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.

Alkaline diamine track lubricants

Stress cracking in poly(alkylene terephthalate) articles of manufacture is prevented by applying to the article a hydrophilic-substituted aromatic hydrocarbon having either an alkyl or aryl side chain, such as, sodium xylene sulfonate. Preferably, the stress crack inhibitor is applied to the article in the form of an aqueous fatty acid-based lubricant.

Compositions for preventing stress cracks in poly(alkylene

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:
