1. A composition comprising components (a), (b), (c), (d) and (e) in the following fractions:
(a) 35 to 40% by weight, based on the total weight of the components (a), (b), (c), (d) and (e), of at least one methyl or ethyl ester of at least one aliphatic C14-C22-carboxylic acid, where the at least one carboxylic acid consists of at least 70% by weight of aliphatic carboxylic acids having 18 carbon atoms, where the aliphatic carboxylic acids having 18 carbon atoms of component (a) is a mixture of at least one saturated C18-carboxylic acid, at least one monounsaturated C18-carboxylic acid, at least one diunsaturated C18-carboxylic acid and at least one triunsaturated C18-carboxylic acid, where the amount of monounsaturated C18-carboxylic acid is at least 60%, based on the total weight of this mixture, where the at least one monounsaturated C18-carboxylic acid comprises oleic acid; (b) 20 to 25% by weight, based on the total weight of the components (a), (b), (c), (d) and (e), of at least one anionic surfactant which is selected from the esterification products of monohydroxy-functional alkyl polyethers with inorganic polyprotonic acids; (c) 3 to 7% by weight, based on the total weight of the components (a), (b), (c), (d) and (e), of at least one aliphatic C14-C22-carboxylic acid, where the fraction of oleic acid is at least 80%, based on the total weight C14-C22-carboxylic acid of component (c); (d) 0 to 0.5% by weight, based on the total weight of the components (a), (b), (c), (d) and (e), of optionally at least one antifoam; and (e) at least one aromatic solvent, 100% by weight, based on the total weight of components (a), (b), (c), (d) and (e). |
