Abstract: The application of a soluble calcium compound and the further application of a suitable fluoride material accomplish calcium remineralization of fingernails. The calcium and fluoride preparations are kept separate until used. The calcium preparation is rubbed into the nail prior to the application of the fluoride; the fluoride then combines with the calcium applied in the first step within the nail allowing the nail to become harder and stronger.

Abstract: Metallic fluoride salts characterized by a water solubility of 0.05 to 2.00 grams of fluoride per 100 grams of water and an organic solvent solubility of less than 0.10 grams of solid per 100 grams of solvent are added to colored or clear finger nail enamel compositions to provide nail enamels which are unaltered in color rendition, exhibit excellent adhesion to finger nails and, when applied to finger nails, exhibit substantially increased duration of wear.

Abstract: A non-aqueous organic composition for hardening and strengthening fingernails and toenails of human beings comprises a cosmetically acceptable organic vehicle containing a nail strengthening agent in the form of ammonium hexafluorophosphate dissolvable in this vehicle and providing an effective amount of fluoride.

Abstract: Various surfaces are polished by buffing with compositions comprising a foamed polymeric material and a finely divided abrasive material. The abrasive material has a particle size number and a valley abrasion number the product of which falls within a predetermined range sufficient to provide good polishing upon buffing. Such compositions can be fashioned into articles of manufacture which are capable of buffing various surfaces.

Abstract: A safety enclosure comprises a hollow thin flexible insulator having a vertical rectangular front panel with top and bottom horizontal edges and oppositely disposed vertical side edges. The insulator has top and bottom walls and oppositely disposed side walls. The top wall is integral with the panel and extends rearwardly and upwardly from the top edge. The bottom wall is integral with the panel and extends rearwardly and downwardly from the bottom edge. Each side wall is integral with the top and bottom walls and the panel and extends rearwardly and outwardly from the panel. The panel has a central opening. Each side wall has upper and lower horizontal elongated slots completely spanning the side wall and disposed respectively slightly above and slightly below said opening. The upper and lower slots of one side wall are horizontally aligned with the upper and lower slots respectively of the other side wall.
