Company highlights
Here's the a summary of brands that came out of this initial search from January-February 2018 that had EWG ratings (A-F). Again, not all products are included (and not all companies are included) but this provides an overview of how companies generally compare with each other. These ratings include air fresheners, all purpose cleaners, bathroom cleaners, dish detergents, floor cleaners, kitchen cleaners, and laundry products. Hand soap is classified under the EWG cosmetics database.
Where available, I've listed their environmentally-friendly production efforts based on their websites. Another summary of environmentally friendly companies can be found here.
