Abstract
The invention presents a fast-drying nail polish topcoat composition with high shine and long wear. The disclosed combination of at least two cellulose-derived primary film formers, a ketone-aldehyde resin, a plasticizer, a hydrocarbon oil, and solvents selected such that no more than 20% of the solvents have an evaporation rate less than or equal to butyl acetate provides a nail polish that can be dried within 30 seconds on fingernails without sacrificing other critical properties.
