Perfume and Flavor Chemicals, page 1181.
Colorless, slightly viscous liquid.
Miscible with water, glycerin, alcohol and most of the common perfume and flavor oils, but not in terpenes and many other hydrocarbons, poorly in aromatic allyl- and propenyl-derivatives. Practically insoluble in vegetable oils and fats.
Odorless when absolutely pure.
Mild, sweet taste in aqueous solution, slightly burning or warm mouthfeel when undiluted. The aqueous solution may also leave a delayed burning feeling in the rear of the mouth.
Propylene glycol is occasionally used as a diluent in perfume compositions, but it is not considered the very best solvent for such purpose. It has practically no fixative value.
It finds very extensive use as a diluent or solvent in flavor compositions, mainly due to its low toxicity, absence of color and odor and to its mild, sweet taste.
