Understanding scores

EWG provides information on cleaning product ingredients from the published scientific literature, to supplement incomplete data available from companies and the government. The ratings indicate the relative level of concern posed by exposure to the ingredients in this product - not the product itself - compared to other product formulations. The ratings reflect potential health hazards but do not account for the level of exposure or individual susceptibility, factors which determine actual health risks, if any.

HOW WE DETERMINE SCORES

Hazard score

The Healthy Cleaning ingredient hazard score, from A to F, reflects known and suspected hazards linked to the ingredients. The EWG VERIFIED® mark means a product meets EWG’s strictest criteria for transparency and health.
