  • Patent number: 5919490
    Abstract: A preparation for stimulating the blood circulation of the skin comprising a dispersion containing a proportion of finely divided magnetically hard single-domain particles in the dispersion being in the range from 0.01% to 70% by weight, based on the total weight of the dispersion; these particles having a strong coercive field and being in the range 600 to 1200 nm; and the magnetically hard single-domain particles are selected from the group consisting of barium hexaferrite, strontium hexaferrite, undoped barium hexaferrite, undoped strontium hexaferrite, and the mixtures thereof; and the balance up to 100% by weight of a cosmetic or pharmaceutical excipient carrier substance or a pharmaceutical additive, based on the total weight of the dispersion.

  • Patent number: 5800835
    Abstract: The invention relates to a preparation for improving the blood supply. The problem with prior art preparations or processes resides in the fact that soft magnetic components had to be introduced into the body in capsule form or a magnetic field had to be applied after the application of demagnetized particles to the skin. The purpose of the invention is to provide a novel preparation for improving the blood supply in which special hard magnetic particles are used. According to the invention, the preparation for improving the blood supply consists of a pharmaceutically or cosmetically acceptable medium and possibly further additives containing finely distributed hard magnetic single-grade particles with a high coercitive field intensity and grain sizes in the range of 600 to 1200 nm. Dispersions of this preparation exhibit no aggregation of the hard magnetic particles. The preferred use is in the cosmetic and dermatological field.
