A corrosion inhibiting composition comprising:
A) 40-90% by weight of a carboxylic acid corrosion inhibitor, or a water-soluble salt thereof, comprising one or more of:
A1) a triazine-carboxylic acid of formula I:
in which Z is a C₁-C₁₁ alkylene group, R₁ and R₂, independently, are hydrogen or methyl, and R₃ is a group -NR₄R₅ in which R₄ is C₁-C₁₂ alkyl or -Z-COOH in which Z has its previous significance, and R₅ is hydrogen or C₁-C₁₂ alkyl, or a water-soluble salt thereof;
A2) a sulphonamidocarboxylic acid of formula II:
in which R₆ and R₇, independently, are hydrogen or C₁-C₄ alkyl, and m is an integer ranging from 1 to 10 or a water-soluble salt thereof; and
A3) a dicarboxylic acid, or mixture thereof, having the formula III:
HOOC-(CH₂)n-COOH III
in which n is an integer ranging from 4 to 12, or a water-soluble salt thereof;
B) 10-60% by weight of one or more aminobenzoic acids having the formula IV:
in which R₈ is hydrogen or a group of formula V or VI:
or one or more water-soluble salts thereof;
C) 0-10% by weight of an alkanolamine of formula VII:
NR₉R₁₀R₁₁ VII
in which R₉,R₁₀ and R₁₁, independently, are hydrogen, a linear or branched C₁-C₁₂ alkyl group which is optionally interrupted by an oxygen atom, or R₉,R₁₀ and R₁₁ are a group of formula VIII:
where R₁₂ and R₁₃, independently, are hydrogen or C₁-C₁₂ alkyl and p and q, independently, are 0 or an integer ranging from 1 to 10, provided that p and q are not simultaneously 0 and provided that at least one of R₉,R₁₀ and R₁₁ is a group of formula VIII; and
D) 0-10% by weight of an alkali metal borate;
the percentages by weight being based on the total weight of the corrosion inhibitor composition.
