Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 46 words
A water-base metal working fluid consisting essentially of water and, as a biocidal and anti-rust agent, the triethanolamine salt of the monomethyl ester of an alkyl or akenyl succinic acid, the alkyl or alkenyl substituent of which contains from about 6 to about 22 carbon atoms.
Claim 2
Dependent Claim 46 words
A water-base metal working fluid consisting essentially of water and, as a biocidal and anti-rust agent, the triethanolamine salt of the monomethyl ester of an alkyl or akenyl succinic acid, the alkyl or alkenyl substituent of which contains from about 6 to about 22 carbon atoms.
Claim 3
Dependent Claim 15 words
The fluid of claim 1 wherein said ester is the monomethyl ester of tetrapropenylsuccinic acid.
Claim 4
Dependent Claim 68 words
The fluid of claim 1 wherein said water is present in an amount of 55%, by weight, and said salt is present in an amount of 45%, by weight, the triethanolamine component thereof being present in an amount of 30%, by weight, of the total composition and the monomethyl ester of tetrapropenylsuccinic acid component thereof being present in an amount of 15%, by weight, of the total composition.
