While silicone is generally a safe and durable material for silicone water bottle, there are some liquids that you should avoid storing in them for extended periods of time. 

Here are some examples:

1. Citrus juices: Citrus juices, such as orange or grapefruit juice, can react with the silicone and cause the Collapsible Silicone water bottle to break down over time. This can lead to a change in the taste or odor of the liquid.

2.Alcoholic beverages: Alcoholic beverages can also react with the silicone and cause it to break down. In addition, the alcohol can cause the folding silicone water bottle to retain a strong odor.

3.Dairy products: Dairy products, such as milk or yogurt, can spoil quickly and cause the foldable water bottle silicone to develop a strong odor. These liquids can also leave a residue that is difficult to clean.

Overall, it's best to stick to storing water or other plain liquids in a reusable silicone bottle for extended periods of time. If you do want to store other liquids, make sure to clean the silicone bottle thoroughly after each use to prevent odors or residue from developing.
