Whole Foods recently established what they call their Premium Body Care® standards.
They write: "Our experts spent years examining ingredients according to the strictest criteria for safety, efficacy and impact on the environment [emphasis added]."
I'm regularly at Whole Foods because the local stores around here are accessible by public transportation. I can vouch for the Whole Foods Market Organic Castile Soap Peppermint which meets the PBC standard. http://www.wholefoods.com
