  "claims": [
    "1. An aqueous conveyor lubricant composition concentrate consisting essentially of: (a) a carrier selected from the group consisting of water, alkanols, a polyhydric alcohol; and mixtures thereof; and (b) a first solubilizing agent consisting essentially of an alkyl tertiary amine having between 8 and 10 carbon atoms; and (c) a fatty acid selected from the group consisting of C12 to C22 saturated and unsaturated carboxylic acids and mixtures thereof; (d) a second solubilizing agent selected from the group consisting of alkyl aryl sulfonates; and (e) a harness sequestering agent.",
    "2. The conveyor lubricant of claim 1 wherein the alkanol is selected from the group consisting of: ethanol, propanol, butanol, ethylene glycol, propylene glycol, and diethylene glycol, and mixtures thereof.",
    "3. The aqueous conveyor lubricant of claim 1 wherein: (a) the carrier is present in an amount from about 30 parts and about 75 parts by weight based on total concentrate weight; (b) the a tertiary alkyl amine solubilizing agent is present in an amount from between about 2 parts to about 10 parts by weight of total concentrate weight; and (c) the fatty acid is present in an amount of between about 0.5 parts to about 15 parts by weight based on total concentrate weight.",
    "4. The aqueous conveyor lubricant of claim 3 wherein the tertiary alkyl amine solubilizing agent is selected from the group consisting of: decyl dimethyl amine, dimethyl octyl amine, and mixtures thereof.",
    "5. The aqueous conveyor lubricant concentrate of Claim 4 wherein the fatty acid is a mixture of saturated and unsaturated fatty acids wherein the fatty acids are selected from the group consisting of: oleic, linoleic, linolenic, lauric, myristic, palmetic and coconut oil fatty acids and mixtures thereof.",
    "6. The aqueous conveyor lubricant concentrate of claim 1 wherein the hardness sequestering agent is selected from the group consisting of: the alkali metal salts of ethylene diamine tetraacetic acid (EDTA), gluconic acid, phosphonic acid, or nitrilotriacetic acid (NTA).",
    "7. The aqueous conveyor lubricant concentrate of Claim 9 wherein the sequestrant is present in an amount of between about 2 parts to about 15 parts by weight based on total weight of the concentrate.",
    "8. The aqueous conveyor lubricant concentrate of claim 4 wherein the a tertiary alkyl amine solubilizing agent is N,N-dimethyl octyl amine.",
    "9. The aqueous conveyor lubricant concentrate of claim 5 wherein the fatty acid composition is a mixture of coconut oil fatty acid and oleic acid.",
    "10. The aqueous conveyor lubricant concentrate of claim 1 wherein the alkyl aryl sulfonate is diphenyl disulfonate.",
    "11. The aqueous conveyor lubricant concentrate of claim 6, wherein the sequestrant is NaEDTA.",
    "12. An aqueous conveyor lubricant concentrate composition comprising: (a) water present in an amount of between about 30 parts and about 75 parts by weight based on total concentrate weight; and (b) N,N-dimethyl octyl amine present in an amount between about 2 parts to about 10 parts by weight of the total weight of concentrate; and (c) a fatty acid mixture of coconut oil fatty acid present in an amount between about 0.25 parts and about 7 parts by weight based on total concentrate weight and oleic acid present in an amount between about 0.25 parts and about 7 parts by weight based on total concentrate weight; (d) diphenyl disulfonate present in an amount between about 10 parts and about 30 parts by weight based on total weight of concentrate; (e) the sodium salt ethylene diamine tetraacetic acid as a hardness sequestering agent present in an amount between about 2 parts and about 15 parts by weight based on total concentrate weight.",
    "13. A process for forming an aqueous conveyor lubricant concentrate composition comprising the following steps: (a) heating a carrier in an amount between about 43 parts and about 62 parts by weight of total concentrate together with an alkyl aryl sulfonate present in an amount between 10 parts and about 30 parts by weight total concentrate to a temperature of 120° F.; and (b) adding to the carrier-sulfonate solution a hardness sequestering agent present in an amount between 1 part and 5 parts by weight total concentrate; and (c) adding to the solution an alkyl a tertiary amine present in an amount between 2 parts and about 10 parts by weight based on total concentrate; and (d) admixing therewith fatty acid present in an amount between about 0.5 to about 15 percent by weight; and (e) heating the total mixture with stirring to a temperature of 120° F. until a homogenous solution is formed.",
    "14. The process of claim 14 wherein the carrier is water.",
    "15. The process of claim 13 wherein the alkyl aryl sulfonate is a diphenyl disulfonate.",
    "16. The process of claim 13 wherein the hardness sequestering agent is NaEDTA.",
    "17. The process of claim 13 wherein the a tertiary alkyl amine is dimethyl octyl amine.",
    "18. The process of claim 13 wherein the fatty acid comprises a mixture of fatty acids selected from the group consisting of lauric, myristic, palmetic, coconut oil fatty acid and oleic, linoleic, and linolenic acids and mixtures thereof.",
    "19. The process of claim 13 wherein the fatty acid is present in an amount between 0.5 parts and about 15 parts by weight per total concentrate weight.",
    "20. The fatty acid mixture of claim 13 wherein the fatty acid comprises a mixture of oleic acid and coconut oil fatty acid.",
    "21. The fatty acid mixture of claim 13 wherein the oleic acid is present in an amount between about 0.25 parts and about 7 parts by weight of total concentrate weight and the coconut oil fatty acid is present in an amount between 0.25 parts and 7 parts by weight of total concentrate weight.",
