Patent ID: 7790701

Claim:
A silicon-based tocopherol derivative represented by the formula V and by the formula VI, wherein the structure of formula (V) is: wherein n=0 or 1, wherein each of R 1 , R 2 and R 3 are selected from hydrogen and CH 3 and at least one of R 1 , R 2 and R 3 is CH 3 ; R 4 is (CH 2 CH 2 CH 2 CH(CH 3 )) 3 CH 3 , or (CH 2 CH 2 CH═C(CH 3 )) 3 CH 3 ; and each R 5 group is independently selected to be a straight or branched chain group of from one to 10 carbon atoms selected from the group consisting of alkyl, alkenyl, alkoxy, alkenoxy, silyl, siloxy, alkylsilyl, alkenylsilyl, alkylsiloxy and alkenylsiloxy or a straight or branched chain silicone polymer which may have one or more oxygen molecules in the chain; and the structure of formula VI is: wherein R 1 , R 2 and R 3 are independently selected from hydrogen, —CH 3 , —Si(R 6 ) p , —OSi(R 5 ) p , —R 5 Si(R 5 ) p , and —R 5 OSi(R 5 ) p , wherein at least one of R 1 , R 2 and R 3 is —Si(R 6 ) p , —OSi(R 5 ) p , —R 5 Si(R 5 ) p or —R 5 OSi(R 5 ) p , and p is 3; R 4 is (CH 2 CH 2 CH 2 CH(CH 3 )) 3 CH 3 or (CH 2 CH 2 CH═C(CH 3 )) 3 CH 3 ; each R 5 group is independently selected to be either R 6 or, a substituted or unsubstituted, saturated or unsaturated, methyl group; and each R 6 group is independently selected to be hydrogen or a straight or branched chain group of from two to 10 carbon atoms selected from the group consisting of alkyl, alkenyl, alkoxy, alkenoxy, silyl, siloxy, alkylsilyl, alkenylsilyl, alkylsiloxy and alkenylsiloxy or a straight or branched chain silicone polymer which may have one or more oxygen molecules in the chain.
