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.

Water based semi-synthetic metal working fluid composition containing an alkyl alcohol amine

The present invention describes a water based semi-synthetic metal working fluid comprising a base oil, an organic acid, emulsifiers, optionally a concentrate additive, water and a microbial growth control agent which comprises a glycol ether amine.

Water based semi-synthetic metalworking fluid composition

A microbial growth control agent and method of controlling microbial growth in metal working fluids, wherein the agent comprises at least a glycol ether amine.

Metal working fluids biocide

Disclosed herein are apparatuses comprising, for example, a microfluidic channel device comprising a main body comprising a channel configured to provide for helical fluid motion of material within the channel; and a temperature control system that applies a temperature gradient to the channel. Methods of making and using the apparatus are also described.
