Abstract
Nail enamels of improved quality as regards settling, migration and flotation characteristics are provided by utilizing therein pigments coated with oxidized polyethylene.
Claims5
A nail enamel comprising at least one film-forming material, at least one plasticizer, at least one solvent for the film-forming material and plasticizer and at least one inorganic pigment, the inorganic pigment being one which has been coated with 1% to 10% by weight oxidized polyethylene to form an adsorbed coating on the pigment particles.
In a method of preparing nail enamel containing at least one film-forming material, at least one plasticizer, at least one solvent for the film-forming material and the plasticizer, and at least one inorganic pigment, the improvement comprising the step of dispersing an inorganic pigment having 1% to 10% by weight oxidized polyethylene adsorbed onto the surface of said inorganic pigment in the mixture of the film-forming material, plasticizer and solvent.
In a method of preparing nail enamel containing at least one film-forming material, at least one plasticizer, at least one solvent for the film-forming materials and the plasticizer, and at least one inorganic pigment selected from the group consisting of iron oxides, titanated mica, titanium dioxide, ultramarine, chromium oxide, chromium hydroxide and manganese violet, the improvement comprising the step of utilizing an inorganic pigment having a surface treatment of oxidized polyethylene and dispensing said coated pigment particles in a mixture of the film-forming material, plasticizer and solvent, the pigment being coated to have 1-10% by weight of oxidized polyethylene adsorbed on the surface of the pigment particles.
