Abstract
The current invention relates to a novel class of alkyl alcohol amines where the amine is a primary amine. Embodiments relate to a method of controlling microbial growth in metal working fluids, comprising adding such an alkyl alcohol amine to the metal working fluid. Other embodiments relate to semi-synthetic metal working fluid compositions which include the microbial growth control agent comprising this particular class of alkyl alcohol amines.
Claims15
A semi-synthetic metal working fluid, comprising:
- a. at least one base oil;
- b. at least one microbial growth control agent comprising an alkyl amine alcohol with the structure of:
- where R1 and R2 are H, or a C2 to C8 linear, branched or cyclic alkyl group, with the proviso that at least one of R1 and R2 is H and at least one of R1 and R2 is a C2 to C8 alkyl group;
- c. one or more organic acid;
- d. one or more emulsifiers;
- e. one or more concentrate additives;
- and
- f, water.
A composition suitable for use as a microbial growth control agent in a metalworking fluid comprising an alkyl amine alcohol with the structure of:
- where R1 and R2 are H, or a C2 to C8 linear, branched or cyclic alkyl group, with the proviso that at least one of R1 and R2 is H and at least one of R1 and R2 is a C2 to C8 alkyl group.
