Abstract
Anti-oxidants for natural and processed oils, including fish oil and fish meal and animal feed, are 8-substituted ethoxyquin derivatives which, unlike ethoxyquin, do not dimerize on oxidation. Many of the derivatives are novel compounds.
Claims15
A composition comprising a natural or processed oil and an anti-oxidant amount of a compound of the formula
- wherein R is C.sub.1-5 alkyl and X is not hydrogen but a substituent which prevents dimerisation of the compound on oxidation but does not substantially decrease the anti-oxidant effect of the compound below that when X is H.
A composition comprising fish meal or fish oil and an anti-oxidant effective amount of a compound of the formula ##STR2## wherein R is C.sub.1-5 alkyl and X is not hydrogen but a substituent which prevents dimerisation of the compound on oxidation but does not substantially decrease the anti-oxidant effect of the compound below that when X is H.
An animal feed composition comprising an anti-oxidant effective amount of a compound of the formula ##STR3## wherein R is C.sub.1-5 alkyl and X is not hydrogen but a substituent which prevents dimerisation of the compound on oxidation but does not substantially decrease the anti-oxidation but does not substantially decrease the anti-oxidant effect of the compound below that when X is H.
