Abstract
Fifty-nine monoethanolamines, diethanolamines and triethanolamines were studied for their antimicrobial properties in 13 cutting fluid products. It was found that 2-(N-amyl) ethanolamine exhibited outstanding activity in all of the products. Other compounds producing significant inhibition of microbial growth included N-methyl ethanolamine, N-ethyl ethanolamine, N-butyl ethanolamine, 2(N-methyl-N-heptyl) ethanolamine, 2-cyclo-hexyl ethanolamine, and N-benzyl ethanolamine.
