ph - neutral magnetic liquid on the basis of an aqueous carrier liquid, a method for their preparation and use

摘要

The invention relates to the composition, preparation and use of environmentally friendly aqueous magneto fluids. The use of sugar surfactants which are completely formed from natural renewable raw materials in combination with the aqueous carrier fluid and the harmless iron oxide particles provide environmentally tolerable magneto fluids which comply with the most modern ecological requirements and open up novel application possibilities, even in medicine.
