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

Thanks for the info!

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.
