Select Committee on GRAS Substances (SCOGS) Opinion: Sulfuric Acid

The GRAS Substances (SCOGS) Database allows access to opinions and conclusions from 115 SCOGS reports published between 1972-1980 on the safety of over 370 Generally Recognized As Safe (GRAS) food substances. The GRAS ingredient reviews were conducted by the Select Committee in response to a 1969 White House directive by President Richard M. Nixon.

Sulfuric Acid

  • SCOGS-Report Number: 33*
  • Type Of Conclusion: 1
  • ID Code: 7664-93-9
  • Year: 1975
  • 21 CFR Section: 184.1095

SCOGS Opinion:

Sulfates are natural constituents of foods and normal products of sulfur metabolism in animals. In much of the published literature, toxicity evaluation of the sulfates has not been the primary objective of the work conducted, but it is evident that the toxic manifestations following oral administration of the sulfates considered in this report appear only at levels that are many times greater than those to which man is exposed in his daily diet. In light of the information contained in this report the Select Committee concludes that: There is no evidence in the available information on sulfuric acid, and on ammonium, calcium, potassium, and sodium sulfates that demonstrates, or suggests reasonable grounds to suspect, a hazard to the public when they are used at levels that are now current or that might reasonably be expected in future.
