Six Classes


Though there are many thousands of chemicals in use, there are just six families or “classes” of chemicals which contain many of the harmful substances found in everyday products. Green Science Policy Institute recently hosted an eight-week educational webinar series to inform manufacturers, retailers and consumers about where these chemicals can be found, how they can be avoided, and what alternatives might be available.
