权利要求: 1. A semi-synthetic metal working fluid, comprising:a. at least one base oil;b. at least one microbial growth control agent comprising a glycol ether amine with the structure of: wherein R1 is a C1-C6 alkyl group and R2 is CH3 or CH2—CH3 and R3 is CH3 or CH2—CH3, and m is 0 to 6;c. one or more organic acids,d. one or more emulsifiers,e. optionally, one or more additives, andf. water.2. The semi-synthetic metal working fluid of claim 1, wherein R1 of the microbial growth control agent is a C3-C4 alkyl group.3. The semi-synthetic metal working fluid of claim 1, wherein the glycol ether amine is selected from the group consisting of 2-butoxy-ethanamine, 1-methoxy-2-propanamine, 1-butoxy-2-propanamine, 1-[1-methyl-2-(1-methyl-2-propoxyethoxy)ethoxy]-2-propanamine1-(2-butoxy-1-methylethoxy)-2-propanamine, 1-(2-methoxy-1-methylethoxy)-2-propanamine or 1-(1-methyl-2-propoxyethoxy)-2-propanamine.4. The semi-synthetic metal working fluid of claim 1, wherein the microbial growth control agent further comprises another amine.5. The semi-synthetic metal working fluid of claim 1, wherein m is from 0 to 2 in the microbial growth control agent.6. The semi-synthetic metal working fluid of claim 1, wherein the base oil is selected from naphthenic oils, paraffinic oils, ester oils and mixtures thereof.7. The semi-synthetic metal working fluid of claim 1, wherein the emulsifier is selected from C16-C18 alcohols which have been ethoxylated or propoxylated, ethoxylated C12-C15 alcohols, sodium alkane sulfonate and alky ether carboxylates and mixtures thereof.8. The semi-synthetic metal working fluid of claim 1, wherein the solubilizer is selected from ethylhexoic acid, azelaic acid, toll oil fatty acid, 12-hydoxyl-(cis)-9-octadecenoic acid, dicarboxylic acid, 9-octadecenoic acid and mixtures thereof.9. The semi-synthetic metal working fluid of claim 1, wherein the additive is present and is selected from diethylene glycol butyl ether, ethylene glycol monobutyl ether, propylene glycol butyl ether and mixtures thereof.10. The semi-synthetic metal working fluid of claim 1, wherein the microbial growth control agent is present in an amount of from 6 to 15 percent by weight of the semi-synthetic metal working fluid.11. The semi-synthetic metal working fluid of claim 1, wherein the base oil is present in an amount of from 10 to 45 percent by weight of the semi-synthetic metal working fluid.12. The semi-synthetic metal working fluid of claim 1, wherein the emulsifier is present in an amount of from 5 to 20 percent by weight of the semi-synthetic metal working fluid.13. The semi-synthetic metal working fluid of claim 1, wherein the solubilizer is present in an amount of from 3 to 10 percent by weight of the semi-synthetic metal working fluid.14. The semi-synthetic metal working fluid of claim 1, wherein the water is present in an amount of from 20 to 60 percent by weight of the semi-synthetic metal working fluid.
