Solvents & Glycols



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.

Recommended use:

  • Solvent for chemicals, paints, coating, adhesive, printing ink, varnishes, gums, resins, essential oils.
  • Solvent for the preparation of copolymers.
  • Used in the preservation of physiological and pathological specimens.
  • Used for extraction processes, perfumery, and pharmaceuticals.
  • Used in the production of acetone, glycerol and isopropyl esters, acetate.
  • Used for disinfectant, pharmaceuticals, perfumery.
  • Used for cosmetic products and personal care.




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 :

  • Solvent for nitrocellulose, resins, dyes, oils, other organic compounds.
  • Manufacture of unsaturated polyester resins, polyurethanes, plasticizers.
  • As a building block in organic synthesis, e.g. of morpholine and 1,4-dioxane.
  • A humectant for tobacco, cork, printing ink, and in brake fluid.
  • Used in human medications, such as acetaminophen and sulfanilamide.




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:

  • As a solvent for many substances, both natural and synthetic.
  • Used as chemical feedstock for the production of unsaturated polyester resins.
  • Approved by Food Drugs Administration (FDA) for certain uses as an indirect food additive.
  • As a humectant.
  • As an antifreeze.
  • For pharmaceuticals, cosmetics and personal care.


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.
