> “Since ethanol is the main component of hand sanitizer, we believe it is possible to de-bond and recycle the adhesive by using hand sanitizer as a substitute in certain real-world situations,” Aida says.
These sorts of environmental impact blurbs are hilarious. What kind of scenario are they envisioning where someone wants to remove and reuse a specialized adhesive bonding PTFE parts to something, but don't have ethanol on hand and have to fall back to using hand sanitizer?
Hand sanitizer is also contaminated with other crap... presumably that impacts the adhesive if you're attempting to "recycle" it? I agree, what a weird line.
One example might be ungluing a lithium pouch cell (usually polyamide film outer surface, which is a pretty low-surface-energy polymer) for home replacement. Electrically-debonded adhesives are a better option here, but not sure what the cost trade-offs look like.
Gelled solvents are useful for softening adhesives in certain situations far better than the pure substance
Maybe a 2026 remake of MacGyver?

Who says this will be a specialized adhesive? If it works as advertised, it could be a super-glue alternative with easy unglueability. That would be an attractive consumer product; and the type of product that could easily end up on someones hands.
