Compare hazards, avoid restricted substances, and find safer alternatives.
The Chemical Hazard Data Commons is a tool to help scientists, researchers, and product innovators identify problematic chemicals and collaborate to find safer alternatives. With an active community forum and an ever-expanding library of substances — built on HBN’s powerful Pharos database — the Data Commons is more than just a new way to search for chemical information. It is a shared dynamic space fostering ideas, dialogue, and a future where products free of chemical hazards are the norm and accessible to everyone.
The Data Commons provides comprehensive hazard data for over 57,000 chemicals. Find chemicals, get GreenScreen List Translator Scores, check chemicals against RSLs, and get chemical identifiers and key characteristics.
