in the food we eat every day. Dow Propylene Glycol USP/EP1

offers one of the highest puritypropylene glycols available in the marketplace with a specified purity of 99.8 percent or

greater, non-detectable MEG/DEG2 contents, adherence to IPEC-PQG3 Good Manufacturing

Practices for pharmaceutical excipients, and a two-year shelf life when stored according to

Dows recommendations.Think of it as yoursecurity for purity.

Dow PG USP/EP offers excellent stability and versatility

as a food additive in a wide variety of direct and indirect

food-processing applications.

Direct Food Applications

Solvent and carrier in many flavor formulations for the

processed food and beverage industry Solvent and carrier for colors, anti-oxidants, enzymes

and emulsifiers

Plasticizer and softening agent for food-contact items such as cork seals

Flavor extraction solvent and processing aid in the isolation of natural

flavoring materials (extracting vanilla from vanilla beans, for example)

Humectant and stabilizer in prepared fruits, vegetables and bakery goods

(except in Europe)

Purity is essential

1Dow PG USP/EP is tested against and complies with the specific requirements of current USP, EP and JP.It also meets, but is not tested against, Brazilian Pharmacopeia requirements. Dows stringent PG USP/EPglobal manufacturing standards offer the availability of the same consistently pure, high-quality PG USP/EP product around the world.2Monoethylene Glycol/Diethylene Glycol.3International Pharmaceutical Excipients Council/Pharmaceutical Quality Group.4When stored below 104 F (40 C) in closed containers, protected from UV light.

Excellent Quality for

Pure CondenceDow Propylene Glycol USP/EP offers high quality andconsistency, according to the industrys most stringent

quality-control processes, including adherence to Good

Manufacturing Practices (GMP) from The Joint IPEC-PQC

Good Manufacturing Practices Guide for Pharmaceutical

Excipients. Dows commitment to GMP throughout the

supply chain enables Dow PG USP/EP to be handled

according to stringent requirements for consistent purity.

Dow PG USP/EP is tested against and certified according

to the requirements for the following standards:

Food Chemicals Codex (FCC)

United States Pharmacopeia (USP)

European Pharmacopeia (PhEur or EP)

Japanese Pharmacopeia (JP)

Dow PG USP/EP is a clear, colorless, practically

odorless, slightly viscous, water-soluble and hygroscopic

liquid. It is synthesized from hydrocarbon raw materials.

Materials of plant or animal origin, genetically modified

organisms, solvents, catalysts, additives or stabilizers

are not used in the manufacturing process or added to

the final product.

Dow PG USP/EP is manufactured without any known

allergy-stimulating food substances.

Dow Propylene Glycol USP/EP complies with various requirements of food applications in different

global geographies:

Cleared for various direct and indirect food applications under U.S. FDA Food Additive Regulations.

Generally Recognized As Safe (GRAS) by the U.S. FDA according to 21 CFR 184.1666.

Not approved as a multi-purpose food additive in the European Union:

Regulated by European Parliament and Council Directive No. 95/2/EC on food additi ves other than colors and

sweeteners, and subsequent amendments.

Assigned E number E1520.

Allowed as a carrier/carrier solvent for colors, emulsifiers, antioxidants and enzymes, with a maximum

allowed level of 1 g/kg (0.1 percent) in the final foodstuffs.

Allowed in flavorings, with a maximum allowed level of 3 g/kg, from all sources in foodstuffs as consumed or

as reconstituted according to the instructions of the manufacturer, individually or in combination.

Allowed in flavorings for beverages (with the exception of cream liqueurs, the maximum level allowed is 1 g/l).

Fulfills the purity criteria for E1520, propane-1,2-diol, detailed in the European Commission Directive 2008/84

EC for food additives, other than colors and sweeteners.7

Fulfills the food additive specification of JECFA (Joint FAO-WHO Expert Committee on Food Additives) Propylene

Glycol Monograph 1 (2006).8

Is certified Kosher (Parve) for year-round use, including Passover (Pesach) and also certified Halal in most Dow

PG production plants worldwide.

Dow supports the use of its PG USP/EP product only for all direct and indirect food applications of propylene glycol.

Applicable local government regulations should be consulted for details on approved and appropriate applications.

Because Dow PG USP/EP is manufactured by Dow according to the guidelines defined in the IPEC-PQG Good

Manufacturing Practices Guide for Pharmaceutical Excipients and the IPEC-PQG GMP guidelines are more stringent

than the principles of the Hazard Analysis and Critical Control Point (HACCP) program, Dow has determined that an

HACCP plan for PG USP/EP is unnecessary.
