Isopropyl alcohol (IPA) is a clear, colorless, volatile and flammable material with a strong odor. Isopropyl alcohol is also known as 2-propanol, sec-propyl alcohol, IPA, or isopropanol.
Diethylene Glycol (DEG) is a colorless, low volatility, low viscosity, hygroscopic liquid. It is completely miscible with water and many organic liquids.
The reactivity and solubility of diethylene glycol provide the basis for many applications. These are :
Propylene glycol is a synthetic liquid substance that absorbs water. It is miscible with a broad range of solvents, including water, acetone, and chloroform. In general, glycols are non-irritating, have very low volatility and very low toxicity.
Propylene glycol has many applications. Some common applications see PG used:
Polyethylene Glycol (PEG) is non-toxic, colorless, inert, odorless, and non-volatile. Also, it is incredibly soluble in water, and organic solvents such as benzene, carbon tetrachloride, and chloroform.
Polyethylene glycol has a various applications :
1. Uses in the medical industry
Due to its non-toxicity and approved by Food Drugs Administration (FDA), Polyethylene Glycol can be used for drug delivery, basis of a number of laxatives, and many more.
2. Uses in the chemical industry
Can be used as a binding and dispersing agent, as it can improve the separation of particles and prevent clumping. Applications in preservation have also found a use for PEG. Because the compound is non-toxic and recognized as safe by the FDA, it has been able to be used in numerous coatings that enable lubrication in various scenarios.
