Are suitcases waterproof?

the presence of fats, oils, or waxes, as all three of those are hydrophobic - that is, resistant to moisture

a suitcase is a object that you can take on holiday.

Any mascara that says "water proof" on the side - usually is waterproof! Try Clinique, Covergirl, Avon, Maybelline, Lancome... ect. These water proof mascaras are best removed by 'makeup remover...

The solution cannot be dissolved in water (insoluble in water). That's why to clean your hands really well you must use soap because it can dissolve the oils.

Well for the most part yes.My babysitter wears it all the time in the pool.plus its hard to get off.
