Provided are compositions that contain water-soluble vitamin E derivative mixtures (compositions), such as tocopheryl polyethylene glycol succinate (TPGS), TPGS analogs, TPGS homologs and TPGS derivatives. The water-soluble vitamin E mixtures contain mixtures that include dimers and monomers of the vitamin E derivative, where the amount of dimer is greater than 12%, such as 29%, 35%, 50%, 60%, and the amount of monomer is less than 87%, by weight, of the water-soluble vitamin E derivative mixture. Also provided are products containing the water-soluble vitamin E derivative mixtures, including concentrates for dilution into aqueous beverages and compositions for direct ingestion.
