Why do cereal stay crunchy for relative longer when drenched in milk compared to regular cookies that just go soggy almost instantly

Question

Got a bunch of cookies left over the other day, decided to crush them up and eat them as cereal. I always add milk first and cereal second, but they all went soggy after about 10 seconds.

“Oh the Crunch enhancer? Yeah it’s a non-nutritive cereal varnish. It’s semi-permiable. It’s not osmotic. What it does is it coats and seals the flake, prevents the milk from penetrating it.”
