DESCRIPTION

RRR-α-Tocopherol Concentrate occurs as a brown-red to light yellow, clear, viscous oil. It is a form of vitamin E obtained by the vacuum steam distillation of edible vegetable oil products, comprising a concentrated form of RRR-α-tocopherol. It oxidizes and darkens slowly in air and on exposure to light. It may contain an edible vegetable oil added to adjust the required amount of total tocopherols, and the content of RRR-α-tocopherol may be adjusted by suitable physical and chemical means. It is insoluble in water; soluble in alcohol; and miscible with acetone, with chloroform, with ether, and with vegetable oils.
