The present invention relates to a polyethoxylated vitamin E corresponding to the following formula (I): <IMAGE> in which R is -(CH2CH2-O)nH, n is an integer from 2 to 100 A is <IMAGE> or <IMAGE> , B is -CH3 in the 5-, 7- or 8-position and m is an integer from 1 to 3. The compound of the invention, which can be prepared by reacting a vitamin E or an ester of the latter with ethylene oxide, using a basic catalyst under pressure and under anhydrous conditions, has an anti-oxidising nature and a stability to oxidation similar to those of vitamin E acetate and very favourable moisture-retaining and surface activity properties not found in vitamin E and vitamin E acetate. Moreover, the compound is very safe to use in living organisms. The present invention also relates to a process for preparing the compound (I) and to some of its uses.
