Abstract

A lubricant composition with improved stability and tolerance for water hardness comprises a synthetic wax emulsion; an amine derivative; an emulsifier; and a sequestrant. The synthetic wax emulsion may include poly(ethyleneoxide)-based or poly(propyleneoxide)-based wax emulsions. The amine derivative may include alkyl C 12 -C 14 oxy propyl diamine. The lubricant composition can be used for lubricating the passage of a container along a conveyor. The method includes applying the lubricant composition to at least a part of the container or the conveyor in an application cycle, where the application cycle includes a first period of time of dispensing the lubricant composition and a second period of time of not dispensing the lubricant composition.

First claim

What is claimed is:

1. A lubricant composition comprising:
a natural wax emulsion;
an amine or amine derivative selected from the group consisting of fatty amines, ether amines or salts thereof, oleyl diaminoalkane, oleyl diaminopropane, alkyl C 12 -C 14 oxy propyl diamine or coco diaminopropane, lauryl propyl diamine, dimethyl lauryl amine, PEG coco amine, and combinations thereof;
an emulsifier, wherein the emulsifier is present at about 0.1 wt. % to about 5 wt. % of the lubricant composition; and
a sequestrant.

2. The lubricant comprising of claim 1 , wherein the natural wax emulsion comprises a natural wax selected from the group consisting of carnauba wax, candelilla wax, cotton seed wax, bayberry wax, myrtle wax, palm kernel wax, Japan wax, animal wax, beeswax, Chinese wax, lanolin, tallow-based wax, and combinations thereof.

3. The lubricant composition of claim 1 , wherein the emulsifier comprises an anionic surfactant.

4. The lubricant composition of claim 1 , wherein the sequestrant comprises a phosphate.

5. The lubricant composition of claim 1 , wherein the sequestrant is present at about 0.01 wt. % to about 1 wt. % of the lubricant composition.

6. The lubricant composition of claim 1 , wherein the lubricant composition comprises from about 0.5 wt. % to about 20 wt. % of the amine or amine derivative.

7. The lubricant composition of claim 1 , wherein the natural wax and the amine or amine derivative are present at a ratio of from about 2 to about 20 parts natural wax for every 1 part of amine or amine derivative.

8. The lubricant composition of claim 1 , further comprising a synthetic wax.

9. The lubricant composition of claim 1 , wherein the amine or amine derivative is a diaminoalkane or derivative thereof.

10. The lubricant composition of claim 1 , wherein the amine or amine derivative comprises alkyl C12-C14 oxypropyl diamine.

11. The lubricant composition of claim 1 , wherein the lubricant composition is a concentrate that is diluted with water.

12. The lubricant composition of claim 1 , further comprising quaternary ammonium compounds, isothiazolinone, or guanidine.

13. The lubricant composition of claim 1 , further comprising a nonionic surfactant.

14. The lubricant composition of claim 1 , wherein the sequestrant comprises aluminosilicates, nitroloacetates, aminocarboxylates, EDTA, HEDTA, TSPP, TKPP, PAA, phosphonobutane carboxylic acid, sodium gluconate, tetrasodium pyrophosphate, or combinations thereof.

15. The lubricant composition of claim 1 , further comprising hydrophilic diluents, antimicrobial agents, stabilizing agents, coupling agents, detergents and dispersing agents, anti-wear agents, viscosity modifiers, corrosion inhibitors, film forming materials, antioxidants, antistatic agents, or combinations thereof.
