California recently passed a law requiring manufacturers of various cleaning products to comply with the strictest chemical disclosure regulations in the United States to date by January 1, 2021, while online disclosure must be implemented by January 1, 2020. Experts believe that if the new law is not rejected by a California referendum or successfully challenged in court, it will become the de facto national standard. This is because manufacturers may find it more practical and cost-effective to create labels that comply with California standards and then use them on cleaning products marketed nationwide. California's Right to Know Cleaning Products Act (SB 258), passed on October 15, requires manufacturers of designated cleaning products sold in the state to disclose information about the chemicals contained in their products on product labels and on their product websites. "Designated products" refer to cleaning products primarily used in commercial, household, or institutional settings, including air fresheners, automotive products, general cleaning products, and polishing or floor waxing products. Products not included in this definition are: (1) food, medicine, and cosmetics, including personal care products such as toothpaste, shampoo, and hand soap; (2) industrial products specifically manufactured and used in oil and gas production, steel production, heavy industrial manufacturing, industrial water treatment, industrial textile maintenance and processing (excluding industrial washing), food and beverage processing and packaging, and other industrial production processes; and (3) designated trial samples of products not packaged for individual sale, resale, or retail, with a written statement indicating that the product may not be sold or resold.
