Lubricant composition

Abstract

A lubricant composition is disclosed. The lubricant composition provides lubrication between metal parts, is able to clean metal parts and prevent build-up of contaminants within the lubricant composition. The lubricant composition includes a plurality of heptane aliphatic hydrocarbons, a non-heptane aliphatic hydrocarbon, a naphthenic petroleum base oil, an octadecenoic acid, and an ethoxylated alcohol. The plurality of heptane aliphatic hydrocarbons may include one-third branched heptanes, one-third cyclic heptanes, and one-third linear n-heptane. The non-heptane aliphatic hydrocarbon may be any aliphatic hydrocarbon with fewer than six carbon atoms that are not linked in a ring formation. The octadecenoic acid in the lubricant composition is generally 9-octadecenoic acid.

What is claimed is: 
     
         1 . A lubricating composition comprising:
 a non-heptane aliphatic hydrocarbon;   a plurality of heptane aliphatic hydrocarbons;   a naphthenic petroleum base oil;   an octadecenoic acid; and,   an ethoxylated alcohol.   
     
     
         2 . The lubricating composition of  claim 1  wherein the non-heptane aliphatic hydrocarbon comprises six or fewer carbon atoms. 
     
     
         3 . The lubricating composition of  claim 2  wherein the carbon atoms are not linked together to form a ring. 
     
     
         4 . The lubricating composition of  claim 3  wherein the non-heptane aliphatic hydrocarbon comprises one or more of ethane, ethene, butane, butene, propane, propene, methylpropane, pentane, hexane. 
     
     
         5 . The lubricating composition of  claim 1  wherein the non-heptane aliphatic hydrocarbon composes between about 60% and about 70% of the lubricating composition by weight. 
     
     
         6 . The lubricating composition of  claim 1  wherein the plurality of heptane aliphatic hydrocarbons comprises one or more of a branched heptane, a cyclic heptane, and a linear n-heptane. 
     
     
         7 . The lubricating composition of  claim 6  wherein the plurality of heptane aliphatic hydrocarbon comprises approximately one-third of one or more branched heptanes by weight, approximately one-third of one or more cyclic heptanes by weight, and one-third of linear n-heptane by weight. 
     
     
         8 . The lubricating composition of  claim 1  wherein the plurality of heptane aliphatic hydrocarbons composes between about 20% and about 30% of the lubricating composition by weight. 
     
     
         9 . The lubricating composition of  claim 1  wherein the octadecenoic acid is 9-octadecenoic acid. 
     
     
         10 . The lubricating composition of  claim 1  wherein the octadecenoic acid composes about 2% or less of the lubricating composition by weight. 
     
     
         11 . The lubricating composition of  claim 1  wherein the naphthenic petroleum base oil composes between about 5% and about 10% of the lubricating composition by weight. 
     
     
         12 . The lubricating composition of  claim 1  wherein the ethoxylated alcohol composes about 2% or less of the lubricating composition by weight.
