGs) are non-ionic, water-soluble synthetic polymers which have been widely used for many applications. Since they are of very low toxicity and are readily excreted in urine, PEGs in the molecular weight range 400-6000 have been used extensively in the study of intestinal physiology in man. A high-performance liquid chromatographic (HPLC) method has been developed for the determination of PEG 600 in human urine, which includes a pre-column derivatisation step. The dibenzoate derivatives of PEG 600 can be quantitatively prepared, and this, coupled with ultraviolet detection at 230 nm, has greatly improved the limit of detection for the determination of PEGs by HPLC. A suitable extraction procedure has also been developed which enabled PEG levels in urine to be monitored with much greater sensitivity than any previously reported method.

Characterization of cellulose triacetate membranes, produced from sugarcane bagasse, using PEG 600 as additive

Authors Authors and affiliations Daniel Alves CerqueiraGuimes Rodrigues FilhoEmail authorRosana Maria Nascimento de AssuncãoCarla da Silva MeirelesLeandra Cardoso ToledoMara ZeniKátia MelloJocelei Duarte 1. 2. First Online: 24 October 2007 Cellulose Acetate (CA) produced from sugarcane bagasse cellulose was used to produce membranes, using poly(ethylene glycol) (PEG 600) as additive. Results showed that PEG 600 was washed out the membranes during the preparation step. Thermal Analysis showed that the temperature of degradation of the membranes increased in 10 °C when PEG 600 was added to the composition, but did not change as more PEG 600 was added in the composition. On the other hand, the crystalline content (%C) of the membranes increased as PEG 600 was added. The addition of PEG 600 also increased the resistance of the membranes to pressure and the pure water flux rate, but membranes produced with PEG 600 content lower than 5% did not present water flux. PEG 600 also increased the coefficient of ion diffusion of the membranes.

Abstract:
The building sector is one of the sectors where energy consumption has been expanding consistently to achieve 20-40% of the aggregate energy use in most countries. Thermal energy storage (TES) with phase change materials (PCM) is valuable technique for enhancing energy proficiency of a building by lessening the mismatch amongst supply and demand of heat or cold. This paper aims to investigate thermal comfort and energy saving in buildings by incorporating polyethylene glycol (PEG) 600 as phase change material with concrete. A concrete PCM system which is located in Khartoum, Sudan was used to study the thermal behavior of a building in response to outdoor environmental exposure. The concrete PCM ceiling system is consisted of two models; one with PCM and the other without PCM. The experimental analysis was done with and without present of fan in the concrete model with PCM. The results showed that the model with PCM could reduce the peak temperature with and without using fan by 4 °C and 1 °C respectively. The results additionally demonstrated that PCM could improve the storage of thermal mass of concrete about 6 times. The heat capacity and high density of concrete integrated with latent heat storage of PCM provides an energy saving concepts for sustainable built environment.

I. Introduction
Energy has constantly been the predominant main PEG 600 impetus for the financial advancement of humanity. During last decades, the energy systems around the world are abundantly depended upon non-sustainaule energy sources (i.e., petroleum, natural gas, and coal) with all the consequent impediments such as fossil fIJel energy reliance and ecological pollution [1]. Amid several decades, developed and developing countries have utilized fossil energy seriously for development purposes in almost all economic segments such as manufacturing industry, residents, transport, and agriculture. This prompted imperative carbon dioxide (CO2) emissions in almost all areas of the world [2]. The building sector is one of the sectors where energy consumption has been expanding consistently to achieve 20- 40% of the aggregate energy use in most countries. PEG 600 As request in thermal comfort of structures increases progressively, the energy consumption is correspondingly expanding. The most amount of energy consumption in buildings PEG 600 sector is associated with ventilation, heating and cooling systems [3]. The need of enhancing the energy efficiency of the constructed condition brought about the improvement of different techniques of better utilization of energy in buildings [4]. One of the preeminent worries ofuse of air conditioning systems, which have generally been utilized in residential and industrial sectors, is electrical energy usage for gas compression which is practical as well as prompts more ozone harming gases, shortage of fossil fuels in the close feature, daily ascend in fuel costs and environmental difficulties, which are the primary motivators to discover ways for utilizing energy more adequately particularly in residential sectors. Thermal energy storage (TES) is valuaule innovation for enhancing energy proficiency of a building by lessening the mismatch amongst supply and demand ofheat or cold.
