    • The present invention relates to mixtures of citric acid esters of the formula I, where R1, R2 and R3 each are aliphatic C5 or C9 groups, characterized in that the average chain length of the aliphatic groups in the mixture is in the range between greater than 5 and 7 and the average degree of branching of the aliphatic C9 groups is in the range between 0.9 and 2.2. The present invention also relates to the use of the citric acid ester mixture according to the invention as a plasticizer in plastic compositions. The present invention furthermore relates to a composition containing the citric acid ester mixture according to the invention in a mixture with additional components, containing plasticizers from the group of the alkyl esters of aromatic polycarboxylic acids, cyclohexane polycarboxylic acids, benzoic acid, or adipic acid, and to the use of such a plasticizer composition in plastic compositions, adhesives, sealing compounds, lacquers, paints, plastisols or inks. Plastic products produced from the plasticizers according to the invention can include profiled sections, seals, food packaging, films, toys, medical articles, sheet roofing, synthetic leather, floor coverings, underbody sealers, coated fabrics, wallpaper, cables and wire sheathings.
