Reply to comment by UncommercializedKat in What can you add to a bottled drink to lower the freezing point (other than salt)? by UncommercializedKat

I'm very curious why you're asking this. It seems oddly specific, like you're trying to play a prank.

You might consider supercooling depending on what your exact needs are:

You can end up with a liquid at a temperature lower than normal without any chemical changes.

But I do think there might be options besides freezing point depression if you give more detail about the expected outcome instead of just the method you're asking about.

No pranks. I have an idea for a consumer product and I'm researching the viability.

What I'm looking for is to make a sports drink that would be resistant to freezing. I don't have a specific temperature in mind, although it would be really great if it could be kept from freezing in a normal household freezer (0F or -18C).

Cost, taste, and food safety are all vital so I'm not sure how low it could feasibility go. I've heard that Gatorade freezes at 18F (-8C) but haven't done any experimenting.

Gastrointestinal problems might be real concern, when you start adding additives to reduce the freezing point. Osmotic diarrhoea is a nasty thing.
