Lower risk is also obtained by addition of a thixotropic thickener to the petroleum distillate based product, to provide a product having a viscosity of greater than 100 SUS at rest at 100° F., but which exhibits shear-thinning, so as to be capable of being dispensed as a spray or fine mist by a non-pressurized spray dispenser or pump. Still further risk lowering may be attained by the addition of an effective amount of a bittering or aversion agent so as to substantially discourage voluntary ingestion of the petroleum distillate based product.

    Abstract: A thickened nail polish remover includes a solvent/water blend containing a major amount of organic solvent and a minor amount of water. The nail polish remover also includes a water-wetted thickener that, when dry, is readily dispersible in water but not readily dispersible in the solvent/water blend. The nail polish remover further includes a long chain amine neutralizing agent. The thickened nail polish remover has a viscosity of from 3,000 centipoise to 90,000 centipoise at 21.degree. C. In one embodiment, the thickened nail polish remover is formulated to be easily rinsable from the nails with water, by selecting a long chain amine neutralizing agent so that the neutralized thickener is compatible both with the solvent/water blend and with the water used to rinse the nails. In the method of preparing the thickened nail polish remover, the thickener is prewetted with the water of the solvent/water blend to form a dispersion of the thickener in the water.

  • Patent number: 5985807
    Abstract: The use of an organopolysiloxane of elastomeric nature used in combination with an organic phase for the preparation of a composition and/or in a composition for removing make-up from the nails, in particular by a solvent for nail varnish. The organic phase comprises at least one organic solvent or at least one mixture of cosmetic organic solvents capable of dissolving a nail varnish and having Hansen's mean solubility parameters dD, dP and dH which satisfy the following three conditions:(1) dD.ltoreq.20 (J/cm.sup.3).sup.1/2(2) dP.ltoreq.10 (J/cm.sup.3).sup.1/2(3) dH.ltoreq.15 (J/cm.sup.3).sup.1/2The products for the removal of make-up from the nails, according to the invention, can give the latter, after use, a lasting soft feel without spoiling them. They are capable of not producing phenomena of drying out of the nail, nail whitening or losses in nail gloss after removal of make-up.

  • Patent number: 5961731
    Abstract: A method for removing a scuff mark from a shoe surface made from a synthetic material comprises the steps of: applying a fingernail polish remover composition to the shoe surface with a cotton ball; rubbing the composition into the surface; and removing the scuff mark and the composition from the surface. The composition may consist essentially of acetone; water; glycerin; diglycerol; and gelatin. The composition may alternately consist essentially of ethyl acetate; isopropyl alcohol; water; benzophenone 1; isopropyl myristate; butyl acetate; and mineral salts containing sodium, potassium, magnesium, calcium, chloride, bromide, iodide, sulfate, and carbonate. Still further, the composition may alternately consist essentially of other nail polish remover compositions.

  • Patent number: 5866104
    Abstract: A nail polish remover comprises about 25 to 95% glycol ether ester and about 5 to 75% glycol ether. The remover preferably comprises about 5 to 40% water. The remover is highly effective and yet is gentle to the nails and skin and relatively hazard-free. The remover is free of acetone and ethyl acetate, the two most widely used and hazardous solvents in current commercial nail polish removers.
