Abstract
Stable concentrated liquid and solid antimicrobial lubricating compositions can be formulated which include (-) 5 to 40 wt % of a C.sub.6-24 fatty acid, (-) 10 to 40 wt % of a quaternary ammonium salt, (-) an amount of an alkaline source sufficient to increase the pH of the composition to at least 8, and optionally (-) about 0.1 to 10 wt % of an amine. The balance of the liquid form of the composition constitutes water. 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.
