A bill to amend the Saccharin Study and Labeling Act to extend the period during which the Secretary of Health, Education, and Welfare is prohibited from taking certain actions restricting the continued use of saccharin as a food, drug, or cosmetic.

Amends the Saccharin Study and Labeling Act to extend to January 3, 1981 (or to the enactment, if earlier, of any law changing the conditions under which a food additive shall not be deemed safe) of the period during which the Secretary of Health, Education, and Welfare is prohibited from taking specified actions restricting the continued use of saccharin as a food, drug, or cosmetic.

Declares void of all legal force or effect any such prohibited action which the Secretary may have taken after the expiration of the initial 18-month prohibition period.
