StorageStore at 0 degrees Celsius or colder.Unopened product best if used within 24 months of receipt. Once opened, best if used within 6 months. To enhance the stability of remaining material after product is opened, gently purge the product with an inert gas such as nitrogen or argon, which will remove oxygen which can cause oxidation of the Monoolein, before sealing.

SolubilitySoluble in chloroform (50 mg/ml). Soluble in Hexane and can be crystallized from Hexane. In water, Monoolein tends to form a gel or emulsion.
