Abstract

A processing fluid that is free of boron and secondary amines includes a petroleum-based or non-petroleum-based oil; water; and an additive composition comprising a long chain primary amine; an tertiary cycloalkylamine; and an amino acid.

Claims

1. An additive composition comprising:

a long chain primary amine;

a tertiary cycloalkylamine; and

an amino acid;

wherein the additive composition is boron-free and free of a secondary amine.

2. The additive composition of claim 1, wherein the long chain primary amine is a C₈-C₂₄ primary amine.

3. The additive composition of claim 1, wherein the tertiary cycloalkylamine is an ethoxylated tertiary cycloalkylamine selected from the group comprising di(ethanol)cyclopentylamine, di(ethanol)cyclohexylamine, di(ethanol)cycloheptylamine, dicyclopentyl(ethanol)amine, and/or dicyclohexyl(ethanol)amine.

4. The additive composition of claim 1, wherein the amino acid is of the formula NH₂CHR²CO₂H, wherein R² is H or alkyl.

5. The additive composition of claim 1, wherein the amino acid is alanine, arginine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, histidine, isoleucine, leucine, lysine, methionine, phenyalanine, serine, threonine, tryptophan, tyrosine, or valine.
