Definitions

  • the present invention relates to a nail cosmetic - in particular, a water- based, nail product that can be removed by peeling without the use of an acetone- based nail lacquer remover. Additionally, the present invention relates to a cosmetic product that can deliver water-soluble active ingredients to the nail.
  • Nail lacquers are cosmetic formulations that coat the nails.
  • nail lacquers are mixtures of film-forming polymers, plasticizers, as well as colorants and other additives dissolved in a mixture of volatile organic solvents.
  • Consumer selection of nail cosmetics is influenced by a number of factors, for example, color (both in bottle and on nails), gloss, opacity, and durability (of color and gloss as well as resistance to chipping).
  • Performance and aesthetic attributes are not, however, the only determinants of consumer choice. Purchasers of nail cosmetics are also strongly influenced by ease of application, including dry time, and removal.
  • the basecoat of the water-based nail cosmetic system of the present invention has a comparatively faster dry time vis-a-vis a conventional nail lacquer. This attribute allows users to apply a second, and as needed third, basecoat ⁇ i.e. , after the previous coat has dried) in substantially less time than is required to apply a similar number of coats of a conventional nail lacquer.
  • Acetone-based formulations are widely used to remove the majority of nail lacquers. Because nail lacquer removers need to dissolve and remove multiple layers of lacquer, removers typically contain at least about seventy percent acetone. It is well-known, however, that acetone removers have a several significant negative properties - (i) they emit what many users consider to be an unpleasant (even noxious) odor; (ii) some have suggested that acetone poses potential health hazards; (iii) acetone has a significant drying effect on nails and skin; (iv) when acetone dissolves conventional nail lacquers, especially reds and darker colors, the skin is often stained.
