Without checking out the details, I can say with fairly high confidence that a material that will be degraded by a sodium chloride solution will most likely also be degraded by other electrolytes as well.

However, the electrolyte-concentration in drinks is much, much lower than that in seawater. And if it can't be used for electrolyte-containing drinks, it could be used for water bottles.

Maybe we could use this stuff for umbrellas too? My major concern is what this new material is broken down into.
