Why does powdered coffee creamer dissolve easily in fresh, hot coffee but not reheated, hot coffee?

247 views

I’m new to using powdered coffee creamer, but I’ve noticed that, with a spoon to stir, it mixes instantly with a fresh pot of coffee but 30 minutes or an hour when I go to pour the second cup, it clumps up and can’t be mixed. Same result when I keep the pot heated and/or when I reheat the mug in a microwave.

The solubility of powders typically increase in hot liquids also dehydrated milk has some oils that are not easy to disperse and disolve in cold liquids that is why it clumps up as the outside gets wet but the inside still dry. It is possible to get it inot solution but it requires a lot of fast stirring.
