Laundry detergent ‘Top’ designated as essential historical material
The National Museum of Nature and Science on Tuesday added Lion Corp’s enzyme-based laundry detergent “Top” to a list of important historical materials that have had an impact on Japanese culture and lives.
Top, which first went on sale in 1979, was among 16 items designated by the Tokyo museum as Essential Historical Materials for Science and Technology. Using protein-removing enzymes, Top has been popular for its environmentally friendly formula and cleaning performance.
Among the other products chosen this time were NEC Corp’s PC-9801 16-bit personal computer, which debuted in 1982, and the Yagi-Uda antenna, the world’s first directional ultrashort-wave antenna that is now used throughout the world in radios and televisions.
The antenna, commonly known as the Yagi antenna, derives its name from one of its developers, Dr Hidetsugu Yagi of Tohoku University.
The latest additions have brought the total number of items on the museum’s list to 225 since it was created in 2008 to preserve the legacy of industrial assets considered significant in the past in Japan.
Those already on the list include Aibo, Sony Corp’s dog-like robot, and camera-equipped cell phones.
Lion, the laundry detergent manufacturer, said it feels greatly honoured by the selection, adding that Top was the first laundry detergent containing enzyme to gain acceptance among consumers.
