Origin and properties of the ingredients

The main active ingredients in the Sonett Tabs are soda, silicates and sulfated castor oil. Silicates are obtained by fusing sand with soda and, due to their alkalinity, are able to saponify the fat on the dishes and make it water-soluble. Adhering food residues are swollen and removed by these silicates. Soda, made from table salt and lime, distributes the fat into fine droplets and thus supports the fat-dissolving power of the silicates. The addition of small amounts of sulfated castor oil reduces the surface tension of the water so that the dirt can be better wetted by the water. Sulfated castor oil, also called Turkish red oil, is obtained by reacting castor oil with sulfuric acid. In addition, the tabs contain bleaching oxygen (sodium percarbonate). During the rinse cycle, sodium percarbonate splits off oxygen in addition to water and soda. The oxygen released is used to remove tea and coffee residues on glasses and cups. Sodium percarbonate is an addition compound of hydrogen peroxide with soda (sodium carbonate). Citrate, obtained during the fermentation of sugary by-products such as molasses, is added to the dishwasher detergent to bind the limescale in the dishwasher water and protect the machine from deposits. Since many dishwashers still feed in too much lime-rich water despite the built-in ion exchanger (water softening system), the citrate is strengthened by the lime-binding power of sodium gluconate, carboxymethyl inulin and tetrasodium glutamate diacetate. Sodium gluconate is the salt of the gluconic acids found naturally in honey and fruit. Carboxymethyl inulin is produced by carboxymethylating inulin, a starch obtained from chicory roots. Tetrasodium glutamate diacetate consists of approx. 86% renewable natural substances containing starch and sugar.

Further information on INCI designations ‣


Silicates and soda are mineral substances that do not have to be broken down further in nature. Citrate, a substance present in plants, animals and humans, is completely broken down in nature by the naturally present microorganisms in 2-3 days. Sodium percarbonate decomposes itself into mineral soda, water and oxygen during the washing and bleaching process and thus leaves the dishwasher in a state that does not require any further decomposition. This means that the bleaching process is also the degradation process. During the manufacturing process of sugar tenside and sulfated castor oil, parts of starch, sugar and fat are removed from the vegetable raw materials, but their natural structure is completely retained. It is therefore relatively easy for the microorganisms to quickly and completely degrade these surfactants to 100%. According to the OECD, citrate, carboxymethyl inulin, tetrasodium glutamate diacetate and sodium gluconate, sugar surfactants and sulfated castor oil are considered to be readily biodegradable.
