Sinner Circle
The Sinner's Circle is a mechanism by which cleaning processes in commercial cleaning, building cleaning , disinfection , dishwasher , washing machine , etc. are organized and carried out. The Sinner Circle is named after the surfactant chemist Herbert Sinner (* 1900 in Chemnitz, † 1988 in Hilden), former head of detergent application technology at Henkel .
Factors
The Sinner Circle assumes that four parameters mainly determine the success of a cleaning. These four basic parameters of every cleaning are therefore:
- Chemistry ( cleaning agent , product and its concentration)
- Mechanics (removing dirt, making contact with the cleaning agent)
- temperature
- time
All four factors are interdependent, but their size can be changed. They account for the success of a cleaning or disinfection process, must be in exact proportion to each other and always result in the same total.
In Sinner's Circle, these factors are represented in the form of a circle diagram, which shows how the individual factors can be compensated for by the others. The functional principle is used when, for gentle cleaning, for example, weaker chemicals act longer on the objects to be cleaned in order to achieve an equivalent result. The optimal setting of the factors to the method most favorable for the application guarantees both cleaning success and economy.
Was z. B. Not so long ago soap was used as the only chemical aid in the cleaning of textiles. At that time, the cleaning result could be balanced out primarily with the factors mechanics and time. Laborious rubbing on the washboard was the result. However, if the effect of the chemical factor is improved, for example with modern detergents , the mechanical factor can be reduced or the time spent can be shortened.
Another possibility is to lower the necessary temperature by increasing the washing time. Since z. B. In dishwashers heating the water by far generates the highest costs of a wash cycle, often use is made of economy programs that run significantly longer (usually about 30 minutes longer) at a reduced water temperature (usually about 10 degrees less) and thus in generally show an equally good cleaning result anyway.
