Background
California’s Proposition 65 continues to play a significant role in shaping ingredient management, labeling practices, and overall compliance strategies not only for cosmetics and personal care companies, but also for businesses in the chemical, food, and broader consumer product sectors. Under the administration of the Office of Environmental Health Hazard Assessment (OEHHA), the program has undergone ongoing updates that directly impact how businesses evaluate chemical exposures, apply warnings, and manage supply chain documentation. As regulatory expectations evolve, companies manufacturing in or selling into California must stay informed of new developments to ensure continued compliance with Proposition 65 requirements.
In this webinar, Julia Dolloff, Proposition 65 Ombudsperson at the California OEHHA, will provide a comprehensive overview of business obligations under Proposition 65, including warning requirements, exposure assessment considerations, and practical compliance strategies. The session will also cover recent regulatory amendments, program updates, and insights into OEHHA’s current priorities and future direction, helping companies from cosmetics, chemicals, food, and other consumer product industries better understand upcoming challenges and prepare for regulatory changes ahead.
