U.S. Food and Drug Administration (FDA)
The U.S. Food and Drug Administration (FDA) reviewed the safety of zinc acetate and approved its use as an active ingredient in over-the-counter (OTC) skin protectant drug products at concentrations of 0.1 to 2%.
The FDA’s Select Committee on Generally Recognized as Safe Substances (SCOGS) concluded that there was no evidence in the available information on zinc acetate that demonstrates a hazard to the public when used at levels that are now current and in the manner now practiced.
