Tennant Company (NYSE: TNC), a leading provider of sustainable cleaning technologies, learned today that the Trading Standards Service of the Oxfordshire County Council, U.K., determined that advertising claims made by Tennant about its patented ec-H2O technology are supported by its scientific evidence and customer testing. In its ruling, the Trading Standards Service found that Tennant can broadly support its claims in relation to ec-H2O on the company’s website and in marketing materials. As a result, the Trading Standards Service has declined to further investigate the challenge raised by German competitor Karcher. “We are extremely pleased with Trading Standards Service’s decision,” said Chris Killingstad, Tennant Company’s president and chief executive officer. “We take pride in the integrity of our business and in the value of our products, and this further supports that commitment.” Company Profile Minneapolis-based Tennant Company (NYSE: TNC) is a world leader in designing, manufacturing and marketing solutions that help create a cleaner, safer, healthier world.
