What advantage might the commercially packaged coolant material have over ice other than that it produces less mess?

Commercially packaged coolant materials often have a more consistent and sustained temperature compared to ice, which can quickly melt and lose its cooling effect. Additionally, these materials are typically designed to be lightweight and portable, making them easier to handle and transport. They may also offer better thermal conductivity, allowing for more efficient cooling in specific applications. Lastly, they can be reusable, providing a longer-lasting solution compared to single-use ice.
