Abstract

Abstract A fingernail refinishing product and method for dissolving and removing old lacquer nail polish, for softening and conditioning fingernails, cuticles and surrounding skin, and for depositing a clear nail-strengthening priming coat, all simultaneously, in preparation for the application of fresh nail polish. The product comprises a spill-proof applicator in the form of a reclosable container filled with a slitted sponge saturated with a water-miscible liquid composition which contains solvents, film-forming and nail-strengthening ingredients, and substantial amounts (up to 25% by weight) of an emollient-emulsifier-cleaner formed by the sulfonation reaction of the ricinoleic acid in castor oil. The three-function fingertip treatment--polish removal, conditioning, and nail prime-coating--takes place inside the applicator and is accomplished by the insertion of each fingertip, at least one at a time, into contact with the liquid saturated sponge.
