They give personal care product ingredients a rating of 1 through 10, with 1 being the least hazardous and 10 being the highest. We’re proud to say that out of the non-water ingredients found in our products, 8 of them have an EWG rating of 1 out of 10 – the lowest possible hazard rating. The overall average for our ingredients is an EWG rating of 1.15 out of 10.
