From their website:
Over the next several years, we worked tirelessly, researching the best natural, plant-based, sustainable raw materials and utilizing them in countless formulations to test their effectiveness. We listened intently to suggestions from all corners of our industry, particularly the cleaning staff of both large and small cleaning companies. It was important for us to work with and learn from these hard working people, many of which were exposed to toxic chemicals every day. We did learn a lot and we set out on a mission to develop the best performing natural, non-toxic products on the market. This is how Eco-Max was born. Eco-Max is truly Green. We strictly formulate our products with 100% plant based ingredients derived from renewable and sustainable resources. As a result, our cleaners are safe to use and have an extremely low impact on our environment.
