mehr Infos zu Ökotex 100

Textile products of all processing stages, from yarns to finished fabrics as well as finished articles, are basically suitable for certification according to the OEKO-TEX® STANDARD 100.

If a textile article has been awarded the STANDARD 100 label, you can be sure that all components of this article, i.e. also all threads, buttons and other accessories, have been tested for harmful substances and the article is therefore harmless to health. The testing is carried out by our independent OEKO-TEX® institutes on the basis of our comprehensive OEKO-TEX® criteria catalog. In the testing procedure, they take into account numerous both regulated and non-regulated substances that could be harmful to human health.

In many cases, the limit values set for STANDARD 100 exceed national and international requirements. The criteria catalog is updated at least once a year and expanded to include new scientific findings or legal requirements.

Product class 1 includes products for babies and has the strictest requirements and limit values.
All yarns from Atelier Zitron are product class 1 certified.
