Mixture Hazard Assessment Methodology

This document describes the methodology used to assign a RED, YELLOW, GREEN, or GREY hazard rating to a homogeneous mixture for a select set of toxicity endpoints based on the concentrations of individual component chemicals in the homogeneous mixture. This mixtures assessment methodology may be used as an alternative to the traditional Cradle to Cradle Certifed™ Material Health Assessment Methodology when assigning hazard ratings.
