权利要求: 1. A metal working fluid composition comprising a microbial growth control agent suitable for metal working fluids, comprising 2-butoxy-ethanamine, or at least one glycol ether amine with the structure of:wherein R1 is a C3-C4 alkyl group and R2 is CH3 or CH2-CH3 and R3 is CH3 or CH2-CH3, and m is 0 to 6;wherein the metal working fluid composition further comprises:water; mineral oil; and emulsifier; and wherein the glycol ether amine is present in an amount of from 5% to 20% by weight of the metal working fluid.2. The metal working fluid composition of claim 1, wherein R1 is a C3-C4 alkyl group or m is 0 to 2.3. The metal working fluid composition of claim 1, wherein the at least one glycol ether amine 1-methoxy-2-propanamine, 1-butoxy-2-propanamine, 1-[1-methyl-2-(1-methyl-2-propoxyethoxy)ethoxy]-2-propanamine′1-(2-butoxy-1-methylethoxy)-2-propanamine, 1-(2-methoxy-1-methylethoxy)-2-propanamine or 1-(1-methyl-2-propoxyethoxy)-2-propanamine.4. The metal working fluid composition of claim 1, wherein the metal working fluid compositions comprises one or more other functional additives selected from the group consisting of lubricants, corrosion inhibitors, solubilizers, pH neutralizers and biocides.5. The metal working fluid composition of claim 1, wherein the metal working fluid composition further comprises a second glycol ether amine.6. A method of controlling microbial growth in metal working fluids by use of from 5 to 20% by weight of a microbial control agent, wherein the microbial control agent comprises one glycol ether amine with the structure of:wherein R1 is a C3-C4 alkyl group and R2 is CH3 or CH2-CH3 and R3 is CH3 or CH2-CH3, and m is 0 to 6 wherein the metal working fluids further comprise: water; mineral oil; and emulsifier.7. The method of claim 6, wherein at least one other glycol ether amine is used.8. The method of claim 6, wherein the method is used for controlling bacteria, mold, or yeast in metal working fluids.
