Abstract: Alkaline diamine track lubricants for use with glass, aluminum and two-piece PET containers and other articles of manufacture are prepared from an admixture of an alkyl diamine and a water-soluble hydrotrope. The diamine lubricants are prepared without the neutralization thereof and have a corrosion inhibitor which is, preferably, a reducing agent and a biocide incorporated thereinto. A source of alkalinity may be employed, as well, to maintain the pH above 8.

Abstract: A water soluble lubricant concentrate adapted to be admixed with water and a lubricant composition made therefrom which exhibit enhanced levels of lubricity and hard water stability and facilitate the transportation of containers on a conveyor. The concentrate and composition include:(a) an anionic surfactant selected from the group consisting of alpha olefin sulfonates, sulfonates of ethoxylated alcohols, alkyl aryl sulfonates, napthalene sulfonates and mixtures thereof;(b) a carrier for the anionic surfactant; and(c) a water soluble salt of aluminum selected from the group consisting of aluminum sulfate, aluminum nitrate, aluminum chloride, polyhydrates of potassium aluminum sulfate/aluminum sulfate complexes and mixtures thereof.
