smartcel™ sensitive
The secret from nature in one fiber to protect and care for the skin.

smartcel™ sensitive is an innovative fiber based on natural cellulose, which includes the essential trace element zinc. Zinc has perhaps a greater impact on our wellbeing than any other trace element. It is vital for our immune system, sensory functions and metabolism as well as skin regeneration and protection.
Using only high-quality, pharmaceutical grade 4 zinc oxide, smartcel™ sensitive combines zinc’s regenerative and skin protective effects with its hygienic and antibacterial elements. The fiber is produced without the use of aggressive chemicals and is made solely from renewable raw materials, making it both eco-friendly and fully biodegradable.
Special high graded zinc is melted and oxidised which results in a white powder of pure zinc oxide that is incorporated into a cellulose fiber.

A fiber that provides care and protection for the skin
smartcel™ sensitive is skin friendly thanks to zinc oxide’s soothing and anti-inflammatory capabilities. This is especially useful for people with sensitive skin or skin conditions such as eczema or neurodermitis.
Clinical studies with home textiles and underwear have proven that smartcel™ sensitive provides relief to people with eczema, allergies, neurodermatitis etc.
Zinc oxide also acts as a shield against harmful UVA and UVB radiation, which can damage our skin cells. Depending on the percentage of smartcel™ sensitive used in any garment, it can provid UPF 50+ (Standard AS/NZS 4339:2017).
Further to this, zinc oxide possesses strong antibacterial properties, especially against odour causing bacteria, which helps to make garments stay fresh longer.*
*For customers in European markets: Please note that zinc, despite its undisputed natural antibacterial properties and the fact that it has long confirmed its status as an essential component in recognized cosmetic products of all kinds, is not listed as a biocide. It must therefore not be used for antibacterial applications in Europe. By contrast, smartcel™ sensitive in the U.S. and Asian markets is based
on specific characteristics of the zinc oxide successfully used and applied in medical and antibacterial products.
A patented high-tech process that guarantees long-lasting quality
smartcel™ sensitive is produced using the Lyocell Process, an innovative and eco-friendly production method. Production takes place in a closed loop with no chemicals released. This meets the expectations of our industry both today and in the future. It is one reason why the European Union awarded the procedure with the 2000 European Environmental Award in the category “technology for sustainable development”.
The innovative fibers are produced exclusively for smartfiber AG on modern fiber production plants at Lenzing AG in Austria. A highly specialized team of engineers and scientists supervises the production process on site.
Thanks to our patented manufacturing process, the zinc in smartcel™ sensitive is preserved and permanently embedded into the fiber, even after multiple washing cycles.
Added value for a wide range of applications
If you are looking for an environmentally sound fiber that offers maximum comfort together with high functionality, smartcel™ sensitive is the natural choice.
The fiber is suitable for a vast range of applications, from sport and fashion clothing, underwear and loungewear to home textiles, and combines easily with any other fiber. It adds a smooth, silky feel to any fabric, together with the comfort and care elements required from a generation with an active, health-conscious lifestyle.
