ABSTRACT Pink discoloration in amine antioxidant and antiozonant emulsions utilized in the latex industry at high pH has been prevented or retarded by the addition of stabilizers selected from dialkylhydroxylamines or mercaptans. These stabilizers are added at a ratio of from 0.1 to 5 parts by weight per 100 parts by weight of the age resister. In addition, a reversal of discoloration in a liquid amine antioxidant has been achieved by mixing the same type of stabilizer directly with the antioxidant.
