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.
Claims15
A synthetic diamine-based track lubricant, comprising:
- (a) an alkyl diamine,
- (b) a water-soluble hydrotrope selected from the group consisting of ethoxylated alkyl amines, having at least 6 carbon atoms in the alkyl portion, nonionic surfactants and mixtures thereof,
- (c) a source of alkalinity,
- (d) a corrosion inhibitor,
- (e) water, and
- wherein the lubricant has a pH greater than 8 and the diamine is not neutralized.
