A floor care composition includes pre-made polymer particles in a liquid vehicle as well as a non-ionic crosslinking agent. The polymer particles include a relatively narrow ratio of hydro-philic to hydrophobic regions or components, a generally non-uniform morphology, and a relatively small number of carboxyl groups. When used in floor care formulations with the correct amount and type of crosslinking compounds, a resulting floor care finish can be both resistant to alcohols such as ethanol and readily removable.
