Vytex Natural Rubber Latex (NRL) is a brand of natural rubber latex produced and marketed by Vystar Corporation. Vytex NRL is an alternative material to petroleum-based synthetics and traditional, or Hevea, natural rubber latex. Protein test results show that Vytex NRL typically has 90% fewer antigenic proteins than Hevea natural rubber latex. In May 2009 the U.S. Food and Drug Administration granted 510(k) clearance to market and sell a condom made with Vytex that contains less than 2 μg/dm2 of antigenic proteins. In May 2018, Vystar acquired the assets of UV Flu Technologies.
