Abstract

A polish composition for metallic surfaces containing a polish and abrasive alumina nanoparticles in a water in oil emulsion composition composed of surfactants, suspending agents, and aluminum oxide particles of high purity of 200 nanometers or less having a median particle diameter of 0.24 microns together with an aliphatic hydrocarbon solvent producing a polish having cleaning properties and an enhanced high glossed surface from a single application.

Claims (12)

1. A metallic polish composition, comprising:

an oil soluble corrosion inhibitor in an amount of about 3.0 percent by weight based on the total weight of the composition;

a nonionic surfactant in an amount of about 3.0 percent by weight based on the total weight of the composition;

a stearic acid in an amount of about 8.3 percent by weight based on the total weight of the composition;

a hydrocarbon solvent comprising a middle distillate in an amount of about 27.7 percent by weight based on the total weight of the composition;

a chelating agent comprising a triethanolamine in an amount of about 3.8 percent by weight based on the total weight of the composition;

a calcined diatomaceous earth having a median particle size of about 5 microns in an amount of about 20.0 percent by weight based on the total weight of the composition;

an aluminum oxide having an average particle size of 20 nanometers and median particle diameter of 0.24 microns in an amount of about 1.0 percent by weight based on the total weight of the composition; and

water in an amount of about 33 percent by weight based on the total weight of the composition.

2. The metallic polish composition of claim 1 , further comprising colorants in an amount from 0.005 to 1.0 percent by weight based on the total weight of the composition.

3. The metallic polish composition of claim 1 , further comprising a fragrance in an amount from 0.001 to 1.0 percent by weight based on the total weight of the composition.

4. The metallic polish composition of claim 1 , further comprising a preservative in an amount from 0.05 to 1.0 percent by weight based on the total weight of the composition.
