Dear Ginny, Thank you very much for your mail. It is correct that we allow certain amounts of chemicals to be in our tested products as a residue. The values are chosen so that they are harmless at human health at those concentrations, are equal or below the regulated limits and / or realistic with the current state of the art in the textile industry. I hope I was able to answer your question, if something is still unclear or you have follow-up inquiries I am at your disposal, Best regards Jonathan Wehrli Product Manager ________________________________________ OEKO-TEX® Association Genferstraße 23 | CH-8002 Zurich Phone + 41 44 501 26 00 Direct + 41 44 501 26 03 j.wehrli@oeko-tex.com | www.oeko-tex.com
