Abstract
Abstract A low smoking lubricating composition for cold forming metal contains certain amounts of water, potassium nitrite, potassium soap of a chlorinated fatty acid, potassium soap of a sulfurized fatty acid, glycerine, defoaming agent and a block copolymer of ethylene oxide grafted on a polypropylene oxide which copolymer has a suitable molecular weight range and contains a sufficient amount of ethylene oxide to cause the composition to remain homogeneous between ambient temperature and the composition's boiling temperature.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
A normally liquid composition useful as a cold forming, metal working lubricant comprising: a. 45 to 200 parts by weight of water; b. 30 to 35 parts by weight of a block copolymer of ethylene oxide grafted on a polypropylene oxide which copolymer has both a molecular weight range and ethylene oxide content sufficient to cause the composition to remain homogeneous between ambient temperature and the boiling temperature of the composition; c. 1 to 15 parts by weight of a potassium soap of a sulfurized naturally occurring triglyceride containing from 5 to 25 weight percent sulfur; d. 1 to 10 parts by weight of a potassium soap of a chlorinated naturally occurring triglyceride containing from 25 to 50 weight percent chlorine; and e. 0.5 to 10 parts by weight of potassium nitrite.
