Abstract
Abstract A conveyor cleaner-lubricant concentrate is derived from a concentrate of C 12 to C 18 alpha olefin sulfonate, and water or a water-soluble solvent. The sulfonate concentrate can be directly diluted with water to form a cleaner-lubricant. Alternatively, the sulfonate can be directly added to soap lubricants. The sulfonate-based lubricants are acid resistant and exhibit excellent lubricating and cleaning properties.
