Compositions comprising a salt of a d-tocopherol compound polybasic acid partial ester of the general formula: [(R-O<t>(O)C)z-Ax-(C(O)O<->y]n[M<n+>]y wherein each R represents a dextrorotatory tocopherol compound moiety and O<t> represents the 6-hydroxyl oxygen atom of the dextrorotatory tocopherol compound moiety, A represents a polyvalent hydrocarbon group having from 1 to 44 carbon atoms which can be linear, branched, cyclic or polycyclic, aliphatic or aromatic, saturated or unsaturated and substituted or unsubstituted, x represents 0 or 1, y and z each independently represent a number of from 1 to 4 wherein the sum of y and z equals a number of from 2 to 6, n represents an integer of from 1 to 6 and M represents a metal ion, with the proviso that where x equals zero both y and z each equal 1; and wherein the composition contains an amount of one or more l-tocopherol compounds which is less than 50% by weight of the total tocopherol compound content in the composition. |
