Water is life—this isn’t just a saying, but a scientifically proven truth. The chemical formula of water is H₂O, consisting of two hydrogen atoms and one oxygen atom. But have you ever wondered if water has an expiry date? This question often arises, especially when you see a date printed on bottled water packaging. However, does water actually have a real expiry date? The answer is no.
The ‘expiry date’ printed on bottled water is not for the water itself but for the plastic bottle. According to Indian standards, plastic bottles generally remain safe for only six months to retain their properties. After this period, the plastic gradually begins to release chemicals, which can contaminate the water. Therefore, experts advise against using bottled water that is older than six months. However, if the bottle is stored in a cool, dark, and dry place, its shelf life may be slightly extended. It’s important to note that the safety of the water depends on the quality of the plastic bottle and how it is maintained.
