50 years of environmental monitoring at Henkel. This is a scientific paper from three Henkel experts: Thorsten Wind, Josef Steber and Johannes Tolls. The article is written in English, with an introduction in German. It contains graphs about the detergent consumption in Germany, about sewage treatment and about phosphate loads in the Rhine.
Here an insight in the content: "The gradually increasing detergents consumption in Germany since 1950 resulted in higher emissions of their ingredients to the environment. The first generation of mineral oil-based surfactants, (......), exhibited poor biodegradability and caused public environmental concerns. This prompted Henkel in 1958 to start a systematic measurement of some main detergent constituents in the River rhine in Germany."

I just read an interesting article in the Economist about the change in consumer shopping habits during this recession. I'm just wondering whether and how the trade will react to the consumer's tight pockets. Did you see already interesting examples. Then share them with us here.

Here is the presentation for advanced classes (14-18 years). Chemistry at its best. Content is f.i. improving wash performance by adding stain remover, biodegradability of surfactants or how bleaching agents work. Useful stuff, just have a look.

Hi everybody,
We decided to have also an English section. I just received the presentations about chemistry in school. So, I thought it a good idea to upload them here. Same material as the German documents, but in English. Hope you find it useful.
Regards, Sabine
