Cosmetic Ingredients Listed Under California Proposition 65

California Proposition 65 (the Safe Drinking Water and Toxic Enforcement Act of 1986) requires businesses to warn Californians about significant exposures to chemicals that cause cancer, birth defects, or reproductive harm. The Office of Environmental Health Hazard Assessment (OEHHA) maintains the Prop 65 list and publishes No Significant Risk Levels (NSRLs) for carcinogens and Maximum Allowable Dose Levels (MADLs) for reproductive toxicants. A product containing a listed chemical above the safe harbor level must bear a Prop 65 warning. This cluster lists cosmetic ingredients currently on the Prop 65 list with their toxicity endpoint classifications and safe harbor values where published.
