BOENNIGHEIM, Germany—The Institute for Hygiene and Biotechnology (IHB) at the Hohenstein Institute introduces two new labels to the market: Tested quality: Skin friendly and Tested Quality: Hypoallergenic. In order to obtain the labels, harmful substances that may become detached from textile materials are analyzed.
Both IHB seals of approval are based on informative cell culture testing systems, for which the laboratory is accredited at the ZLG (Zentralstelle der Länder für Gesundheitsschutz bei Arzneimitteln und Medizinprodukten), for the purpose of assessing the safety of medical products. Harmful substances which may become detached from textile materials are analyzed. None of the methods require animal testing, and the label Tested Quality: Skin friendly excludes the possibility of damaging effects on skin cells.
The label Tested Quality: Hypoallergenic now offers consumers the security of knowing that textiles do not release any allergy-causing substances. To this end, Hohenstein scientists use cells from the immune system, which are considered the skin’s sentry cells. Their task in the human skin is to gather and recognize intruding antigens from neighboring cells of the epidermis and to initiate the corresponding immune response. For this reason, the cells can be used to assess the presence of allergens in textiles.
The two new labels supplement the Hohenstein quality seal for testing the anti-microbial activity of textiles, introduced several years ago. In this vein, the Institute for Hygiene und Biotechnology now offers three certifications for manufacturers, which allows them to represent the results of the extensive laboratory testing done at IHB in a manner oriented towards end users.
