Wax has theoretically an unlimited shelf life, however many additives (flavor, softener, etc.) can affect it negatively. Since both synthetic and natural waxes are used in various products, such as cosmetics and foods, expiry dates have to be specified. The oxidation stability can give an approximate indication for the shelf life. A reproducible and accurate determination of the oxidation stability using the 892 Professional Rancimat can be realized.
