Concentrated solid and liquid antimicrobial lubricating compositions which include (-) about 1-20 wt % of a diamine acetate salt having the formula [(R1 )NH(R2)NH3]+(CH/COO) - or [(R1)NH2(R2)NH3++](CH3COO)2- wherein R1 is a C10-18 aliphatic group or an ether group having the formula R10O(R11) wherein R10 is a C10-18 aliphatic group and R11 is a C1-5 alkyl group; and R2 is a C1-5 alkylene group, (-) about 0-30 wt % of an alcohol for the purpose of enhancing the physical stability of the composition, and (-) about 0-20 wt % of a nonionic surfactant. The liquid form of the lubricant composition includes a major proportion of water while the solid form of the lubricant composition includes an amount of a solidification agent effective for assisting in solidification of the composition. The lubricating compositions are particularly useful on the load bearing surfaces of conveyor belts used in food preparation where a combination of effective lubricity and efficacious antimicrobial activity are necessary. |
