Unopened containers have at least 5 years of shelf life under ordinary conditions. Best to keep away from light for long storage periods. Under ideal conditions, the shelf life has been proven to be 8 years.
Opened containers should be used up within 4-6 months. The key here is to open one container and use it up, rather than having several open containers.
Equinell™ Oil will darken with exposure to air or sunlight. When fresh, it is a light to medium amber color. With exposure, it will turn a light brown. It is still useable at this point. With further exposure, it will turn dark brown and is no longer good. Storing in the refrigerator or freezer will not significantly prolong product life. Neither heat nor cold affects the Equinell™ products.
