Abstract
A natural vitamin E preparation, i.e. vitamin E extracted from natural sources, comprising one or more of the alpha-, beta-, gamma- and delta-tocopherol forms, either as the tocopherol itself, or as a derivative, such as the acetate, in which the total concentration of Wendt PAHs is less than 100 ppb.
Claims11
A preparation comprising vitamin E extracted from natural sources, wherein the vitamin E is present as one or more of the alpha-, beta-, gamma- or delta-tocopherol forms, either as the tocopherol itself, or in a pharmacologically, nutritionally or cosmetically acceptable form, and wherein the total concentration of Wendt polycyclic aromatic hydrocarbons (PAHs) is less than 100 ppb.
A nutritional supplement or food additive comprising a vitamin E preparation extracted from natural sources, wherein the vitamin E is present as one or more of the alpha-, beta-, gamma- or delta-tocopherol forms, either as the tocopherol itself, or in a nutritionally acceptable form, and wherein the total concentration of Wendt PAHs is less than 100 ppb.
A pharmaceutical composition comprising a vitamin E preparation extracted from natural sources, wherein the vitamin E is present as one or more of the alpha-, beta, gamma- or delta-tocopherol forms, either as the tocopherol itself, or in a pharmacologically acceptable form, and wherein the total concentration of Wendt PAHs is less than 100 ppb.
A skin care product comprising a vitamin E preparation extracted from natural sources, wherein the vitamin E is present as one or more of the alpha-, beta-, gamma- or delta-tocopherol forms, either as the tocopherol itself, or in a cosmetically acceptable form, and wherein the total concentration of Wendt PAHs is less than 100 ppb.
A process of reducing the PAH levels in vitamin E comprising treating a composition comprising vitamin E extracted from natural sources, wherein the vitamin E is present as one or more of the alpha, beta-, gamma-, or delta-tocopherol by liquid/liquid extraction, high pressure liquid chromatography, flash chromatography, complex formation, supercritical fluid extraction or combinations thereof to reduce the PHAs level to a total concentration of Wendt PAHs to less than 100 ppb.
