Abstract

Abstract Tocopherol diester derivatives having high vitamin E potency can be produced by the esterification of tocopherol acid esters with amino alcohols. Some preferred tocopherol diesters also have excellent water solubility. One of the preferred diesters is the tocopherol diester having choline, a vitamin B 4 moiety.
