Safety Measures/Side Effects:

The Cosmetics Database considers Zinc Stearate a low to moderate hazard ingredient depending on usage. It lists concerns regarding cancer, allergies, immunotoxicity, organ system toxicity, based on high levels of this ingredient given to animals or in vitro studies. The Environmental Canada Domestic Substance List classifies it as a high human health priority and expected to be toxic or harmful, although these classifications are based on occupational hazard studies that resulted in respiratory problems after long-term exposure.

According to OSHA, Zinc Stearate is a human irritant, but "has low acute toxicity in experimental animals. Pure zinc stearate was nonirritating to rabbit skin. Zinc stearates are practically nontoxic to rats on acute ingestion."
