Abstract

An aqueous non-toxic biorational or environmentally safe composition to reduce or inhibit corrosion, rust and scale on metal surfaces comprising effective amounts of sorbic acid, salts of sorbic acid and/or derivatives thereof and a variety of hydrocarbons, esters, acids, alcohols and/or saponified fatty acids or combinations thereof derived from beeswax, vegetable waxes and/or derivatives thereof.

Claims (17)

1. An aqueous non-toxic environmentally safe composition to reduce or inhibit corrosion, rust and scale on metal surfaces comprising effective amounts of sorbic acid, salts of sorbic acid and/or derivatives thereof and at least one wax selected from the group consisting of hydrocarbons, esters, acids, alcohols and/or saponified fatty acids and combinations thereof, wherein said effective amounts include from about 0.004 percent beeswax to about 0.40 percent beeswax, from about 0.30 percent potassium sorbate to about 3.50 percent potassium sorbate with the balance purified water, all by weight.

2. An aqueous non-toxic environmentally safe composition to reduce or inhibit corrosion, rust and scale on metal surfaces as a flash rust inhibitor comprising effective amounts of sorbic acid, salts of sorbic acid and/or derivatives thereof and at least one wax selected from the group consisting of hydrocarbons, esters, acids, alcohols and/or saponified fatty acids and combinations thereof, wherein said effective amounts include from about 0.004 percent beeswax to about 0.01 percent beeswax, from about 0.30 per cent potassium sorbate to about 0.35 percent potassium sorbate, with the balance purified water, all by weight.

3. An aqueous non-toxic environmentally safe composition to reduce or inhibit corrosion, rust and scale on metal surfaces as a bath or dip comprising effective amounts of sorbic acid, salts of sorbic acid and/or derivatives thereof and at least one wax selected from the group consisting of hydrocarbons, esters, acids, alcohols and/or saponified fatty acids and combinations thereof, wherein said effective amounts includes from about 0.02 percent beeswax to about 0.1 percent beeswax, from about 2.50 percent potassium sorbate to about 3.50 percent potassium sorbate, with the balance purified water, all by weight, having a pH of about 8.0 to about 9.0 and conductivity of from about 14.20 ms/cm to about 16.20 ms/cm.

4. The aqueous non-toxic environmentally safe composition to reduce or inhibit corrosion, rust and scale on metal surfaces as a paint preservative or additive comprising effective amounts of sorbic acid, salts or sorbic acid and/or derivatives thereof and at least one wax selected from the group consisting of hydrocarbons, esters, acids, alcohols and/or saponified fatty acids and combinations thereof, wherein said effective amounts includes from about 0.30 percent beeswax to about 0.40 percent beeswax and from about 17.00 percent potassium sorbate to about 25.00 percent potassium sorbate, with the balance purified water, all by weight having a pH of about 7.0 to about 10.0 and a conductivity of from about 60 ms/cm to about 80 ms/cm.

5. The aqueous non-toxic environmentally safe composition of claim 1 wherein said effective amounts include about 0.007 percent beeswax, about 0.325 percent potassium sorbate with the balance purified water, all by weight.

6. The aqueous non-toxic environmentally safe composition of claim 5 further includes about 0.000076 percent surfactant when used as a flash rust inhibitor.

7. The aqueous non-toxic environmentally safe composition of claim 1 further includes from about 0.00007 percent surfactant to about 2.0 percent surfactant and from about 0.009 percent fiber to about 0.013 percent fiber to stabilize said composition for uniform or homogeneous component distribution within said composition, all by weight.

8. The aqueous non-toxic environmentally safe composition of claim 1 wherein said composition forms a layer less than about 350 nanometers in thickness.

9. The aqueous non-toxic environmentally safe composition of claim 2 wherein said effective amounts include about 0.007 percent beeswax, about 0.325 percent potassium sorbate with the balance purified water, all weight.

10. The aqueous non-toxic environmentally safe composition of claim 9 wherein said composition includes a pH of about 8.5.

11. The aqueous non-toxic environmentally safe composition of claim 10 wherein said composition includes conductivity of about 2.00 ms/cm.

12. The aqueous non-toxic environmentally safe composition of claim 9 wherein said composition includes a pH of from about 7.0 to about 10.0.

13. The aqueous non-toxic environmentally safe composition of claim 12 wherein said composition includes conductivity is from about 1.70 ms/cm to about 2.30 ms/cm.

14. The aqueous non-toxic environmentally safe composition of claim 2 wherein said composition forms a layer less than about 350 nanometers in thickness.

15. The aqueous non-toxic environmentally safe composition of claim 3 wherein said effective amounts includes about 062 percent beeswax and about 2.957 percent potassium sorbate with the balance purified water, all by weight.

16. The aqueous non-toxic environmentally safe composition of claim 3 wherein said composition includes a pH of about 8.5.

17. The aqueous non-toxic environmentally safe composition of claim 4 wherein composition forms a layer less than about 350 nanometers in thickness.
