if you are talking about oil droplets its because oil is made up of long hydrocarbon chains
these chains are nonpolar which means that all sides have the same electron distribution
Water however is a very polar bent molecule. There is more electon density on the oxygen.
Like dissolves like is the phrase commonly used. This means that polar solvents dissolve(mix with) polar solutes where nonpolar solvents dissolve nonpolar solutes. This is due mostly to hydrogen bonding or lack there of. Hydrogen bonding is interactions between poles in a polar solvent. So the hydrogen of one water molecule line up with the oxygen of another which lines up with a hydrogen of another and so on.
and yes the floating is because of density if the droplets were more dense then theyd sink but still not mix.

Droplets of what? Droplets of water will mix with water. The only reason any kind of droplets won't mix with water is if they're non-polar. (Water is polar.)

The droplets are so small that their surface tension keeps them apart.

The density of droplets is less than water.
