In recent decades, no product has been tested and studied as frequently (scientifically) as clothing impregnated with permethrin.
Especially from Germany, multiple scientific studies have been published regarding both the effectiveness of permethrin as well as any potential health risks.
The most recent publication is from 2017, where the German "Bundesinstitut für Risikobewertung" considers permethrin (provided it is applied correctly) as not "sensitive".
This is an international standard that sets requirements for factory-treated clothing with permethrin that helps to protect against tick bites. The standard concerns protective clothing, where the textile is factory-treated with permethrin, after which protective clothing is made from it. The protective clothing as such helps protect against tick bites, with the permethrin treatment being an additional element for this protection.
The company Dermatest GmbH is a research institute in the field of dermatology. They work closely with scientists from the Universities in Paris and Bilbao, who specialize in skincare. We have our permethrin finish dermatologically tested and assessed by Dermatest GmbH every two years. Again, for the coming two years, we have received the certificate "Very Good".
The Oeko-Tex standard is a testing and certification system for textiles, which guarantees that the chemicals used throughout the entire production process are not harmful or hazardous to human health or the environment. For all the fabrics we use as Rovince in our clothing, we can present the Oeko-Tex certificate.
Scientific studies and certificates are available upon request at Rovince.
