Abstract
A nail-and-cuticle conditioning emery board comprising a thin solid support strip having at least one abrasive surface adhesively attached to the support strip, and a thin film of a nail conditioning composition made up of a lubricant polyethylene glycol and a humectant polyethylene glycol, or absorbent emollient containing polymeric powder particles which are adhesively fixed to the abrasive surface. The use of the emery board results in conditioning of the fingernails and cuticles while filing them.
Claims12
A nail- and cuticle-conditioning emery board comprising:
- a thin solid support strip having at least one abrasive surface adhesively attached onto said support, said abrasive surface comprising a substrate layer and abrasive particles adhesively fixed on said substrate and
- a nail-conditioning composition on said abrasive surface, said composition being selected from the group consisting of:
- (a) a uniform film comprising a lubricant polyethylene glycol having a molecular weight between about 1000 and about 13,750 and a humectant polyethylene glycol having a molecular weight between about 150 and about 600, said film being sufficiently thin so as not to impart a greasy feeling to the touch and not to interfere with the abrasive action of said emery board;
- and
- (b) a layer of absorbent polymeric powder particles fixed on said abrasive surface having an emollient entrapped therein, said emollient being suitable for conditioning nails and being releasable from said polymeric powder upon the application of such pressure on said particles as is normally applied during filing fingernails.
