Propylene Glycol

Mono Propylene Glycol USP/IND also known as propane-1,2-diol is a colorless, odorless liquid which is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) in 21 CFR § 184.1666, for use as a direct food additive under the conditions prescribed. It is approved by the U.S. FDA for certain indirect food additive uses.

Ethylene Glycol (also known as MEG) is a clear, colorless, virtually odorless, and slightly viscous liquid. It is miscible with water, alcohols, and many organic compounds, and has the formula C₂H₆O₂. It is the most important of the commercially available ethylene glycols as it has many industrial applications.

Application:

Ethylene Glycol as it is a vital ingredient in the production of polyester fibers, films, and resins, one of which is polyethylene terephthalate (PET). The second largest market for MEG is in antifreeze applications where it is a component in the manufacture of antifreeze, coolants, aircraft anti-icer, and de-icers.

Ethylene Glycol also has humectant properties and this makes it ideal for use in the fibre treatment of textiles, the paper industry, and in adhesives, inks, and cellophane. Ethylene Glycol is also a used as a dehydration agent in natural gas pipelines where it inhibits the formation of natural gas clathrates before being recovered from the gas and reused.

Polyethylene glycols (poly-oxyethylene) meets Indian and international pharmacopoeia, such as IP / USP / NF / (PEG) specifications. These are essentially non-toxic, stable and versatile solvents that find application in the pharmaceutical, cosmetic, oral care, automotive, textile, paint, printing, resin and plastic, and ceramic industries.
