Abstract
A method of inhibiting the autooxidation of fatty acids in a paper product made from pulp fiber is accomplished by adding to the pulp fiber between about 1 mole/metric ton and about 25 moles/metric ton, preferably between about 2 moles/metric ton and about 10 moles/metric ton of an oxidizing halogen.
Claims5
A method of inhibiting the autoxidation of unsaturated fatty acids in a paper product made from pulp fiber, said method comprising contacting unsaturated fatty acids in the pulp fiber with a halohydantoin, wherein said contacting comprises adding to the pulp fiber between about 2 moles/metric ton and about 10 moles/metric;
- ton of a halohydantoin.
A method of inhibiting the autoxidation of fatty acids in a paper product made from pulp fiber, said method comprising contacting unsaturated fatty acids in the pulp fiber with a halohydantoin, wherein said contacting comprises adding between about 1 mole/metic ton and about 25 moles/metric ton of a halohydantoin to a thick stock of at least about 2% pulp fiber.
