  • Publication number: 20080132625
    Abstract: A hot melt adhesive that contains fragrances is provided. The hot melt adhesive can be used to adhere packaging materials to one another and, upon exposure of the adhesive surface, releases a fragrance, in particular at low temperatures. A method for manufacturing such a hot melt adhesive is also provided, wherein the thermal stress from manufacture is kept low.

  • Patent number: 7273580
    Abstract: Process for heating a substrate, which contains, relative to the total weight of the substrate, 0.1 to 70 wt. % of metallic, magnetic, ferrimagnetic, ferromagnetic, antiferromagnetic or superparamagnetic particles having an average particle size of between 1 and 5000 nm, wherein the substrate is exposed to electromagnetic radiation, characterized in that the electromagnetic radiation comprises microwave radiation with a frequency in the range from 1 to 300 GHz and the substrate is simultaneously exposed to a direct-current magnetic field, the field strength of which is at least twice the strength of the earth's magnetic field; use of the process for producing or detaching adhesive bonds; device for the simultaneous production of microwave radiation with a frequency within the range from 1 to 300 GHz and a direct-current magnetic field, the field strength of which is at least twice the strength of the earth's magnetic field.

  • Publication number: 20060182809
    Abstract: A stabilizer-free system for transporting active substances in a biological system of one or more active substances and magnetic particles is characterized in that the particles are provided with active substance(s) on at least part of their surface. Modification of the magnetic particles is not absolutely required in this system. It can be incorporated both into aqueous and oily suspensions and into microemulsions, oil-in-water emulsions, water-in-oil emulsions and also water-in-oil-in-water emulsions.
