Dasani water is one of the most widely consumed bottled water brands globally, owned by The Coca-Cola Company. While it’s known for its purity and taste, there’s a common myth circulating online that Dasani water doesn’t freeze. But is this claim true? In this article, we’ll delve into the science behind freezing water, the properties of Dasani water, and the possible reasons why some people believe it doesn’t freeze.
Understanding the Freezing Process of Water
Before we dive into the specifics of Dasani water, it’s essential to understand how water freezes in general. Freezing is a natural process that occurs when water is cooled to a temperature at or below its freezing point, which is 0°C (32°F) at standard atmospheric pressure. During this process, the molecules in the water slow down and come together to form a crystal lattice structure, which is characteristic of ice.
The Role of Impurities and Dissolved Gases
The presence of impurities and dissolved gases in water can affect its freezing point. For example, if water contains high levels of dissolved salts or minerals, its freezing point can be lower than 0°C (32°F). This is known as “freezing-point depression.” On the other hand, if water is highly purified, it can freeze at a slightly higher temperature than 0°C (32°F) due to the absence of impurities.
The Effect of Pressure and Temperature
Pressure and temperature also play a crucial role in the freezing process of water. At higher pressures, water can remain in a liquid state even below its freezing point, a phenomenon known as “supercooling.” Conversely, if water is cooled slowly and carefully, it can freeze at a temperature slightly above its freezing point, a process known as “superheating.”
The Properties of Dasani Water
So, what makes Dasani water unique? Dasani is a purified water brand that uses a combination of reverse osmosis, ultraviolet (UV) light, and filtration to remove impurities and minerals from the water. This process results in water that is highly purified and has a neutral pH level.
Dasani Water’s Purification Process
Dasani’s purification process involves the following steps:
- Reverse Osmosis: This process uses a semipermeable membrane to remove impurities and minerals from the water.
- UV Light: The water is then exposed to UV light to kill any remaining bacteria or viruses.
- Filtration: The water is filtered again to remove any remaining impurities.
Dasani Water’s Chemical Composition
Dasani water has a very low total dissolved solids (TDS) level, which means it contains very few minerals and impurities. According to the Dasani website, their water has a TDS level of less than 10 parts per million (ppm).
Does Dasani Water Not Freeze?
Now that we’ve explored the properties of Dasani water, let’s address the question of whether it freezes. The short answer is yes, Dasani water does freeze. However, there are some possible reasons why some people may believe it doesn’t:
Supercooling and Superheating
As mentioned earlier, water can remain in a liquid state even below its freezing point if it’s cooled slowly and carefully. This is known as supercooling. If Dasani water is supercooled, it may not freeze immediately, leading some people to believe it doesn’t freeze at all.
Lack of Nucleation Sites
Dasani water’s high purification level means it lacks nucleation sites, which are tiny imperfections in the water that can act as a catalyst for freezing. Without these nucleation sites, the water may not freeze as easily, leading some people to believe it doesn’t freeze.
Container and Storage Conditions
The container and storage conditions of Dasani water can also affect its freezing behavior. If the water is stored in a container that’s not conducive to freezing, such as a plastic bottle with a smooth surface, it may not freeze as easily.
Conclusion
In conclusion, Dasani water does freeze, but its high purification level and lack of nucleation sites may affect its freezing behavior. While it’s possible that some people may have experienced instances where Dasani water didn’t freeze, this is likely due to supercooling, superheating, or other environmental factors rather than any inherent property of the water itself.
Final Thoughts
The myth that Dasani water doesn’t freeze is an interesting example of how misinformation can spread online. By understanding the science behind freezing water and the properties of Dasani water, we can debunk this myth and appreciate the complexities of the natural world.
Whether you’re a fan of Dasani water or just curious about the science behind freezing, we hope this article has provided you with a deeper understanding of this fascinating topic.
What is Dasani water and why is it so popular?
Dasani is a popular brand of bottled water owned by The Coca-Cola Company. It was introduced in 1999 and has since become one of the leading bottled water brands in the United States. Dasani water is purified using a multi-step process that includes reverse osmosis, ultraviolet (UV) light, and filtration. This process removes impurities and minerals from the water, resulting in a neutral-tasting and odorless product.
The popularity of Dasani water can be attributed to its widespread availability, affordable price, and effective marketing campaigns.

Many people also prefer Dasani water due to its neutral taste and lack of strong odor, making it a popular choice for everyday consumption.
What is the mystery behind Dasani water not freezing?
The mystery behind Dasani water not freezing is largely anecdotal, with many people claiming that the water does not freeze even when placed in a freezer. However, there is no scientific evidence to support this claim. In reality, Dasani water is just like any other water and will freeze at 0°C (32°F) under normal conditions. The reason why some people may think that Dasani water does not freeze is due to the presence of additives or the purification process, which can affect the freezing point of the water.
It’s worth noting that the freezing point of water can be affected by various factors, including the presence of impurities, the temperature of the freezer, and the container in which the water is stored. However, there is no conclusive evidence to suggest that Dasani water is immune to freezing. In fact, many experiments have been conducted to test the freezing point of Dasani water, and the results have shown that it freezes just like any other water.
What additives are present in Dasani water?
Dasani water contains a few additives, including potassium chloride, magnesium sulfate, and calcium chloride. These additives are used to enhance the taste and mouthfeel of the water.
