Meaning of the Open Jar Symbol
Have you ever noticed a tiny icon on your cosmetic products that looks like an open container with a number followed by the letter ‘M’ inside? That’s the Open Jar Icon, commonly known as the Period After Opening (PAO) symbol. It’s there to tell you how long you can expect your cosmetic product to stay in good condition after you’ve first used it.
For instance, spotting a “12M” inside the jar suggests that your product is best used within 12 months from when you first open it. It’s a straightforward way to help you keep track of your product’s freshness and efficacy.
When to use the Open Jar Symbol
In the U.S., the Food and Drug Administration (FDA) does not mandate the inclusion of expiration dates on cosmetic products’ labels.
Contrastingly, the European Union takes a more stringent approach to cosmetic labeling:
For Long-lasting Products: Cosmetics with a lifespan exceeding 30 months must feature the Open Jar Icon instead of a specific expiration date. This symbol guides users on the duration a product remains usable after first opening.
For Shorter Lifespan Products: Products that will last up to 30 months require a clear expiration date on their packaging, without the need for the Open Jar Icon.
Moreover, the EU rules provide some flexibility under particular circumstances, such as for cosmetics that are sealed, dispensed as sprays, intended for a single use, or are unlikely to deteriorate.
