We liked Ecoconcepts USA on first sight. Their website is well done, and the business approach so sensible sounding, we were an easy sell. Here's the short list of ordinates they formulate by: - ingredients readily biodegradable and all have low aquatic toxicity; - every ingredient renewable; - market focus on concentrates to reduce packaging and fuel; and - all products designed to be safe for human contact. Plus, the formulations have low-to-no Volatile Organic Compounds (VOCs) and only contain dyes that are approved by the FDA for human consumption. That's more meaningful than the typical "organic" or "natural" labels approach if you need to look at all factors in balance. It'll be worthwhile to have a look at the "before and after" gallery and then download a material safety data sheet (MSDS). Hats off to EcoConcepts for the effort at risk communication and a circumspect formulation approach.
