Caribbean smell of leather car seats: this is possible thanks to the use of microcapsules of plastic. Using a new technology, researchers at Bayer Chemicals packaged the most diverse in a fine nanopelícula aromas to form tiny spheres. When pulverized these nanospheres on leather or textile, they release relaxing or exotic aromas to be touched.

Transparent and irisadas areas that are blinking and seem to float, apretadísimas some above others. SOAP bubbles? does crystal balls?, none of the two things. They are plastic microcapsules, not visible to the naked eye. The real of each diameter is about 5 micrometers, i.e. a few thousandths of a millimeter. And the particularity of these tiny areas is only seen under a microscope: its wrappings are very thin, but stronger that a film of SOAP water transparent and very elastic. The film around the capsule has only a few nanometers in thickness and is composed of a plastic called polyurea.

It seems almost unimaginable that anything is no in the areas, however, its interior is home to tiny amounts of an aromatic compound. To submit to pressure, the film breaks out as if it were a balloon and releases its fragrant contents. This occurs, for example, with the fresh scent of Blue line off of a car leather seat when a driver is recuesta about it. Blue line is the name of one of the two aromatic notes that specialists in leather of Bayer Chemicals have been packaged in microcapsules to spray them directly on the leather, finely distributed in a liquid. The other is called Cuir naturelle vitessence, provides for leather products which nowadays cannot be recognised by smell familiar to genuine leather smell. These two flavours are the first line of product Euderm that this chemical company has developed for the leather industry.
