Global standard for safety
About Oeko-tex® Standard 100, Class I Certification
Oeko-tex® Standard 100 is an international safety standard for textile products, established by the international Oeko-tex® Association (based in Switzerland) comprising institutes for research and testing in 24 countries worldwide, especially in Europe.
Application of this standard means to voluntarily restrict hazardous substances that may be found in textiles and to certify safety. Products certified by Oeko-tex® are confirmed to be free of chemicals that are hazardous or possibly hazardous to the human body.
Oeko-tex® Standard 100 certification tests and analyzes products for chemicals that are prohibited/restricted by laws or voluntary restraint around the world and is granted to items that are confirmed to be completely within limits.
