- Industrial propylene glycol
Propylene glycol enables a large variety of consumer and industrial applications: In food and beverage, feed, cosmetics and pharmaceutical applications, propylene glycol USP/EP (pharmaceutical grade) is used, for example, to dissolve flavouring in drinks, to keep animal feed moist, to homogeneously emulsify oily and watery elements in creams, sprays and liquids, or as solvent (excipient) for the active ingredients in medicines.
In industrial applications propylene glycol is used as an intermediate to make other chemical substances, such as the unsaturated polyester resins which are used in bath and kitchenware, pipes or windmill blades. It is also used to manufacture plastics, resins, paints and coatings, and plays an important role as an ingredient of formulations for heat transfer fluids, liquid detergents or aircraft de-icing.
