As CARB continues to evaluate future regulatory approaches for consumer products, Maximum Incremental Reactivity (MIR) is becoming an increasingly important concept for companies that formulate, manufacture, or market personal care products.

This webinar provided a practical overview of Reactivity, including how CARB uses reactivity metrics to assess ozone-forming potential, how MIR differs from traditional mass-based volatile organic compound (VOC) regulation, and why these concepts are receiving renewed attention in connection with consumer product survey data and future rulemaking discussions.

Attendees gained a better understanding of key terms, including MIR, Product-Weighted Maximum Incremental Reactivity (PWMIR), Reactive Organic Gas (ROG), and ozone-forming potential, as well as the potential implications for fragrances, aerosols, and other product categories.

The session was designed for regulatory, formulation, product stewardship, and legal professionals seeking to better understand the direction of CARB’s consumer products program and what it could mean for future compliance strategies.
