Patent ID: 8313541

Claim:
A mixture comprising: (a1) 5 to 60% by weight of at least one oil-soluble reaction product (A1) of an aromatic or cycloaliphatic dicarboxylic acid or of a succinic acid substituted by C 8 - to C 30 -hydrocarbon radicals with 2 mol of primary or secondary amines having at least 8 carbon atoms, (b 1) 3 to 40% by weight of at least one oil-soluble aliphatic reaction product (B 1) of an aliphatic α,β-dicarboxylic acid having 4 to 300 carbon atoms or derivatives thereof with primary C 8 - to C 30 -alkyl- or -alkenylamines, (b2) 0 to 30% by weight of at least one oil-soluble aliphatic acid amide (B2) formed from polyamines having 2 to 1000 nitrogen atoms and C 8 - to C 30 -fatty acids or fatty acid analog compounds comprising free carboxyl groups, and (c/d) 5 to 75% by weight of at least one inert diluent which, as well as inert nonpolar diluent components (D), comprises to an extent of at least 20% by weight, based on the total amount of inert diluent, of at least one inert polar diluent (C) selected from the group consisting of C 8 - to C 30 -alkanols, aryl-substituted C 1 - to C 6 -alkanols, C 6 - to C 20 -phenols, monoalkyl monocarboxylates having at least one hydrocarbyl chain having 8 to 30 carbon atoms and dialkyl dicarboxylates having at least one hydrocarbyl chain having 8 to 30 carbon atoms, where the sum of components (a1), (b1), (b2) and (c/d) adds up to 100% by weight.
