Lubricant composition, method of preparing the same, and firearm cleaner including the same

A method of manufacturing a lubricant composition, the method comprising:

• contacting
• 0.01 to 1 weight percent of tungsten disulfide having a particle size of 4 to 160 nanometers,
• a borate ester, wherein the borate ester comprises a reaction product of a fatty oil, a C2 to C10 dialkanolamine, and boric acid, and a borate ester selected from trimethyl borate, triethyl borate, tri-n-propyl borate, tri-n-butyl borate, triisopropyl borate, tri-t-amyl borate, triphenyl borate, trimethoxy boroxine, tri-2-cyclohexylcyclohexyl borate, a trialkanolamine borate, manittol borate, glycerol borate, or a combination thereof,
• an anti-scuff agent comprising a metal dithiophosphate, a metal dithiocarbamate, a metal dialkyldithiophosphate, a metal dialkyldithiocarbamate, or a combination thereof,
• an organic tungsten composition,
• a polyalphaolefin, and
• a base oil under conditions effective to disperse the tungsten disulfide, the borate ester, the organic tungsten composition, the anti-scuff agent, and the polyalphaolefin in the base oil to manufacture the lubricant composition.

A lubricant composition comprising:

• 0.01 to 1 weight percent tungsten disulfide comprising tungsten disulfide particles having a diameter of 4 to 80 nm;
• a borate ester, wherein the borate ester comprises a reaction product of a fatty oil, a C2 to C10 dialkanolamine, and boric acid, and a borate ester selected from trimethyl borate, triethyl borate, tri-n-propyl borate, tri-n-butyl borate, triisopropyl borate, tri-t-amyl borate, triphenyl borate, trimethoxy boroxine, tri-2-cyclohexylcyclohexyl borate, a trialkanolamine borate, manittol borate, glycerol borate, or a combination thereof;
• an anti-scuff agent comprising a metal dithiophosphate, a metal dithiocarbamate, a metal dialkyldithiophosphate, a metal dialkyldithiocarbamate, or a combination thereof;
• a polyalphaolefin;
• and
• a base oil.
