         3 . The belt lubricant concentrate according to  claim 1 , wherein the alkyl group of the at least one N-alkyl-1,3-propanediamine is a C 10 -C 24  alkyl group, a C 12 -C 22  alkyl group, a C 14 -C 20  alkyl group, a C 16 -C 20  alkyl group, or a C 18  alkyl group. 
     
     
         4 . The belt lubricant concentrate according to  claim 1 , wherein the at least one N-alkyl-1,3-propanediamine is N-octadecyl-propane-1,3-diamine. 
     
     
         5 . The belt lubricant concentrate according to  claim 1 , wherein the at least one nonionic surfactant is a polyalkylene glycol ether. 
     
     
         6 . The belt lubricant concentrate according to  claim 5 , wherein the polyalkylene glycol ether has a degree of ethoxylation of 15 to 30. 
     
     
         7 . The belt lubricant concentrate according to  claim 1 , wherein the concentrate comprises 18% by weight to 28% by weight of the at least one monocarboxylic acid. 
     
     
         8 . The belt lubricant concentrate according to  claim 1 , wherein the concentrate comprises 12% by weight to 22% by weight of the at least one N-alkyl-1,3-propanediamine. 
     
     
         9 . The belt lubricant concentrate according to  claim 1 , wherein the concentrate comprises 5% by weight to 12% by weight of the at least one nonionic surfactant. 
     
     
         10 . The belt lubricant concentrate according to  claim 1 , wherein the concentrate further comprises 10% by weight to 30% by weight of at least one alcohol and/or 5% by weight to 10% by weight of at least one glycol ether. 
     
     
         11 . The belt lubricant concentrate according to  claim 1 , wherein the water is substantially deionized. 
     
     
         12 . A belt lubricant comprising 0.01% by weight to 0.1% by weight of the belt lubricant concentrate according to  claim 1  and lubricant water up to 100% by weight. 
     
     
         13 . The belt lubricant according to  claim 12 , wherein the belt lubricant comprises 0.02% by weight to 0.09% by weight of the belt lubricant concentrate. 
     
     
         14 . The belt lubricant according to  claim 12 , wherein the lubricant water is substantially deionized. 
     
     
         15 . The belt lubricant according to  claim 12 , wherein the belt lubricant comprises 0.01 mg/L to 1 mg/L of chlorine dioxide. 
     
     
         16 . A method of lubricating a chain and/or belt lubrication system in the food industry, comprising supplying the belt lubricant concentrate according to  claim 1  to the chain and/or belt lubrication system. 
     
     
         17 . A method of lubricating the travel of a container along a conveyor belt, comprising applying the belt lubricant according to  claim 12  to the conveyor belt. 
     
     
         18 . The method according to  claim 17 , further comprising bringing the conveyor belt into contact with process water which comprises 0.01 mg/L to 1 mg/L of chlorine dioxide.
