Flour has both polar and non-polar molecules in it. However, most cooking flours have more non-polar molecules, which is why they distribute more evenly in non-polar liquids (like melted butter) than polar (water).
Skin is a heterogeneous mixture, composed of many different cells, which are composed of many different compounds. Polarity is decided by the configuration of the molecule. Because it is made of many different molecules, it is neither.
Unless it's substituted with polar groups, propane, like all alkanes, is non-polar.

oil typically comprises of long chained hydrocarbon molecules (hydrocarbons are substances made entirely from hydrogen and carbon). these hydrocarbon chains are hydrophobic, that is they are imiscible with water, they 'don't like' coming into contact with water. Hence, when oil is added to water, (or vice versa) two distinctive phases are observed. In addition to this oil and water are immiscible because oil molecules are nonpolar and water molecules are polar. Whether a solute dissolves or not can be answered by the statement "like dissolves like".That is, if a solute and solvent are both polar (or both nonpolar), then the solute will disolve.
Like dissolves like. Polar compounds dissolve in polar solvents and nonpolar compounds dissolve in nonpolar solvents. An exception to this rule, however, is that an electronegative atom can only take four or five carbons into a polar solvent. An alcohol with an alkyl chain seven carbons long, for example, will not be soluble in a polar solvent, even though it is a polar molecule.
Nonpolar molecules have no net dipoles. The most common nonpolar molecules are hydrocarbons. These are molecules made entirely of carbon and hydrogen atoms.
A polar and a nonpolar substance being made miscible together by another substance that has both polar and nonpolar characteristics.
Substances are hydrophobic because they are nonpolar. Nonpolar molecules are made up of elements with little difference in their electronegativities so they do not have charges or partial charges. Water is a polar molecule so it tends to be attracted to other molecules that are polar as well. This is often summed up as "like attracts like". Some examples of hydrophobic molecules include fats and oils which are nonpolar because they have large hydrophobic hydrocarbon chains.
