Polyethylene glycol(PEG) is apolyethercompound with many applications, from industrial manufacturing tomedicine. PEG is also known aspolyethylene oxide(PEO) orpolyoxyethylene(POE), depending on itsmolecular weight. The structure of PEG is commonly expressed as H(OCH₂CH₂)_nOH

PEG is also used as anexcipientin many pharmaceutical products

The possibility that PEG could be used to fuse nerve cells is being explored by researchers studyingspinal cord injury.

• Because PEG ishydrophilicmolecule, it has been used to passivate microscope glass slides for avoiding non-specific sticking of proteins in single-molecule fluorescence studies.^[13]
• Polyethylene glycol has a low toxicity and is used in a variety of products.^[14]The polymer is used as a lubricating coating for various surfaces in aqueous and non-aqueous environments

riethylene glycol, TEG, ortriglycolis acolorlessodorlessviscousliquid with molecular formula HOCH₂CH₂OCH₂CH₂OCH₂CH₂OH. It is used as aplasticizerforvinyl polymers. It is also used in air sanitizer products, such as "Oust"^[1]or "Clean and Pure". When aerosolized it acts as adisinfectant.Glycolsare also used as liquiddesiccantsfor natural gas and inair conditioningsystems. It is an additive forhydraulic fluidsandbrake fluidsand is used as a base for "smoke machine" fluid in the entertainment industry.

Triethylene glycol is a member of a homologous series of dihydroxyalcohols. It is a colorless, odorless and stable liquid with highviscosityand a high boiling point. Apart from its use as a raw material in the manufacture and synthesis of other products,

2-Butoxyethanolis anorganic compoundwith thechemical formulaBuOC₂H₄OH (Bu = CH₃CH₂CH₂CH₂). This colorless liquid has a sweet, ether-like odor, as it derives from the family ofglycol ethers, and is a butyl ether ofethylene glycol. As a relatively nonvolatile, inexpensive solvent of low toxicity, it is used in many domestic and industrial products because of its properties as asurfactant.

2-Butoxyethanol is a glycol ether with modestsurfactantproperties (and it can be used as a mutual solvent). In use since the 1930s, glycol ethersare solvents that dissolve both water-soluble andhydrophobicsubstances. Glycol ethers consist of two components, analcoholandether. According to the nature of alcohol, molecules of this class can be divided into two groups: E series and P series which correspond to ethylene and propylene respectively. Glycol ethers are selected for specific purposes, such assolubility, inflammability, andvolatility

Diacetone alcoholis achemical compoundwith the formula CH₃C(O)CH₂C(OH)(CH₃)₂, sometimes called DAA. This liquid is a commonsyntheticintermediate used for the preparation of other compounds, and is also used as a solvent.

It is used incelluloseesterlacquers, particularly of the brushing type, where it produces brilliant gloss and hard film and where its lack of odor is desirable. It is used inlacquer thinners, dopes, wood stains, wood preservatives and printing pastes; in coating compositions forpaperand textiles; permanent markers;^[6]in making artificialsilkandleather; in imitation gold leaf; in celluloidcements; as a preservative for animal tissue; in metal cleaning compounds; in the manufacture of photographic film; and in hydraulicbrake fluids, where it is usually mixed with an equal volume ofcastor oil.

o-Xylene(ortho-xylene) is anaromatichydrocarbonwith the formula C₆H₄(CH₃)₂. with twomethylsubstituentsbonded to adjacent carbon atoms of a benzene ring (theorthoconfiguration). It is aconstitutional isomerofm-xyleneandp-xylene, the mixture being called xylene or xylenes.o-Xylene is a colorless slightly oily flammable liquid.

o-Xylene is largely used in the production ofphthalic anhydride, which is a precursor to many materials, drugs, and other chemicals

Xylene(from Greek, xylo, "wood"), xylolordimethylbenzeneis any one of threeisomersof dimethylbenzene, or a combination thereof. With the formula (CH₃)₂C₆H₄, each of the three compounds has a centralbenzenering with twomethyl groupsattached atsubstituents. They are all colorless, flammable liquids, some of which are of great industrial value. The mixture is referred to as both xylene and, more precisely, xylenes.

Xylene is used in the laboratory to make baths with dry ice to cool reaction vessels, ^[15]and as asolventto remove syntheticimmersion oilfrom the microscopeobjectiveinlight microscopy.^[16]Inhistology, xylene is the most widely used clearing agent.^[17]Xylene is used to remove paraffin from dried microscope slides prior to staining. After staining, microscope slides are put in xylene prior to mounting with a coverslip.
