"E" on cosmetic packaging
In some imported cosmetics, "e" often appears on the outer packaging, such as: 20ml e 0.67 FL OZ, 150ml e, where the "e" represents the meaning: cosmetics cannot be filled in exactly the same way, such as items The weight is marked as 100ml on the package, but it may be slightly more or less. Therefore, the sign ℮ will be added to indicate that 100ml is an estimate, not an absolute amount. ℮ represents the first letter of estimate. The e standard stipulates that for products with a total standard weight of less than 50g (ml), the actual error is allowed within 9% (including 9%). For products with a total nominal weight of more than 1kg, the actual error allowed is within 1.5% (including 1.5%).
