  • Liquid composition used for dissolving fingernail polishes
    Patent number: 6379656
    Abstract: A liquid composition used for dissolving fingernail polishes contains three non-miscible liquid phases which, when the composition is left still, are superimposed one on the other. The upper phase is oily. The intermediate phase is the solvent phase and contains solvents immiscible with water. In addition to a tri-phase composition also a bi-phase composition is described. The solvents are a mixture of methyl acetate and tert-butyl acetate.
