- Dow Propylene Glycol USP K is a widely used ingredient in pharmaceutical, food, cosmetic, personal care, flavors and animal feed applications; an overview of typical uses of product is given below.
- It must be emphasized that it is the user’s responsibility to consult area and country-specific regulations for details of approved use.
- Pharmaceuticals - Solvent for active ingredients in oral, and topical products.
- Cosmetics & Personal Care - Solvent, coupling agent, carrier, emulsion stabilizer, softening agent, viscosity modifier and humectant in many types of cosmetics and personal care products such as skincare, sun care, shampoo, bath/shower products, toothpastes, mouthwashes, shaving products and baby care products.
- Flavors & Fragrances - Solvent and extraction solvent of flavors and fragrances for applications in food, beverages, perfumes and cosmetics.
- Food - Various applications as a direct food additive (E 1520), such as a carrier or carrier solvent for colors, emulsifiers, antioxidants and enzymes (in Europe with maximum 1 g/kg in human foodstuffs), and humectant and stabilizer in fruits, vegetables and bakery goods (except in Europe). PG USP/EP is also applied in indirect contact food applications, such as a low temperature heat-transfer fluid in the brewing, dairy and ice cream industries and for food storage facilities, an equipment cleaner fluid or a solvent for printing inks.
- 5.Pet foods & Animal Feed - Humectant, emulsifier, preservative, solvent for additives, energy source and aid for prevention of ketosis (acetonemia) in dairycattle. In EMEA a specific tailor made Propylene Glycol Animal Feed is offered for this application (for details see Product Technical Data Sheet).

Storage & Handling
- Storage Information
Dow Propylene Glycol USP K is stable for at least two years when stored at ambient temperatures in closed containers and away from sunlight and other sources of UV light.
Where product heating is utilized (i.e. for bulk storage and/or transport containers) the product temperature should be controlled to prevent unintentional overheating over extended periods as this may potentially lead to accelerated oxidative degradation of the product. As a general guide Dow recommends heating up to not more than 40°C.
