Understanding Chemical Risk

Risk vs. Hazard

A hazard is the potential for harm, while risk considers how likely you are to actually be harmed based on your exposure. A chemical might be hazardous, but if your exposure is very low, your actual risk may be minimal. The information here focuses on chemicals where typical consumer exposure levels may be concerning.

Why These Chemicals?

This database focuses on chemicals that: (1) are commonly found in consumer products, (2) have scientific evidence suggesting potential health or environmental concerns, and (3) can reasonably be avoided through product choices. It's not a comprehensive list of all chemicals of concern.

A Note on "Natural" vs. "Synthetic"

A chemical's origin (natural or synthetic) doesn't determine its safety. Some natural substances are harmful, and some synthetic ones are perfectly safe. What matters is the specific chemical structure and your exposure level. Always evaluate products based on their specific ingredients, not marketing terms.
