This luxurious sanitary handkerchief is manufactured with a fabric called “Jupiter”. This is a woven product which composed polyamide yarns, that are metallized with pure silver. The high silver content leads to the release of silver ions, which destroy microbials and viruses on contact. Studies have shown that “Jupiter” also has a high effectiveness against Coronaviruses which are inactivated within 5 minutes after contact. The product is washable at 60°. Frequent washings and dry cleanings may gradually reduce the product effectivity and result in discoloration. Silver is a biocidal active ingredient according to §67 of the EU Biocide Regulation.
