Claims (6)

1. A composition for stabilizing organic polymers consisting of a mixture of:

(a) a sterically hindered phenol having the formula:

wherein n is an integer ranging from 0 to 10; and

(b) a tertiary amine oxide having the formula:

R 1 R 2 R 3 N→O

wherein R 1 is a methyl group and R 2 and R 3 can be the same or different and each is an alkyl group having from 14 to 24 carbon atoms and wherein the sterically hindered phenol is present in an amount between about 20 and about 95% by weight of the mixture of (a) and (b).
