(a) combining a mixture of components comprising:
component (a) which comprises at least one active foam control agent; and
component (b) which comprises at least one lubricating oil,
such that the amount of active foam control agent is from about 0.01 weight percent to about 70 weight percent, based upon total weight of said lubricating oil; and
(b) mixing (a) and (b) with sufficient energy to create a mixture, which does not show full liquid-liquid phase separation andor solid phase separation as determined by visual observation for at least 1 minute after mixing at ambient temperature.
2. The process of claim 2 wherein the lubricating oil is selected from the group consisting of fatty acid esters, fatty acid alkanol amides, mineral oils, polybutenes, polyalphaolefines, alkaline aromatics, polyglycols, fatty acid esterified polyglycols, and mixtures thereof.
3. The process of claim 3 wherein the active foam control agent is selected from the group consisting of acetylene diols and ethoxylated acetylene diols, silicone oils, modified siloxanes, polyglycols, esterified or modified polyglycols, fluorinated surfactants or chemicals, polyacrylates, fatty acids, fatty acid esters, fatty alcohols, fatty alcohol esters, waxes, ureum and mixtures thereof.
4. The process of claim 3 wherein the amount of foam control agent is from about 0.1 to about 5.0 parts, based upon the weight of the lubricating oil.
5. A stabilized foam control composition for lubricating compositions prepared in accordance with claims 1, 2, 3, or 4.
6. A lubricating composition comprising the foam control composition for a lubricating composition of claim 5 and a lubricating composition.
7. The lubricating composition of claim 6 wherein the amount of foam control agent for the lubricating composition is from about 0.1 to about 5 parts by weight based upon the total weight of the lubricating composition.
8. The foam control composition for a lubricating composition of claim 5, which is diluted with water.
9. The lubricating composition of claim 6, which is diluted with water.
10. The lubricating composition of claim 7, which is diluted with water.
11. The foam control composition for a lubricating composition of claim 7 wherein the amount of water in the diluted metal working fluid or lubricant is from 80 parts by weight to 99 parts by weight based upon the total weight of the diluted metal working fluid or lubricant.
12. The lubricating composition of claim 8 wherein the amount of water in the diluted metal working fluid or lubricant is from 80 parts by weight to 99 parts by weight based upon the total weight of the diluted metal working fluid or lubricant.
13. The lubricating composition of claim 9 wherein the amount of water in the diluted metal working fluid or lubricant is from 80 parts by weight to 99 parts by weight based upon the total weight of the diluted metal working fluid or lubricant.
The claims below are in addition to those above.
