Why does fast-dry nail polish dry fast?
In: 13
They’ve adjusted the ratios of ingredients as well as maybe slightly altering the formula. Solvents are the stuff that holds it all together until dried, and are also the part that needs to flash off to be dry. More solvent means flashing off more quickly, and they toss in another film former (the ingredient that makes the finish smooth) to make sure it gets smooth before getting dry.
For those top coat drops, it’s just stuff that absorbs the solvents out of the polish to make it dry faster and helps it evaporate faster. It acts essentially like a sponge.
