Free RIFM Webinar Explores Human Relevance and Risk in Developmental and Reproductive Toxicology
6.17.26
The Research Institute for Fragrance Materials (RIFM) will host a free webinar, “From High-Dose Studies to Human Relevance: Understanding Fragrance Safety,” on Wednesday, June 24, 2026, from 9:30 AM to 10:30 AM EDT.
As regulatory frameworks evolve, developmental and reproductive toxicity data play an increasingly prominent role in chemical safety discussions. Understanding how laboratory findings translate to human exposure remains a critical challenge for regulators, industry stakeholders, and the scientific community.
This webinar will explore the distinctions among dose, exposure, hazard, and risk, providing a framework for evaluating developmental and reproductive toxicity data. The discussion will examine how toxicologists determine the relevance of study findings to human health and why exposure remains central to risk assessment.
The session features Kaushal Joshi, PhD, DABT, Principal Scientist, Repeated Dose and Reproductive Toxicology at RIFM; Yax Thakkar, PhD, Manager, Scientific Innovation & Discovery at RIFM; and Aldert H. Piersma, PhD, Emeritus Professor of Reproductive Toxicology at the Institute for Risk Assessment Sciences (IRAS), Utrecht University, Netherlands, and member of the Expert Panel for Fragrance Safety.
Speakers will introduce RIFM’s new Developmental and Reproductive Toxicity Data Summary, part of a broader initiative to communicate complex toxicological information through a transparent weight-of-evidence framework that integrates hazard identification, exposure information, mechanistic understanding, and the totality of available scientific evidence.
Participants will learn how findings from high-dose studies are evaluated alongside exposure assessments and evidence to determine their potential relevance to human health. The webinar will also highlight the role of expert judgment in translating complex datasets into safety conclusions.
The Research Institute for Fragrance Materials (RIFM) is the world’s leading resource for the safe use of fragrance ingredients. Founded in 1966, RIFM conducts and supports scientific research and evaluates fragrance materials through internationally recognized safety assessment programs. RIFM’s work helps inform fragrance safety standards and regulatory discussions worldwide.
Registration is free and open to all interested participants.
