Propylene glycol is a synthetic liquid substance that
absorbs water. Propylene glycol is also used to make polyester compounds, and
as a base for deicing solutions. Propylene glycol is used by the chemical,
food, and pharmaceutical industries as an antifreeze when leakage might lead to
contact with food. The Food and Drug Administration (FDA) has classified
propylene glycol as an additive that is “generally recognized as safe” for use
in food. It is used to absorb extra water and maintain moisture in certain
medicines, cosmetics, or food products. It is a solvent for food colors and
flavors, and in the paint and plastics industries. Propylene glycol is also
used to create artificial smoke or fog used in fire-fighting training and in
theatrical productions. Other names for propylene glycol are 1,2-dihydroxypropane,
1,2-propanediol, methyl glycol, and trimethyl glycol. Propylene glycol is
clear, colorless, slightly syrupy liquid at room temperature. It may exist in
air in the vapor form, although propylene glycol must be heated or briskly
shaken to produce a vapor. Propylene glycol is practically odorless and
tasteless.
Propylene glycol, also called 1,2-propanediol or propane-1,2-diol, is an organic
compound (a diol or double alcohol) with formula C3H8O2. It is a colorless, nearly
odorless, clear, viscous liquid with a faintly sweet taste, hygroscopic and
miscible with water, acetone, and chloroform. The compound is sometimes called
α-propylene glycol to distinguish it from the isomer propane-1,3-diol (β-propylene glycol).
45%
of propylene glycol produced is used as chemical feedstock for the production
of unsaturated polyester resins. In this regard, propylene glycol reacts with a
mixture of unsaturated maleic anhydride and isophthalic acid to give a
copolymer. This partially unsaturated polymer undergoes further crosslinking to
yield thermoset plastics. Related to this application, propylene glycol reacts
with propylene oxide to give oligomers and polymers that are used to produce
polyurethanes. Propylene glycol is considered generally recognized as safe (GRAS)
by the U.S. Food and Drug Administration, and it is used as an humectant (E1520), solvent, and
preservative in food and for tobacco products, as well as being one of the
major ingredients of the liquid used in electronic cigarettes. It is also used
in pharmaceutical and personal care products. Propylene glycol is a solvent in
many pharmaceuticals, including oral, injectable and topical formulations, such
as for diazepam and lorazepam that are insoluble in water, use propylene glycol
as a solvent in their clinical, injectable forms. Like ethylene glycol,
propylene glycol is able to lower the freezing point of water, and so it is
used as aircraft de-icing fluid. Water-propylene glycol mixtures dyed pink to
indicate the mixture is relatively nontoxic are sold under the name of RV or
marine antifreeze. It is also used to winterize a vacant structure.[9] The eutectic
composition/temperature is 60:40 propylene glycol:water/-60°C.[10][11] The -50°F/-45°C commercial product is,
however, water rich; a typical formulation is 40:60. Propylene glycol is a
minor ingredient in the oil dispersant Corexit, used in great quantities during
the Deepwater Horizon oil spill.

Food and Flavorings
Pet Food/Animal Feed
Pharmaceutical
Other Applications
Heat Transfer Fluids, with a suitable inhibitor package,
makes an excellent choice for use as a heat transfer fluid in applications
where contact with potable water, food or beverages might occur. Its low
toxicity, low freezing point and high boiling point make it uniquely applicable
for use in such applications.
Fragrance, Cosmetics and Personal Care
• Solvents,
carriers, emollients, dispersants, coupling agents and co-emulsifiers, emulsion
stabilizers or viscosity modifiers
• Humectants
due to their hygroscopic nature and ability to attract and hold water
• Preservatives
due to inherent antimicrobial activity against a wide range of bacterial and
fungal species
propylene glycols are commonly used in many types of
cosmetic formulations such as:
• Skin
care (creams, moisturizers, cleansers, lotions, sun care products)
• Deodorants
and antiperspirants (roll-on, stick and gel deodorants)
• Hair

Application
Use
Dust suppression
Dust formation and the associated housekeeping issues,
plus the danger of dust explosions, make dust suppression important in mining
and cement grinding applications. Propylene Glycol Industrial Grade (PGI)
provides good wetting ability, hygroscopic nature, low vapor pressure and low
toxicity, and is ideal for use as a dust suppression agent.
Dyes and Inks
Propylene glycols are excellent solvents and
compatibilizers for the many dyes, resins and inks used in modern high-speed
printing presses. System requirements determine the choice of propylene glycol
product:
•Propylene Glycol
Industrial Grade (PGI) is the best choice for polar formulation
•Dipropylene
Glycol Regular Grade (DPG) is used for intermediate polarity formulations
•Tripropylene
Glycol Regular Grade (TPG) is used for inks with higher-hydrocarbon makeup
•DOW PuraGuard™
Propylene Glycol USP/EP is recommended for applications where there is possible
direct or indirect food contact
Lubricants
Dipropylene Glycol Regular Grade (DPG) has an affinity
for oils that makes it an ideal component of textile lubricant formulations. It
is also approved by the FDA for indirect usage as a surface lubricant in metal
part manufacture (21CFR178.3910). The water solubility and solvency properties of
Tripropylene Glycol Regular Grade (TPG), along with its low volatility and high
boiling point make it especially useful in lubricants.
Natural Gas Dehydration
When natural gas is
recovered, its water content may need to be lowered to prevent water from
condensing in pipelines and freezing, or from forming hydrocarbon hydrates.
Hydrates can foul instruments and reduce line capacity. The hygroscopic nature
of Propylene Glycol Industrial Grade (PGI) makes it an effective dehydrating
fluid for use in the natural gas processing industry.
Plasticizers
A plasticizer is a molecule that is added to a polymer to
modify its properties, making it easier to process and/or meet application
requirements such as improved toughness or flexibility. Plasticizers function
by internal solvation of the polymer chains. Dipropylene Glycol Regular Grade
(DPG) is reacted with phthalic acid or anhydride to form the dipropylene glycol
phthalate; one of the most important plasticizers for polyvinyl chloride (PVC)
resins.
Surfactants
"Surfactant"
is a contraction of the words surface-active and agent. Surfactants function by
changing the surface tension at the interface of mixtures, allowing
non-miscible materials to either be dispersed into water or separated from
water. Propylene glycols are used as initiators for synthesis of nonionic
surfactants made from polymerization of ethylene oxides with other oxides such
as propylene or butylene oxides. Propylene glycol is also used as the starting
material for the synthesis of propylene glycol esters with sorbitol and/or
fatty acids.
Waxes
Tripropylene Glycol Regular Grade (TPG) and Dipropylene
Glycol Regular Grade (DPG) are used to provide freeze-thaw protection in
various wax products to help prevent damage caused by freezing.
