Abstract
The present invention relates to an aqueous lubricating composition comprising at least: water, from 0.001% to 80% by weight of at least one polyalkylene glycol; and from 0.001% to 50% by weight of at least one alkoxylated, preferably ethoxylated, castor oil. The present invention also relates to the use of an aqueous lubricating composition as lubricant in a metalworking process, in particular for reducing, indeed even preventing, the formation of gummy residues.

1-10. (canceled)
An aqueous lubricant composition for metalworking comprising, based on a total weight of the composition:
- water;
- from 0.1% to 15% by weight of at least one polyalkylene glycol;
- and
- from 0.1% to 15% by weight of at least one alkoxylated castor oil.
A method of forming a metal part, comprising:
- applying an aqueous lubricant composition to a metal workpiece and/or a machining tool;
- and
- machining the metal workpiece using machining apparatus to form a metal part, such that the aqueous lubricant composition reduces friction during the machining,
- wherein the aqueous lubricant composition comprises, based on a total weight of the composition:
- water;
- from 0.1% to 15% by weight of at least one polyalkylene glycol;
- and
- from 0.1% to 15% by weight of at least one alkoxylated castor oil.
