Abstract
The invention relates to a water-dispersible or water-soluble compound having the structure I ##STR1## wherein, R.sup.1,R.sup.2, and R.sup.3 are, independently, hydrogen or methyl, and R.sup.4 is--(CH.sub.2 CH.sub.2 O).sub.n CH.sub.2 CH.sub.2 OH, wherein n is from 10 to 100, wherein compound I is the substantially pure D-enantiomer. The invention further relates to a water-dispersible or water-soluble compound having the structure II ##STR2## wherein, R.sup.1, R.sup.2, and R.sup.3 are, independently, hydrogen or methyl, or the salt thereof, wherein compound II is the substantially pure D-enantiomer. The invention further relates to methods for making the tocotrienol compounds of the present invention.
