DuPont's Sorona polymer, which is made from renewable plant sources such as corn, has been awarded the stringent Oeko-Tex Class 1 certification which allows it to be used in textiles and clothing used by infants and toddlers.

The certification granted by the Hohenstein Textile Testing Institute "provides third party validation of the safety of Sorona for use in all fibre applications," says global business director Walter Fields. "This will benefit our downstream customers, and we will work with them to get further Oeko-Tex certification throughout the supply chain."

Sorona is made, in part, with annually renewable plant-based resources instead of traditional petrochemical ingredients. Its production is also said to reduce energy use and CO2 emissions compared with fibres like nylon.

Oeko-Tex certification verifies the material is free from dangerous levels of harmful substances and meets REACH and CPSIA requirements in the EU and US.

In apparel Sorona can be blended with a range of other natural and synthetic fibres to provide softness, comfort stretch, durability and easy care to a wide variety of garments including swimwear, intimate apparel, denim and ready-to wear.
