The history of Düring AG
Maria Düring developed a hydrochloric acid based decalcification agent and thus laid the foundation for the company. This was the birth of the durgol brand; the first efficient and safe decalcifier, durgol forte, subsequently took the Swiss household market by storm.
The early years
The history of this family-owned company began in 1951, in a cellar beneath a house near Zurich's Bucheggplatz. Today's Düring AG is founded on the work of Maria Düring, a housewife with a finely tuned appreciation of consumers' needs and wishes. To tackle the problem of a limescale-blighted toilet in her house she began to experiment with various chemicals, and, in due course, invented a hydrochloric acid based decalcifier. The durgol brand was born.
Maria Düring loaded the product into her car boot and personally visited potential customers. School caretakers in particular proved to be the most rewarding prospects in those early days. Elegantly dressed, wearing a hat and veil, she did not shrink from taking the hands-on approach, even cleaning the toilets of prospective customers. Needless to say she made a lasting impression on them! Chapter one of the success story of durgol forte, the first efficient and safe household decalcification agent, was thus written.
Innovative and entrepreneurial
Walter Düring, son of Maria Düring and a druggist by profession, joined the business and quickly made his mark, for example by personally constructing the first professional filling machine for durgol. The company is especially proud of this in-house developed filling equipment. In 1966 he formulated durgol WC, a special limescale remover for toilets sold in an ergonomic bottle with a curved neck. Two years later this product was followed by another highly efficient decalcifier, durgol ME (today's durgol universal). Decalcification of metal items was made possible for the first time ever thanks to the inclusion of anticorrosive substances, and the new product soon became the market leader in Switzerland.
Launched in 1980, the TOILET DUCK was a further significant product of Walter Düring's restless inventive genius. It revolutionised toilet hygiene and achieved global fame. The initial recipe was produced by Walter Düring's wife Vera. Further variants and product refinements were introduced over the following years. The TOILET DUCK trademark rights were sold at the end of 2008, and Düring AG once again focused squarely on its core business, decalcification. Since then, the resources thus released have been invested in the well-targeted development of further innovations.
Düring AG remains a family-owned company. Members of the third generation of the founding family are closely involved in the company, on the board of directors and in its day-to-day business activities. They ensure that the company continues to embrace fundamental values such as Swiss quality and dependability.
Made in Switzerland, sold the world over
The sole development and production facility in Dällikon turns out ten million bottles of durgol annually and ships them to customers all over the world. durgol holds a share of just over 30 per cent of the Swiss decalcifier market, and the Düring AG products also sell particularly well in Germany, Austria, Israel and the USA. Various expansion plans are in the pipeline.
Although Düring AG with its durgol products enjoys a fine reputation in many countries as an authority in the decalcification field, the company will continue to operate from its Swiss base. Düring AG's vision is that, at some point in the future, Switzerland will be as renowned in the world for its decalcifiers, for durgol, as it is for its watches and chocolate.
