Earth Friendly Products are "champion" in the eyes of the Environmental Protection Agency and its Safer Detergents Stewardship Initiative, or SDSI. Earth Friendly Products are committed to the use of safe surfactants (wetting agents in detergent "that break down quickly to non-polluting compounds and help protect aquatic life in both fresh and salt water," as the EPA says). In accordance with SDSI, Earth Friendly Products are readily biodegradable, non-toxic, free of phosphates, and have a neutral pH. Because they are plant-based and petroleum-free, their surfactants do not bio-accumulate or mimic human hormones. Earth Friendly Products are not tested on animals. Herbspro.com is proud to carry the entire range of this fine brand.
