Sorona® Celebrates 5th Year of OEKO-TEX® Standard 100 Certification

The OEKO-TEX® Association congratulates DuPont on the fifth year of OEKO-TEX® Standard 100 certification for DuPont™ Sorona®, the renewably sourced fiber used in apparel, home textiles, and residential, commercial, and automotive carpets. Based on 37% renewable ingredients, Sorona® fiber earned the OEKO-TEX® Standard 100 certification indicating that it has been tested to be free from harmful levels of more than 300 potentially dangerous substances. OEKO-TEX® granted Sorona® a Class 1 certification signifying that it meets the most stringent limit levels OEKO-TEX® requires for products intended for use by infants and toddlers age three and younger.

“The independent, voluntary OEKO-TEX® certification is an important part of the complete Sorona® sustainability story,” says Renee Henze Marketing Leader, at DuPont Biomaterials. “We created Sorona® to be a high performance fiber that is better for the environment but, to be truly sustainable, Sorona® also must not contain substances harmful to the consumer. The OEKO-TEX® testing and certification process confirms this.”

OEKO-TEX® Standard 100 certified products are tested for concerning substances such as pesticides, heavy metals like lead and mercury, formaldehyde, carcinogenic dyes, residual surfactants, and a long list of other chemicals that can have harmful effects on people as well as on the environment. The certification requires annual renewal and OEKO-TEX® conducts site visits and retail audits to help certificate holders maintain the standard’s requirements. Sorona’s OEKO-TEX® certification also means that the fiber can be used in other OEKO-TEX® certified textile and apparel products without concern.

“Long time certificate holders like DuPont™ Sorona® are leaders in the textile industry’s ongoing efforts to operate more sustainably across the global supply chain,” says Ben Mead who represents OEKO-TEX® in North America. “We look forward to continuing our partnership for many years to come.”


The International OEKO-TEX® Association, headquartered in Zurich, Switzerland, was founded in 1992 by the OETI, formerly Austrian Textile Research Institute, and the German Hohenstein Research Institute. Currently, its membership includes 16 independent textile research and testing institutes with their representative offices in 60 countries worldwide. To date, more than 160,000 OEKO-TEX® Standard 100 certificates have been issued—with more than 14,000 issued per year—and 10,000 manufacturers, brands, and retailers in 98 countries are working with OEKO-TEX® to ensure that their products are tested for potentially harmful substances. Now available are the STeP by OEKO-TEX® certification for sustainable textile product manufacturing facilities, the MySTeP by OEKO-TEX® database management tool, the ECO PASSPORT by OEKO-TEX® certification for textile chemical compounds, and the Made in Green by OEKO-TEX® label for OEKO-TEX® Standard 100 certified products produced in accordance with OEKO-TEX® guidelines.
