OEKO-TEX® ECO PASSPORT is an independent certification system for chemicals, dyes and additives used in the textile and leather industry. Puratex® is the only impregnator in Europe certified with this passport. During a multi-step process, it is analyzed whether each individual ingredient in the chemical product meets legal requirements and whether it is not harmful to human health. Both brands and manufacturers value the ECO PASSPORT as credible proof of sustainable production.
