California Proposition 65 is responsible for the chemical warnings you see while shopping.

, also known as California’s Safe Drinking Water and Toxic Enforcement Act, was adopted into law in November 1986 after 63 percent of voters expressed support in a direct initiative vote.  (OEHHA) is responsible for the administration of Prop 65 and the chemical disclosures that you may see today while shopping for clothing or furniture. 

The intent of Prop 65 was to address public concerns about exposure to toxic chemicals in water and consumer products. Thus, OEHHA published a list of chemicals that cause cancer, birth defects, or other reproductive harm. This list has been updated once a year since 1987 and currently includes around 900 different substances, ranging from pesticides and additives to dyes and food. Once a new chemical is added to the list, businesses have a year from the date of the addition to provide warnings. The OEHHA website offers search filters that make  easier based on toxicity and type. Prop 65 requires that California businesses include warnings on all products that can expose consumers to any of the chemicals on the OEHHA list. The original 1986 proposition established that  so most businesses have utilized a consistent and vague disclosure message for products under the list. The only  are ones with less than ten (10) employees or whose products fall under safe harbor levels. Safe harbor indicates that a product that discharges a potentially harmful chemical exposes such low levels that there is no significant risk of cancer or reproductive damage. OEHHA has developed  that businesses should review before attaching any warnings. 

OEHHA has changed Prop 65 warning regulations to inform consumers better in the last decade. In 2016, 

 for businesses’ compliance. This label format includes the name of at least one chemical, a triangular yellow warning symbol, and the website address to OEHHA’s Prop 65 website that can provide additional information.  increases the label size for short-form warnings to 12 inches, allows short-form warnings from product labels to be used online, and modifies signal wording to reference California law. These amendments went into effect on January 21st and are likely to become operative as early as 2023.
