Since there's already an effect of players taking fire damage and burning with a hot container, there should be slowness and frost burn damage to players that are carrying super cold liquids.

I had mentioned Astral Sorcery's liquid starlight, but sort of conflicted as it is supposed to be a super cold liquid; however, if a player interacts with it, all that happens is that they get night vision for a few seconds and no damage is given. Other mods, like the Thermal series, do have super cold liquids such as gelid cryotheum, which does give damage on contact.

See what you think and thanks again.
