Abstract
Lubricating solutions are used on conveying systems in the beverage industry during the filling of containers with dairy products or other beverages. Lubricating compositions of the present invention, especially those designed for use in heavy load bearing conveyors such as those in the dairy industry conveying systems for contained beverages, comprise at least the following components:a) an alkyl alkoxylated (e.g., ethoxylated or propoxylated, preferably ethoxylated) phosphate ester,b) a secondary alcohol alkoxylate, (with an optional aryl [e.g., aromatic, such as phenol] alkoxylated [e.g., ethoxylated or propoxylated] phosphate ester),c) an aromatic or linear quaternary ammonium antimicrobial agent, andd) a liquid carrier, such as water.These lubricating solutions are capable of providing good lubricity and antimicrobial activity over a prolonged time and under high stress and heavy loads.
